Like with circular filters, you can absolutely stack square filters in front of one another. Most square filter holders have slots for three square filters.
That being said, remember that stacking too many filters together can cause vignetting, so we would not recommend stacking more than 2 filters together.
Some popular stacking combinations include combining 2 fixed ND filters for a greater ND filter factor, or leaving a UV on your lens and stacking an ND on top. Just remember that you will always get the best image quality with only one filter on your lens.
Urth square filter holders are coming soon. We’ll announce it on our social media accounts when they’re available to purchase.
Urth square filters measure 100mm x 100mm, so you’ll need a square filter holder that carries filters with those dimensions. You’ll also need a square filter holder that matches the filter thread size of the lens you will be screwing the holder on. The filter thread size is usually displayed on the front or side of your lens next to this symbol Ø and will look something like Ø77 or 77mm.

When you want to adjust the colors or contrast in half of your image.
Graduated lens filters help you balance the light intensity in one half of your photographs while maintaining true lighting conditions in the other half. They are commonly used in landscape photography to create a more dramatic sky, while maintaining the foreground’s original contrast and colors.
Yes, the coloured half of the lens increases your f-stop, while the clear half has no effect on your f-stop.
For the coloured half of your lens filter, you’re f-stop in increased as follows.
A lens filter that has colour on one half that gradually fades to no colour.
Graduated lens filters are designed to help balance the light intensity in one half of your photographs while maintaining true lighting conditions in the other half. Think sunrises and sunsets, or shooting in a forest where your image has a big contrast in light that needs to be adjusted.
Yes and it depends on the filter colour.
Color filters are commonly used for black and white photography, but you can use it for creative effect however you see fit.
A common problem in black and white photography is that certain colours look very similar when converted into grayscale. Even some shades of red, green, and blue look completely different in colour, but almost identical in black and white. That’s where colour filters can help. They absorb certain wavelengths of light and reflects others, which helps create a bigger contrast between colours as they appear as different intensities of black and white in your photographs.
Red lens filters are one of the most popular black and white photography filters. They increase visibility in haze and fog and make a blue sky appear almost black, making clouds really stand out, giving the scene a dramatic feel. Red filters can also be used for black and white nature photography to obtain more definition between flowers and foliage, particularly when shooting red flowers.
Yellow lens filters produce the most subtle effect of colour filters, allowing for it to be used in virtually any type of black and white photography. When shooting landscapes the effect will be a subtle contrast compared to the one produced by the red lens filter – slightly darker skies and whiter clouds to balance the dark tone of the ground. In portrait photography, they produce warm, natural, pleasing skin tones. They will also increase the contrast of foliage in nature photography.
Orange lens filters sit between Red and Yellow lens filters and offer a beautiful balance between the effects of the other two lens filters, which makes it a great option for general purposes. In black and white portrait photography, Orange lens filters reduce the appearance of freckles and blemishes, giving the skin a healthy, smooth look. When photographing buildings and cityscapes, the orange tone gives bricks a pleasing tone and increases the contrast between different materials to add depth and texture to the image.
Green lens filters are useful in more specific applications such as plant photography, to separate the green foliage from the brightly-coloured flowers and buds. Similarly for landscape photography to boost the vibrancy of grass and trees. It’s worth noting that green lens filters can lighten the color of the sky.
Blue lens filters are not commonly used in black and white photography since it reduces contrast and makes grey/black colors even darker. However, they can be used when you want to get create a smoother less contrasting effect.
Grey lens filters reduce contrast by evening out the exposure difference between the highlights and shadows in your frame. Ideal for shooting the sky on overcast days to bring out the detail in the clouds.
Different colours have different effects so let your style and location guide you.
Yellow lens filters block yellow light and absorb blue light, giving a subtle enhancement to your images while maintaining a natural look. They’re often used for landscape photography and help enhance contrast and sharpness of subjects at an intermediate distance. A great option for scenes with large areas of blue sky.
Orange lens filters enhance the contrast between yellows and reds, which makes them great for creating darkened, moody skies. A great option for a telephoto lens for distance shots.
Red lens filters absorb blue and green light while also enhancing black and white contrast making it ideal for creating dramatic cloudscapes.
Green lens filters absorb red and blue light, which makes it ideal for portraits of people and trees because it helps correct skin tone.
Blue lens filters slightly darken reds and oranges while lightening blues and greens just a little. It is mostly used for light balancing and creative purposes. It reduces contrast and therefore is rarely used for black-and-white photography.
Grey lens filters reduce contrast by evening out the exposure difference between the highlights and shadows in your frame. Ideal for shooting the sky on overcast days to bring out the detail in the clouds.
Color filters absorb certain wavelengths of color and transmit the other wavelengths allowing them to be seen.
We know that light is the source of color. For example, a blue flower absorbs all other colour wavelengths of light except blue, which it reflects making us see blue. Color filters work the same way, absorbing certain wavelengths and transmitting the other wavelengths. As a result of this, when placing a color filter on your lens, certain colors of the image will be enhanced, and contrast between them may be increased or reduced.
Photographers shooting in black and white, or those who want to apply different colours to their images.
Using colour filters can affect your image contrast in normal and black and white photography. And using colour filters in colour photography will create a layer of colour over your image – often used in fashion photography.
A lens filter that absorbs some colors and allows others to pass through to change the colour of your image.
Depending on the pigmentation of the optical filter, the contrast in the image might be increased or reduced, and some color tones will be enhanced.
So an example of this could be with a yellow filter which absorbs all of the colour spectrum except yellow. This creates more contrast between blue and yellow in the scene you’re shooting which is why it is popular with black and white film photography – it adds more contrast.
There are three main reasons your lens adapter may not work. 1. The adapter fits a different lens mount. 2. The adapter fits a different camera mount. 3. All of the above.
If you’re sure you have the correct lens adapter for your lens and camera body, then there’s a tiny chance it may be a defective product. If that’s the case, please email us with a photo or video explaining the issue.
To ensure you find the right lens adapter, read our guide to buying the right lens adapter.
Make sure you’ve selected the option ‘shoot without lens’ in your camera settings. And ensure all other settings are set to manual too.
Urth lens adapters are fully manual, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, autofocusing) need to be set manually. While this may seem like a disadvantage, we prefer to see it as an opportunity to familiarise yourself with manual photography – what fun!
No, the true focal length of your lens won’t change when using an adapter.
However, if you’re using a full frame sensor lens with an ASP-C or cropped sensor camera, this can change the equivalent or perceived focal length. The camera will apply a crop factor in the lens field of view, which will make the image appear more zoomed in than it did through your viewfinder.
Here is an analogy to help you think of this in a different way: Imagine you have a projector and it’s set up to create an 8×10 metre image – this is your full frame lens. But you only have a projector screen that is 6x8m – this is your APS-C sensor. The screen you have to capture the image is smaller than the image itself, so you can only capture a smaller part of it – your image will be cropped.
Worried? No, conscious? Yes. If you’re using a full frame sensor lens with a crop sensor camera, the image will be cropped by your camera sensor.
This means your lens’ “equivalent focal length” will be longer than its true focal length. This happens when mounting a large sensor/full frame lens on a camera with a smaller/APS-C sensor camera. The camera will apply a crop factor in the lens field of view, which will make the image appear more zoomed in that it did through your viewfinder.
Here is an analogy to help you think of this in a different way: Imagine you have a projector and it’s set up to create an 8×10 metre image – this is your full frame lens. But you only have a projector screen that is 6×8 metres (this is your APS-C sensor). The screen you have to capture the image is smaller than the image itself, so you can only capture a smaller part of it – your image will be cropped.
Most likely because you’re using a crop sensor (APS-C) lens on a full frame camera, which causes vignetting or a black border around your image.
The black border effect isn’t an issue with your lens adapter, it’s because the size of the lens is designed for a smaller camera sensor. So when you use the APS-C lens with a full frame camera sensor, there is a border around the outside where light from the lens cannot reach. This appears as a black band in the image.
Here is an analogy to help you think of this in a different way: Imagine your APS-C lens is a 6×8 photograph and you want to frame it. Your full sensor camera is like a 10×12 picture frame. If you want to use this frame for that photo, there’s going to be some blank space around it.
To avoid this happening, you can use crop sensor lenses with crop sensor cameras, and use full frame sensor lenses with crop sensor cameras although the image will be cropped by the size of your camera sensor.
Slightly, but it’s difficult to see unless you’re printing your image huge.
We use the same Japanese optical glass in our lens adapters as we use in our filters. Having an optical glass element in the lens adapter makes the opening smaller, which slightly decreases light transmittance by less than an f-stop. The glass element acts as a teleconverter to refocus the light, which also has a small effect on image quality.
Find your lens mount and your camera mount.
Identifying your lens mount
The easiest way to find and confirm your lens mount is to know the mount of the camera it was used on originally. A quick internet search of the camera model followed by lens mount is a sure way to confirm what lens mount you need. For example, if you have an old Nikon lens and you know it was used on a Nikon FM2, you can easily find that the lens has a Nikon F-mount. This is particularly useful for lenses that are made for different mounts i.e Sigma and Tamron bring out the same lens with different mounts including EF, F, E so knowing the camera the lens was used on is a good shortcut.
If you have an old second-hand lens and you are unsure of the camera it was made for, take all the known details of the lens and search the web.
Identifying your camera mount
A quick internet search of the camera model followed by lens mount is the quickest way to confirm your camera’s lens mount. E.g. If you have a Sony A7r, a quick search shows it has a Sony E-mount.
Quality, price and that we plant 5 trees for every lens adapter purchased.
Urth lens adapters are made from premium components to ensure your camera and lens mounts are protected. Our lens adapters are made from premium brass and magnalium so you can trust our adapters and focus on experimenting with your new lense-camera combinations. And the biggest difference? We plant 5 trees in areas suffering severe deforestation for every lens adapter purchased.
Yes, but it’s easier to focus using your viewfinder in manual mode.
The biggest challenge you face is accurate manual focusing, especially if you’ve been leaning on autofocus for a while. Best bet is to see which one works for you.
Manually set your aperture.
If your lens has an aperture ring, use that to set the aperture, and if your lens doesn’t you’ll need to set it manually through your camera settings.
No. You need to manually adjust all settings including autofocus, AE metering, and image stabilization.
You will have to change your settings on your lens and camera to manual where possible as the adapter stops electronic communication between the lens and camera.
If there is a switch on your lens that says AF and MF, switch to MF (manual focus). You’ll need to manually set your aperture, shutter speed, and ISO too.
Try changing your camera settings to ‘shoot without lens’.
Our lens adapters are fully manual, and therefore you need to manually set all electronic functions on your lens and camera. If your camera won’t take a photo, it’s probably because your camera can’t sense a lens attached, that’s why you need to set it to ‘shoot without lens’. Ensure all settings on your lens and camera are put into manual mode too.
If your shutter speed, aperture, and ISO are all correct, go into settings and turn on ‘shoot without a lens’.
You need to manually adjust all camera settings when using a lens adapter so remember to check your exposure settings first. If your camera is able to take a photo, it’s likely you simply need to turn on ‘shoot without lens’ in your camera settings.
With some of our adapters you can, but please have a look at the adapter’s product descriptions.
Whenever you want to use a different make of lens with your camera body.
Because you need to use your camera in full manual mode, you may need to familiarise yourself with this before shooting. You’ll soon work out which lenses you enjoy using with your camera. Analogue lenses can provide professional quality glass at a fraction of the cost of modern lenses so lens adapters can help you shoot with better lenses for less.
Attach your lens to the adapter, and then your adapter to your camera body. Put all settings on your lens and camera into manual mode, and select ‘shoot without lens’ in your camera settings.
Attach the lens to the female end of your lens adapter by aligning the red dots located at the rear of the lens with the one at the edge of the adapter ring. Screw in your lens until it clicks or is fastened securely and be sure not to over tighten. Then insert the male end of the adapter to the camera body, by aligning the red dots of your adapter ring and camera body and rotating the adapter until you hear a click – usually in a clockwise direction. Be sure to check everything is firmly attached before picking up the camera to start shooting.
Since all our adapters are fully manual, you need to change your camera settings to manual before you start shooting. This is because a lens adapter doesn’t enable electronic communication to pass from the lens to the camera. You need to manually set your exposure and focus. If your lens does not have a manual aperture control ring, it will stop down to its smallest f-stop by default.
To utilise quality old lenses with your new camera, or match a different make of lens to your camera.
There are countless creative experiments to be explored by mixing different brands of lenses with your camera body. Lens adapters can also help your existing collection of lenses go further with any new cameras you collect. So you can invest in a new camera and make the most of your favourite lenses.
A lens adapter allows you to attach a different brand of lens to your camera body, connecting an otherwise incompatible lens to your camera.
No, sorry.
Our filter kits are pre-assembled so we are unable to take orders for individualised filter kits. All our filters (with the exception of the variable NDX) have the same inner and outer thread size and can be stacked on top of each other. We also sell Filter Caps (front and back) so you can create your own personalized filter kit out of our individual filters and existing filter kits.
Stack ‘em and cap ‘em.
Make sure all filters are stacked together and protected with top and bottom caps. Our filter kit packaging is also designed to be used as extra protection. The cotton bag and the cardboard tube will add an extra layer of protection in your bag.
The Essentials Kit is a great all-round versatile kit if you are hitting the road and need a trusty collection that won’t want to take up much space.
Our Essentials Kit has everything to get you started: A UV filter to protect your lens, a CPL to cut reflection and add colour saturation and ND filters which lets you use wide exposures/longer shutter speeds. Landscape photographers dream kit. If you have a bit more space, add an ND64 to your kit for another dimension of experimentation.
The Basics Kit and The Essentials Kit are great for beginners.
Our Basics and Essentials kits are a great starting point for new photographs. Each kit has its own unique combination of lens filters but both provide great diversity for new photographers without overwhelming them with too many options.
Each filter kit has different lens filters, but all kits include top and bottom caps for safe storage.
All filter kits include a top and bottom filter cap for protection and easy storage. You can peruse our filter kits here.
A filter kit offers you the flexibility to carry different filters in your camera bag using minimal storage.
Our filter kits come with top and bottom lens caps for compact storage and protection while your filters are in your bag. Filter kits provide a huge number of possibilities when shooting and can help you better adapt to extreme shooting conditions.
Photographers who like being equipped with options for unpredictable lighting conditions on their next adventure.
The beauty of shooting outdoors is you never know what conditions you’ll encounter. And when you’re stepping into the unknown, having options can be the difference between heartache and happiness. You don’t know whether you’ll need a CPL filter, ND filter, UV filter, or a colour filter, and when you’re equipped with our filter kits, you’ll be ready to shoot whatever the weather is doing.
A carefully selected collection of lens filters.
Our filter kits are a smarter way to buy a collection of filters. They also come with a top and bottom lens caps for safe and easy storage in your kit.
A fixed ND filter blocks a single f-stop of light exposure, whereas a variable ND filter blocks a range of light exposures.
A Variable ND filter can be rotated to adjust the amount of light being blocked from your camera sensor, whereas a Fixed ND filter blocks out a fixed amount of light. For example, our Variable ND2-400 filter blocks out 1 f-stop – 8 f-stops), and our ND64 blocks 6 f-stops. A Variable ND filter offers more flexibility and is a good option for adventures with unpredictable light conditions. But it’s worth noting Variable NDs have limited applications with wide-angle and telephoto lenses. Read more on that here.
We recommend you don’t. For better results with a telephoto lens, use fixed ND filters.
Using variable ND filters on telephoto lenses can create varied results. Because telephoto lenses use such high-quality optical glass, we recommend you use a fixed ND from our ▲▲▲ professional range on any lens with a focal length >100mm.
Yes, but we suggest you stick to the ND2-32 or ND8-128 variable ND filters.
The ND2-400 has limited application with wide angle lenses. They can be used, but the filter can only be rotated about halfway along the Min to Max range depending on the lens and camera used. That is because variable ND Filters consist of two polarising filters and the upper range of the ND filters varies too much over a wide-angle lens’ field of view, causing issues with the image.
No, you’ll need solar-specific filters that also block infrared light.
Unfortunately, we don’t manufacture solar lens filters. Because of the amount of light you need to filter out, it’s best to buy a solar-specific filter rather than stack up a pile of ND filters. You also need to filter our infrared light.
Because the top layer of glass is a size larger to help avoid vignetting.
The front threads of Variable ND filters are a size bigger to avoid any vignetting. This also means your lens’ original filter cap may not fit on your variable ND. All our lens filters are double threaded so if you want to keep your Variable ND filter attached and use a lens cap, you just need a lens cap that is one size larger. See the handy Variable ND filter cap resizing chart below. You can use one of our filter kit caps, which can be used as a lens cap. Otherwise, you can remove the filter and use your original lens cap.
Keep your filter between the Min and Max marks. Adjust your focal length and position. Another safe bet is to frame your image so that you can crop the dark corners out later.
Darkened corners is known as vignetting and usually occurs with wide-angle lenses. It’s caused by the wide-angle lens’ wide field of view capturing the edge of the lens filter, lens hood or even the lens rim. To avoid vignetting, try a longer lens, or crop the vignetting out when it comes time to publish or print your image. We also recommend you avoid stacking filters to help reduce vignetting. Even taking off your UV filter when using an ND filter will help.
Adjust your cameras white balance settings.
There are a couple of reasons your images may show a slight colour cast when using an ND filter. Check your white balance settings. By restricting the light entering your camera, it may throw out your white balance settings. Manually adjust your white balance settings to reduce any colour cast.
Make sure your filter is set between the Min and Max marks. Adjust your focal length and your position and then reduce the ND’s density value by rotating the ring towards the Min mark until the pattern disappears.
Because there are so many combinations of cameras, lenses, sensors, and other factors, it is very hard to predict which circumstances will create the x-effect. The x-pattern is usually caused by rotating your variable ND filter past its maximum setting. Using a variable ND with a wide-angle lens can increase your chances of encountering an x-pattern. The ND2-400 has limited application with wide angle lenses because the field of view is so broad. The filter can only be rotated about halfway along the Min to Max range without encountering the x-pattern – you can thank physics for this restriction. Variable ND filters consist of two polarizing filters, which can cause issues because the polarizing effect varies so much across the broad field of view of wide-angle lenses. For this reason, we recommend using fixed ND filters, or Variable ND2-32 or ND8-128 with wide-angle lenses, and suggest you avoid stacking filters to avoid any vignetting.
No, Urth ND filters have great colour neutrality.
There are a couple of reasons your images may show a slight colour cast when using an ND filter. Check your white balance settings. By restricting the light entering your camera, it may throw out your white balance settings. Manually adjust your white balance settings to reduce any colour cast.
The best ND filter for your photography will depend on the effects you want to achieve, and the type of lens you’re using.
The first choice you need to make it whether to go for a fixed ND filter, or a variable ND filter. A variable ND filter offers more options, which is great if you’re shooting in unpredictable or variable light conditions. A fixed ND provides a specific light reduction and works better with telephoto and wide angle lenses. And in terms of choosing which range to buy, let the quality of your lenses guide your decision. Read our range guide here.
The next choice you need to make is the level of light reduction you want. The higher the ND number, the more light it stops from reaching your camera sensor.
Urth ND filters and their effective f-stop reductions:
Carefully and with tender, unconditional love. Our cleaning guide has more practical steps.
Start by blowing and then brushing the offending debris with a soft-bristled brush. If that works, you’re good to go. Avoid using the cleaning cloth and lens solution if it’s not necessary. If required, carefully wipe the glass with the microfibre cloth provided and if the debris remains, apply some lens cleaning to the cloth and wipe the filter again in a gentle circular motion.
If you want to reduce the light that goes through your lens by more than 2 f-stops, yes.
While CPL filters polarize light to remove reflections and increase color saturation, ND filters reduce the amount of light that makes it through to your camera’s sensor, which opens up opportunities to experiment with depth of field, slower shutter speeds, and motion blur, even in bright conditions.
Let the quality of your lens guide your choice. Or just go for the best – our ▲▲▲ professional range – if that’s your jive.
Urth has three different ranges of filters: ▲ Entry-level, ▲▲ Mid-tier, and ▲▲▲ Professional. When deciding which range to purchase, the most important factor to consider is the lenses you’ll be using them on. Let the quality of your lens guide your decision because an entry-level lens filter on a professional lens may affect image quality. Our ▲▲▲ professional range is made with German SCHOTT optical glass – considered the best optical glass in the world.
If you are unsure which range is best for you, read our details range guide.
If you’re buying a filter for a telephoto lens (focal length >100mm), we recommend you use a ▲▲▲ professional CPL filter. The quality of the German Schott Glass will match the level of sharpness reached throughout the telephoto lens’ zoom range without affecting image quality.
Yes but only a little – about 2 f-stops.
A CPL filter will reduce the amount of light reaching your sensor by about 2 f-stops.
Maybe it’s the light conditions you’re shooting in, maybe it’s you.
Your CPL filter should cut out the reflected light but remember that you need to rotate the outer element of your CPL filter to do so. To get the maximum polarisation from your CPL filter, use the 90 degree rule. To do this, make an L shape using your thumb and index finger. Point your thumb at the sun and wherever your index finger is pointed, that is the angle that will achieve maximum polarisation.
Yes, do it!
Make sure you have the right size filter and you’re all set. All our filters are designed with a super slim rim to minimise any vignetting that can occur with wide-angle lenses.
A circular polariser allows you to block polarised light from any angle. While a linear polariser can only filter linear polarised light from one direction. A CPL offers more versatility and works better with digital cameras.
Both linear and circular polarizers look the same, and they both do the same thing – reduce reflections on non-metallic surfaces such as water, glass, and wet surfaces, and they increase color saturation too. A CPL filter is essentially a linear polariser with an extra glass element that allows you to adjust your lens filter to block polarised light from different directions.
Let the quality of your lens guide your choice. Or just go for the best – our ▲▲▲ professional range – if that’s your jive.

Beginners, amateurs, professionals – anyone who’d rather replace a damaged lens filter instead of a ruined lens.
A UV filter protects your lens from dirt, dust, sand, moisture, grime, and scratches. It can also protect your lens from any accidental knocks or bumps. It also reduces blue cast created in extremely bright light conditions.
All day, every day. It can stay on your lens at all times.
A UV filter doesn’t affect your camera’s exposure settings, so you can leave it on your lens at all times with the added benefit of it acting as a protective layer over your lens glass. Some pundits say that the extra layer of glass over your lens degrades image quality and can cause lens flare, but using premium quality lens filters can avoid these issues. Ultimately, you need to weigh up the risks and rewards. Keep in mind the difference in cost between replacing a scratched lens filter after a misadventure while shooting versus replacing the entire lens. If you shoot indoors all the time and don’t want anything to come between your lens and your subject, you can definitely take off your UV filter.
Easy, just carefully screw it onto your lens and keep it there at all times. It’s a good idea to loosen it now and then so it doesn’t seize up.
Because a UV filter doesn’ affect your camera settings, you don’t need to do anything with it once you’ve put it on your lens. Most photographers use a UV lens filter to protect their lens glass – especially if they have an expensive lens. UV lens filters prevent dust, dirt, rain, and grime from coming into contact with the lens glass.
UV filters block UV light from reaching your camera sensor, protect your lens, and help improve sharpness in your photographs.
UV Filters cut out haze and blue cast by blocking UV light. They help improve sharpness and clarity in your photographs and protect your camera lens from scratches, dirt, dust, and grime. Using a UV filter doesn’t affect your camera settings, which means you can leave it on your lens at all times. And if you happen to drop your lens or something scratches the lens glass, a lens filter can be the difference between buying a new filter and spending hundreds or thousands of dollars to replace a lens.
You sure can. Our filters are double threaded so you can stack filters to your heart’s content.
All our filters are double-threaded, which means they have back and front threads so you can stack filters of the same thread size. The exception to this rule is the Variable ND filters, which require a larger filter to be stacked on top. E.g. a 58mm Variable ND takes a 62mm thread size on top. However, we recommend you avoid stacking any filters with the Variable ND filter range as it can create vignetting.
Remember that stacking too many filters together can cause vignetting so we would not recommend stacking more than 2 filters together. Some popular stacking combinations include combining 2 fixed ND filters for a greater ND filter factor, and leaving a UV on your lens and stacking a CPL or fixed ND on top. Remember that you will always get the best image quality with just one filter on your lens.
Sorry your filter’s imperfect. Please contact us and we’ll help you.
To make a defect claim, please email us with your order number, photographs (or a video) of the defect, and a short explanation of the defect too. Once we can verify the defect, we’ll find a solution for you in quickly.
Urth lens filters are designed in Australia, and assembled in China using Japanese and German optical glass.
Our lens filters are a global collaboration. All our products are designed in Byron Bay, Australia. Our lens filters are assembled in China using premium magnalium frames and the world’s best optical glass from Japan and Germany.
We think you should buy all of them, but it depends on how and what you want to shoot.
We recommend a UV filter for all your lenses because it provides great protection for your lens glass without affecting your camera settings. Here’s a quick overview of how each type of lens filter can help your photography.
UV Filters
UV filters provide protection for your lens. They also reduce atmospheric haze by blocking UV light from entering your camera sensor.
CPL Filters
Circular Polarising Filters are popular with landscape photographers because they help with image colour saturation, particularly with the sky and trees. They also cut reflections from non-metallic surfaces such as windows, water or wet rocks. If you’re using a telephoto lens (focal length >100mm) we recommended you use our ▲▲▲ CPL.
ND Filters
Neutral Density filters cut a certain amount of light from reaching your camera sensor. This enables you to play with depth of field, motion blur, and long exposures in bright conditions. If you’ve seen those photos with silky looking waterfalls or the sea looking like fluffy fog, chances are an ND filter has created that effect. An ND64 is a great all-round filter and blocks 6 f-stops of light. Another option is a variable ND which offers a range of f-stop values, such as our ND2-400 (1-8 f-stop reductions). If you’re looking to use a variable ND filter with a wide angle lens, we recommend the ND2-32 ND8-128 over the Variable ND2-400. And for telephoto lenses, we recommend using ▲▲▲ ND filters and avoid using variable ND filters so you don’t affect image quality.
The main difference is that German SCHOTT glass has slightly better light transmission.
German Schott B270 optical glass is highly resistant to solar radiation and offers high transmittance in the visible wavelength range. It also has high chemical stability and a fire-polished surface providing excellent image sharpness. The Japanese Optical glass is also a very high-quality optical glass with a very similar light transmission – 99.6% versus the German Schott B270’s 99.8% light transmission.
It is very hard to see the difference in image quality unless using telephoto lenses (focal length >100mm) or enlarging images to be printed in large formats.
The simplest way is to frame your image so you can crop the edges of your image.
Vignetting can occur with wide angle lenses because the field of view is so wide it captures the edge of the lens filter. There are a few things you can do to avoid minimise vignetting.
Before you start shooting, avoid stacking filters with your wide-angle lens. If you’re shooting with a CPL or ND filter, remove your UV filter. And try to use the correct fixed ND instead of stacking multiple ND filters. Note that variable ND filters have two layers of glass and can create more vignetting so they should be avoided. Avoid using a lens hood too as they can increase the chances of vignetting too. If you have a photograph you love but want to remove the vignetting, the best way to do so is to crop your image.
Take it off! We’ll show you some handy hacks for removing it.
In the excitement of trying out your new lens filters, it’s possible to ‘cross thread’ the filter, or over tighten it. Similarly, if you leave a lens filter on for a long period of time, it can seize up and become harder to remove. We recommend you give your filters a bit of a loosen a couple of times a year. The first thing to remember is that you need to unscrew in an anti-clockwise ↺ direction.
Rubber gloves
Rubber gloves provide a much better grip than bare hands (and bear hands have even better grip again but come with other dangers). Washing up gloves are fine, and rubber workwear gloves from a hardware store are a great option too. Alternatively, even placing a rubber band around the rim of your lens filter can provide a better grip. If these solutions don’t work, you can search for some lens filter removal tools before you use Adam Savage’s bandsaw method, which we don’t recommend but do encourage you to watch for fun.
Yes, the only lens filters that requires a different size lens cap are our variable ND filters.
All of our filters include a front thread which allows you to attach a lens cap to your lens filter when it is attached to your lens. The only exceptions are our variable ND filters.
Variable ND filters use a larger layer glass to help avoid vignetting, so your normal lens cap will not fit. For variable ND filters, you need a larger lens cap. Refer to the table below for the relevant filter cap required for each size of our variable ND filters. We sell filter caps individually, which can be used as a screw in lens caps for your filters.
Our products are premium quality – even our entry-level range – we plant 5 trees for every product you purchase, and we’re a proud member of 1% for the planet.
We have three ranges of lens filters – ▲ entry-level range, ▲▲ mid-tier range, and our ▲▲▲ professional range. All of our UV, CPL, and ND filters are made with professional quality optical glass, using either Japanese or German SCHOTT. When comparing similar products, Urth’s price point is usually lower, and we plant 5 trees for each product purchased.
Active environmentalism is one of our core values and we work with Eden Reforestation Projects to help areas devastated by deforestation, and we are a proud member of 1% for the planet, which sees 1% of revenue donated to grassroots environmental organisations around the world.
All of our products are made in strict accordance with the Environmental Standards of RoHS and come in minimal recycled and recyclable packaging. Our individual filters come in a reusable/recyclable robust protective tin case, with a recycled/recyclable EVA foam insert.
Any lens with a focal length 35mm and below is considered wide-angle lenses. And any lens with a focal length 100mm and above is considered telephoto.
14mm Focal Length and below → Fisheye Lens
14mm – 24mm Focal Length → Super Wide-Angle Lens
25mm – 35mm Focal Length → Wide-Angle Lens
36mm – 70mm Focal Length → Standard Lens
71mm – 100mm Focal Length → Medium Telephoto Lens
101mm – 300mm Focal Length → Telephoto Lens
301mm Focal length and above → Super Telephoto Lens
You need a slim profile lens filter to avoid vignetting, so you can choose from any Urth UV, CPL or fixed ND lens filters, but avoid the ND2-400 ND filter as a wide-angle lens limits its range.
For wide-angle lenses, we recommend the ND2-32 or ND8-128 variable ND filters as they are specifically designed for use with wide angles. For a detailed product overview and comparisons between filters, please check our handy filter chart.
The first filter we suggest you buy is a UV filter. It’s a protective filter that doesn’t affect your camera settings, but could save your lens from being damaged. The next filter we recommend is a Circular Polarising Filter and after that, explore ND filters.
UV filters can be left on your lens permanently as no additional coloration or contrast is created and your exposure settings aren’t affected, at the same time, you’ll be protecting your lens.
CPL filters remove reflections and increase colour saturation. They are great for removing unwanted reflections from non-metallic surfaces such as glass or water. A CPL is the perfect filter for cutting through water glare as well as providing a rich blue sky in glary conditions.
When you are ready to start experimenting with aperture and shutter speed settings, reach for an ND filter. ND filters allow you to open up your aperture to achieve a shallow depth of field, and to slow your shutter speed for motion blur, even in bright conditions.
For a detailed product overview and comparisons between filters, please check our handy filter chart.
This will depend on the characteristics and properties you value in your lens filters.
Screw on circular filters, as the name indicates, are made to be screwed on your lens threads and they’re relatively discrete and take up minimal room in your kit when you’re storing them.
A square filter is shaped like a rectangle that exceeds the size of the lens thread area. A filter adapter that screws into your lens and holds the square filter on the other side is needed for attachment. Because of the size of the square lens glass, they are larger and take up a bit more room in your kit
Circular filters
PROS
- Can be left on your lens for instant use
- Can be easily stacked with other filters by screwing them together
- Smaller and lighter than square filters, which makes them easier to store and use
- They are able to seal and protect the front of the lens, keeping out dirt, dust, and grime, and avoiding any problems with light leakage
CONS
- They can only fit a specified thread size (when getting a different thread size lens, you’ll need to get a new filter)
Square filters
PROS
- They can fit multiple lenses with adapter rings
- They are less likely to cause vignetting
- Easier to stack with other square filters
CONS
- Larger and more bulky than circular filters
- Take up more room in your kit
- Slower to fit and use
Because telephoto lenses use high-quality optical glass, we recommend you use our 3 peak range.
For lenses with a focal length 100mm or greater, your telephoto needs to be paired with the best quality optical glass to allow the best sharpness throughout the zoom range.
Thus, we recommend you pair your lens with a UV or CPL filter made with German Schott Glass and a 2 peak fixed ND filter. We recommend fixed ND filters over variable ND filters because it means there are fewer layers of glass over your lens.
The more layers of MRC on a lens filter, the better the protection against scratches, moisture, and oil.
MRC stands for Multi-Resistant Coating and it’s a treatment that protects your filter against scratches and other particles that can affect the filter glass and your image quality. The scratch-resistant, water, and dirt repellent MRC layers make it easier to clean the glass surface and helps to reduce reflection, prevents ghosting and improve the overall image quality.
When deciding which range you should buy, let the quality of your lens guide your choice.
Urth has three different filters ranges: ▲ Entry-level, ▲▲ Mid-tier, and ▲▲▲ Professional. When deciding which range to purchase, the most important factor to consider is the quality of the lenses you’ll be using them on. Let the quality of your lens guide your decision because an entry-level lens filter on a professional lens may affect image quality. Read the full explanation of our the difference in our ranges here.
If you can’t find your filter size, it may mean we are temporarily out of stock.
We make lens filters in 16 different sizes, including 37mm, 39mm, 40.5mm, 43mm, 46mm, 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm 82mm, 86mm, 95mm. If your size is out of stock, you can sign up for a restock alert on the product page.
Treat them with as much love as your hopes and dreams. Store them in their storage tin or protect them with lens caps, and follow our cleaning tips if they need some love.
Ensure you safely store your lens filters when they’re not in use. Our lens filter tins are designed to be used for storage in your camera kit. When they are on your camera lens, treat them with as much care as you would your lens and camera – that means keeping a lens cap on when it’s stored in your bag, and take care when cleaning dust, dirt, or rain from your filter. Become a filter cleaning pro, read our cleaning guide here.
To find the right lens adapter, you need to know which lens mount you want to match with which camera body.
To check if we have the right adapter for your needs, go to our lens adapter page and start by selecting the make of your camera body. Then select the type of lens mount your lens uses, and you’re all set.
The filter thread size is usually displayed on the front or side of your lens next to this symbol Ø and will look something like Ø77 or 77mm.
Your lens filter size is the diameter of your lens measured in millimeters. But you don’t need to measure it, it’s usually printed on the front or side of your lens next to this Ø symbol. Alternatively, you can find your filter size on the back of your lens cap. Please note that the focal length (e.g 24mm) is not your filter size. You can also search for your filter size by entering the specific lens model and filter size. E.g. “Canon EF 24mm f1.4L USM II filter size” and you’ll see it’s 77mm.

WARNING: Formatting will erase all data on the device. Back up all your data before proceeding.
To format a device on your Mac OS X:
1. Double-click on Macintosh HD – or in the Finder menu click File > New Finder Window
2. Click the Applications folder – if using a Finder Window Applications will be in the left side menu.
3. Click the Utilities folder.
4. Double-click Disk Utility.
5. On the left side of the window are the drives connected to the computer. Select the capacity of the drive respective to the one containing the device you wish to format then click the Erase tab.
Example: If the drive is called “NO NAME”, directly above that, you should see the drive capacity of “XXXX”. Select this capacity.
6. Verify Volume Format is set to MS-DOS file system or exFAT, then click Erase.
NOTE: exFAT is used on SDXC card (64GB and higher).
NOTE: exFAT can be used on flash drives or memory cards to transfer files larger than 4GB.
NOTE: MAC OS 10.6.2 or higher is required for exFAT file system. Some older operating systems must have a patch installed before they can use the exFAT file system.
SOLUTION 1 – Verify if minimum system requirement is met.
Urth card readers support Windows Vista, Windows XP SP2 and Windows 2000 SP4, Windows 7.
NOTE: No additional drivers need to be downloaded for the card readers as they are native to the above mentioned supported operating systems.
SOLUTION 2 – Verify the reader’s status under Device Manager.
STEP 1 – Connect the reader to the PC
NOTE: It is recommended that you plug your card reader to the back USB port on your PC to ensure that there is enough power from the USB port for the card reader to be detected properly.
STEP 2 – Check under Device Manager
1. Right-click My Computer.
2. Select Manage.
3. On the left pane, click Device Manager.
NOTE: The card reader will appear in two places: Disk Drives and Universal Serial Bus controls as USB Mass Storage. If there is a yellow exclamation point (!) or question mark (?) next to the device, try to refresh the drivers.
STEP 3 – Refresh the drivers
1. Right-click the entry with the error mark, select Uninstall.
2. On the top menu, click Action, and then click Scan for hardware changes.
STEP 4 – Verify if the reader is detected
1. Double-click My Computer.
2. Look for the card reader under Devices with removable storage.
SOLUTION 3 – Try other USB ports.
A yellow exclamation point (!) under Device Manager usually means that the device is not receiving enough power. If the reader is not receiving ample amount of power from the USB port, it may not function properly.
SOLUTION 4 – Change the drive letters
The speed rating measures maximum transfer speed for reading and writing images to and from a memory card, expressed as megabytes per second. However, video doesn’t need as big a data pipe because the video format is a smaller “fixed stream” that uses only a portion of the data pipe.
Unlike card write speeds that measure maximum performance, class ratings measure the minimum sustained speed required for recording an even rate of video onto the card. The class rating number corresponds to the transfer rate measured in megabytes per second. Class 2 cards are designed for a minimum sustained transfer rate of 2 megabytes per second (MB/s)1, while Class 10 cards are designed for a minimum sustained transfer rate of 10MB/s2.
What does this difference mean for me?
Rated Speed (e.g. 15MB/s, 30MB/s, etc.) is maximum speed of the card and also what you would expect to approximately see in typical usage of writing or reading files on the card. This measurement is pertinent to still photography, especially for taking pictures with high resolution and/or saving in RAW format where the files created are very large. The faster the card, the faster it can save the file and be ready to take another picture. You can really notice speed differences with high-megapixel DSLR cameras when using multi-shot burst mode.
Still digital images shot on high-megapixel cameras should utilize fast data throughput (a large data pipe), higher speed cards for improved performance. Higher speed cards can also improve how fast you can transfer the files to and from the card and your computer.
Speed Class is a minimum speed based on a worst case scenario test. The Speed Class is important for video mode or camcorders, where the device is actually saving a steady stream of data. The resolution and format of the video determines the amount of steady stream data. This translates to a minimum speed you need to guarantee that the video captured on the cards is recorded at an even, sustained rate with no dropped frames (which would result in lost data and choppy playback).
Compared to high-megapixel photography, video doesn’t need as big a data pipe because the video format is a smaller “fixed stream” that uses only a portion of the data pipe. But you do need a minimum guaranteed speed for the SDHC card that satisfies the requirement of the data stream. Your camera’s specifications should state the minimum SDHC Class Rating required.
Using a card without the proper class rating on a more advanced camera, such as a high-definition (HD) camcorder or Digital Single Lens Reflex (DSLR) camera with HD video record settings is likely to result in an error message indicating that video can only be recorded at a lower definition setting.
The current SDHC specification defines Class 2, 4, 6, 8 and 10 as follows:
|
Class |
Minimum Speed |
|
2 |
2MB/s |
|
4 |
4MB/s |
|
6 |
6MB/s |
|
8 |
8MB/s |
|
10 |
10MB/s |
UHS Speed Class was introduced in 2009 by the SD Association and is designed for SDHC and SDXC memory cards. UHS utilizes a new data bus that will not work in non-UHS host devices. If you use a UHS memory card in a non-UHS host, it will default to the standard data bus and use the “Speed Class” rating instead of the “UHS Speed Class” rating. UHS memory cards have a full higher potential of recording real time broadcasts, capturing large-size HD videos and extremely high quality professional HD.

SD/SDHC/SDXC memory card is write protected or locked
Solution 1 – Unlock the memory card.
There is a Lock switch on the left side of the SD card. Make sure the Lock switch is slid up (unlock position). You will not be able to modify or delete the contents on the memory card if it is locked.
Solution 2 – Toggle the lock switch.
If the lock switch is loose and moves easily It is likely the switch is sliding to the locked position as the card is placed in your host device. In this case the card will need to be replaced.
NOTE: If the above steps do not resolve the problem or if the lock switch is missing or broken, please contact Urth Support
