This 100 x 150mm Urth Reverse Graduated ND Plus+ Filter provides a fixed 3-stop light reduction in the top half of the filter, beginning at the center of the filter. The bottom half has no ND coating. The filter is ideal for capturing landscapes, seascapes, sunrises, and sunsets. When there's a defined horizon, like mountains or the sea, the filter helps you balance exposure and capture more detail within the highlights and lowlights.

The filter is 2mm thick and made with SCHOTT glass and 20 layers of nano coating. It's compatible with the Urth square filter holder system and most other 100mm square filter holders.

Q: 1. Will it fit inside of the Canon 200mm f/2?

A: If your camera lens has a diameter of 52mm, then it should fit....The lens mm diameter is compatible with any filter with the same mm diameter it claims to have. Hope this helps!

Q: 2. Will this fit Zeiss Batis 67mm lens with the hood ON?

A: I would say most likely no as I cannot use a hood with any of my lenses when using this filter.

Q: 3. does this affect colors in any way? does it desaturate colors as those cheaper ND filters?

A: Hi my friend, this is a nice piece of glass, for Shure you will have some impact in your color results. Minors, but they will be there. No free lunch. To be a variable in one piece you sacrifice something. Specially because it is affect the luminance that is very very important to color. But don't worry, you can easily fix at post, for video or photography. Best

Q: 4. with an ultra-wide angle lens (i.e. Canon 16-35mm F4L with a full frame camera), do you get the dreaded X show up and if so at what density does it show up?

A: The X you can sometimes pick up in the image with a variable ND filter is caused most of the time by variable ND filters that go over 7-8 stops and lower quality ones.The B+W filter is fine. The one thing you might pick up is when set to the widest setting on that lens, 16mm you might pick up some vignette. And that is going to happen with that lens with most filters because of how wide it can go. The filter is designed with a thinner frame so it should be somewhat minimal.

Q: 5. This filter has a 72mm filter thread. So, is it same to assume that a lens cap will also be 72mm?

A: That's correct, Lenscap is 72mm. This filter lives on my camera almost permanently. Worth every cent!

Q: 6. The description says that this filter features a thin, oversized mount which helps to reduce the likelihood to vignetting when used with wide-angle lenses. To use this filter with a smaller diameter lens, what step down ring size would I have to use to be able to use it on a smaller lens diameter - - 77mm or 82 mm to hold this filter?

A: The size step-up ring that would be required for use on your lens would depend on the filter size of your lens. Unfortunately, you did not list the lens you own or its filter size. As the B+W 77mm XS-Pro Digital ND Vario MRC nano Filter has 77mm rear filter threads, you would need a step-up ring that has 77mm front filter threads. If you need assistance with locating the proper ring for your equipment, you would have to send an e-mail to askbh@bandh.com with the above information and we will assist you with your inquiry.

Q: 7. Does this filter have front threads so I can attach it to a matte box or an additional filter? Thanks!

A: Yes it does have a front thread of 77mm.

Q: 8. Will I be able to use my LX100 auto lens cap or JJC auto lens cap with this?

A: You will be able to use lens caps with this filter, yes.

Q: 9. I have a UV protective filter, Can i use it in addition to a Polarize filter? Stack all 3?

A: It's typically advised you don't stack filters due to diminishing transmission and risk of unwanted glare/artifacts/color-shifting/cross-polarization.

Q: 10. Can this filter be used on wide angle lenses for example Sigma 10-20mm? I have tried cheaper alternatives with extremely poor results. Uneven darkening and camera (Pentax K-7) metering failing resulting in gross underexposure.

A: I've tried only 2 variable ND filters: this B+W one and a similar one by Genustech. Non-variable ND filters have fewer problems. From what I've read, most of the variable ND's, like the Genustech, have the shortcomings you describe. This B+W does not. It is consistent in how it transmits light across the whole filter without the usual cross artifact that darkens the image unevenly. I use this filter mainly for video with large sensor cameras; my only qualm with the filter is that it doesn't get dark enough for very bright scenes and that's partly due to my lowest ISO rating being 400. So I have to stop down the lens anyway, just not as much, but more than I'd like to. I can't vouch for no vignetting on a 10mm super wide lens. I get no vignetting at 17mm focal length on my 17-55mm Nikon zoom. B+W's engineering and build quality is usually superior to the rest.
