This 75 x 100mm Urth Soft-Edge Graduated ND Filter 75x100mm 1-Stopfrom Urth Soft-Edge Graduated ND Filter 75x100mm 1-Stopis a rectangular filter that darkens specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the remainder of the image area. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. This soft-edge design is appropriate for use with images that feature a prominent horizon, or any soft transition between sky and land, like wooded landscapes and cityscapes. This filter provides a 1-stop reduction in light from entering the lens and does not affect the coloration of the image.

Constructed from Schott optical glass for clarity and color fidelity, this filter features 20-layers of nano multi-coating to reduce potential glare and lens flare. This filter is 2mm thick and fits the Urth 75mm Filter System, plus other 75mm-wide filter holder systems.

Related Questions and Answers

Q: 1. will this filter vignette with the Canon EF 16-35mm F4L lens?

A: I'm a Nikon shooter, so my answer is in that context. I no longer have my Nikkor 17-35, so the best other lens I could test it on is my Nikkor 12-24, which is a DX lens (also a 77mm diameter). Yours, however, is an FX lens, so I don't know how that may affect the comparison. I tested it on the D800, in full format mode. I noticed the beginning of vignetting when the focal length was 19mm. I did it a few times, and that was consistent.So, if this is in any way accurate, you can probably expect to lose a few mm of focal length at the3 wide end when you use this filter. I don't know if this filter is made in a thinner version for wide angle use. Hope this helped.

Q: 2. Has anyone used this filter with the DJI X5 camera? If so, how is the color fidelity? Is there any specific color cast? Thank you.

A: B+W make very high quality filters. This will give you a great performance when used on lens with the X5.

Q: 3. When stopped to the highest setting (5 stops) does the image degrade (sharpness, cross hatching)?

A: I've shot extensively with the 95mm, 72mm, & 67mm versions. You don't get any cross-hatching, but a definite vignette in the corners toward the 5 stop range when shooting photos. Video is not an issue as it crops to 16:9. Other than than, negligible colour cast & no sharpness issues.

Q: 4. 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: 5. Is this a hard stop filter where it goes from 2 to 5 and then it can't proceed further ?

A: The rotation of the filter is smooth. It does not click as you rotate it. It also stops rotating once you reach the maximum or minimum density.

Q: 6. Can other filters screw on to the Nano filter to stack filters?

A: Unfortunately this filter is too thin to stack any more filters on top of it.

Q: 7. Can 72mm XS-Pro Digital ND Vario MRC-Nano be able to fit Sony FE 16-35mm F4 ZA with XS-Pro UV or UV + Polarizer without Vignette?

A: If filter diameter on your lens is 72 mm there will be no vignett with any 72 mm filter. Vignetting only occurs if the lens does not match crop factor for camera.Hope this helps.

Q: 8. Is this filter compatible with Lee Filters Foundation Kit (Standard 4x4") B&H # LEFK ?

A: Yes, this filter will fit with the Lee Filter Foundation Kit.

Q: 9. 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.

Q: 10. I use the NiSi 100mm Filter Holder for Nikon Z 14-24mm f/2.8 S Lens. Is this filter compatible.with that holder?

A: Yes, you can use the NiSi 100 x 100mm Explorer IRND 3.0 Filter with the NiSi 100mm Filter Holder for the Nikon Z 14-24mm f/2.8 S Lens.
