This 100 x 150mm Urth Soft-Edge Graduated ND Filter 100x150mm 3-Stopfrom Urth Soft-Edge Graduated ND Filter 100x150mm 3-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 3-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 100mm Filter System, plus other 100mm-wide filter holder systems.

Related Questions and Answers

Q: 1. Will this filter cause vignetting on the Canon RF 35/1.8 (using a Canon RP body)?

A: This filter would be specific to wide angle lenses, so it would not vignette on a lens like the Canon RF 35mm f/1.8.

Q: 2. Will it fit in Lee 100 and Nisi V6 filter holders?

A: Yes, they are all 2mm thick and will work with each other.

Q: 3. 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: 4. 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: 5. 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: 6. is this filter compatible with nisi v5 100mm system?

A: Yes the B+W 100 x 100mm XS-Pro MRC-Nano 803 Solid Neutral Density 0.9 Filter is compatible with the NiSi V5 Pro 100mm Filter Holder Kit at 100mm x 100mm, and 2mm thick.

Q: 7. 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: 8. Will this work with Panasonic Lumix G Vario 7-14mm f/4 ASPH. Lens?

A: Yes, the Panasonic Lumix G Vario 7-14mm f/4 ASPH. Lens should be compatible for use with the Tadashi Solid Neutral Density 0.9 Filter for Select SLR Fisheye Lenses (3 Stop).

Q: 9. Preventing light leaks: Gasket available? Seal built in to holder?

A: you can try this BH #FOFG3P85

Q: 10. 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.
