This 75 x 85mm ND Filter Plus+ from Urth darkens the entire image area, allowing motion blur to be captured and greater creative control over depth of field. This ND8 filter reduces exposure by 3-stops, allowing the desired settings to be maintained in overly bright conditions to create dramatic motion blur and shallow depth of field. This filter is fabricated from German Schott glass for true light transmittance and supreme image sharpness. The filter surface features a 20-layer nano-coating, providing neutral color balance, reduced lens flare and ghosting, and protection from smudges and scratches.

Compatible with the Urth 75 x 85mm Square Filter Holder System and most 75mm square filter holders.

Q: 1. 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: 2. 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: 3. The image looks extremely thick, is this filter thin?

A: The B+W 77mm XS-Pro Digital ND Vario MRC-Nano Filter is 12.3mm (0.48 inches) thick.

Q: 4. Hi there Is this ND compatible to use with Sony Fe 400/2.8—i.e. internally? Thanks

A: No, the B+W 40.5mm XS-Pro Digital ND Vario MRC-Nano Filter would not be compatible for use with the Sony FE 400mm f/2.8 GM OSS Lens. While the Sony FE 400mm f/2.8 GM OSS Lens does use 40.5mm filters, the B+W 40.5mm XS-Pro Digital ND Vario MRC-Nano Filter would be too thick for usage in the drop-in filter holder.

Q: 5. Do you think I would get vignetting if I used this on a 10mm with a 77mm filter thread and a step up ring?

A: I suspect you would get 'some' vignetting, but don't have actual experience with this combination.

Q: 6. How smooth is the rotation ring?

A: The rotation ring on this filter moves easily and smoothly--much better than most variable ND filters.

Q: 7. Can someone confirm if this 95mm still allows for the Sony 28-135mm factory hood to be mounted with the filter on? Thank you!

A: It does not allow for the factory hood to mount - it is too big for the hood to slide over the filter.

Q: 8. Does this filter come with an 82 mm front cap?

A: Received only the filter without cap

Q: 9. Has anyone tried the Variable 82mm on a sony 16-35GM2.8? I want to know if you saw any vignetting or any issues with it. I know the 24-70gm also has the same filter thread so I was wondering just how wide you can go with the filter beefore vignetting.

A: Today's Polarizers from quality manufacturers are all made to be thin to avoid vignetting on wide lenses. This one from B+W has the coveted Thin Brass Filter Ring. You will be good.

Q: 10. 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
