Related Questions and Answers

Q: 1. How thick is this filter?

A: I don't have this filter. Not sure why I was asked by BH to answer the question. Sorry.

Q: 2. Does it have positive stops, detents, at each of the stops?

A: The K&F Concept Variable Fader ND2-ND400 Filter (62mm) doesn't have detents; it has markings for the stops on the edge of the filter.

Q: 3. What size lens cap fits this?

A: A 69 or 70mm push on cap should fit.

Q: 4. Will these lens caps fit the 77 & 82MM Monfrotto Xume magnetic filter adapter sets?

A: Unfortunately no. The K&F Concept Soft Silicone Cap for Variable ND Filters (77mm) will only fit the K&F variable ND 77mm filters.

Q: 5. Are they hard stops?

A: Yes the stops are hard on the K&F Concept Variable Fader ND2-ND400 Filter. You can feel the filter pause as you rotate it past each mark so you know how many stops you are blocking.

Q: 6. Das it work with the 'Tiffen 82mm Variable Neutral Density Filter'? The output has more than 82mm

A: No, the K&F Concept Soft Silicone Cap for Variable ND Filters (82mm) does not fit the Tiffen 82mm Variable Neutral Density Filter.

Q: 7. Are these stackable? I'm looking for a ND+CPL

A: The K&F Concept ND & CPL Filter Kit for DJI Avata (3-Pack) are not stackable.

Q: 8. Does this create vignetting on the Voigt 40mm f/1.2 on a Leica M?

A: No, this filter should not cause vignetting on a 40mm lens.

Q: 9. I have a 32-64mm Fuji GFX zoom lens on a GFX 50R. Can this filter be used at full wide angle without vignetting with this lens? Thanks.

A: The B+W 77mm XS-Pro Digital ND Vario MRC-Nano Filter will not vignette the Fuji 32-64mm lens. This is because the front of the filter is 82mm. By having a larger front than the mount, it reduces the risk of vignetting on wide angle lenses.

Q: 10. What size lens cap fits this?

A: Unfortunately, the K&F Concept Variable Fader ND2-ND400 Filter (72mm) does not have front filter threads and is not designed for use with threaded lens caps.
