The 46mm Urth ND Lens Filter Plus+ 46mm 3-Stopfrom Urth ND Lens Filter Plus+ 46mm 3-Stopprovides a fixed 3-stop light reduction for better control with long exposure and depth of field techniques. With less light entering your camera, you can also use wider apertures for a beautiful shallow depth of field effect without overexposing images. Cinematographers can use the ND8 Filter Plus+ to create more cinematic effects in low light without losing quality or overexposing the shot. The Plus+ range features 20-layers of nano-coating, which provides easier cleaning and better protection against water, oil, and scratches. These layers also provide a higher maximum light transmission and a more consistent transmission curve for truer light reduction.

The filter is double-threaded for stacking filters or using screw-mount lens caps.

The fixed ND8 Filter Plus+ lets you capture motion blur and depth of field effects in low light. The filter is great for landscape photography and cinematic effects in videography.

The filter's German B270 SCHOTT optical glass is coated with a 20-layer nano-coating for truer light transmittance, better protection, and easier cleaning.

The consciously designed ultra-slim rim avoids vignetting and our durable magnalium is guaranteed for life.

Beautiful depth of field with wider apertures.

Q: 1. Will this fit in the 52mm filter holder slot for Nikon 200mm f2 or 200-400 f4 lenses?

A: The Urth 52mm ND64 1.8 Lens Filter Plus+ (6-Stop) may or may not fit the Nikkor 200mm f/2 or Nikkor 200-400mm f/4 lens, but the only filters guaranteed to fit are Nikon filters.

Q: 2. 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: 3. Does B+W 82mm XS-Pro Digital ND Vario MRC-Nano Filter cause any vignetting and X-shadow at 15 mm end (Canon 15-35 mm RF 2.8 lens)? Thanks

A: There is a possibility of slight vignetting at 15mm.

Q: 4. anybody using this filter? Have you had any problems?

A: I've had it for a few months. Bought it because the Bower 95mm was just awful.... you get what you pay for! Personally, I've noticed no X pattern on this filter at all -- even at its highest level of filtering. I've not noticed too much of a color shift either....

Q: 5. Does the front filter thread rotate when changing ND Amount? Looking to add a step up ring and go to a matte box.

A: Yes, the front threads on this filter are a 86mm size.

Q: 6. 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: 7. Do these have stops at min/max?

A: According to Urth, the Plus+ ND filters have hard stops at maximum and minimum stops.

Q: 8. 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: 9. What is the widest focal length this can be used on with no vignetting?

A: I have the filter on my 24-70mm/f2.8 lens. So the widest is 24mm. I did not see any vignetting. I am very happy with this filter.

Q: 10. Hello. I purchased this filter but I am having difficulty working out the stop values for each dotted marker increment on the outside ring? I assume the first dot is 1 stop and last dot is 5 stops. If you divide the rest by 1/3 stop or 1/2 stop, then it does not work out mathematically. Any tips or manuals for this lens?

A: Unfortunately, this is typical of most variable neutral density filters across the spectrum. The markings between the minimum and maximum do not accurately indicate a precise number of stops, and even brands than mark them with ND factors miss the mark significantly; some brands are off by 1/3~2/3 stops with engraved filter factors. While I am not familiar with the physics and/or engineering reason for this, a commonly accepted technique is to adjust the camera settings first and then dial in the VND filter factor. This might be hard/impractical with longer shutter speeds though, so preemptive testing might be necessary.
