B+W 77mm XS-Pro Digital ND Vario MRC-Nano Filter
Key Features
  • Variable 0.3-1.5 Neutral Density Filter
  • Reduce Exposure by 1-5 Stops
  • Darkens Entire Image
  • Greater Control Over Exposure Settings
The B+W 77mm XS-Pro Digital ND Vario MRC-Nano Filter is a solid variable neutral density filter providing an exposure reduction of 1 to 5 stops. The 0.3 to 1.5 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is also visually demarcated with dots that represent different density values.

B+W 66-1072522 Overview

The B+W 77mm XS-Pro Digital ND Vario MRC-Nano Filter is a solid variable neutral density filter providing an exposure reduction of 1 to 5 stops. The 0.3 to 1.5 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is also visually demarcated with dots that represent different density values.

The Multi-Resistant Coating (MRC) is both an anti-reflection coating as well as a protective surface. It helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, it offers greater protection to the filter substrate and stays cleaner for longer than uncoated filters. The Nano coating associated with XS-Pro filters provides an additional eighth layer over the MRC, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

B+W filters are constructed from Schott glass for increased optical clarity and color fidelity. This filter features a thin, oversized mount which helps to reduce the likelihood to vignetting when used with wide-angle lenses. The filter ring is made from brass for durability as well as jamming prevention.

question

The description says that this filter features a thin, oversized mount which helps to reduce the likelihood to vignetting when used with wide-angle lenses. To use this filter with a smaller diameter lens, what step down ring size would I have to use to be able to use it on a smaller lens diameter - - 77mm or 82 mm to hold this filter?
Asked by: Anonymous
The size step-up ring that would be required for use on your lens would depend on the filter size of your lens. Unfortunately, you did not list the lens you own or its filter size. As the B+W 77mm XS-Pro Digital ND Vario MRC nano Filter has 77mm rear filter threads, you would need a step-up ring that has 77mm front filter threads. If you need assistance with locating the proper ring for your equipment, you would have to send an e-mail to [email protected] with the above information and we will assist you with your inquiry.

This filter provides a hard stop at the beginning and at the end of the stop rotation. Please keep in mind there is no D-click between stops.

question

with an ultra-wide angle lens (i.e. Canon 16-35mm F4L with a full frame camera), do you get the dreaded X show up and if so at what density does it show up?
Asked by: Khurram
The X you can sometimes pick up in the image with a variable ND filter is caused most of the time by variable ND filters that go over 7-8 stops and lower quality ones.The B+W filter is fine. The one thing you might pick up is when set to the widest setting on that lens, 16mm you might pick up some vignette. And that is going to happen with that lens with most filters because of how wide it can go. The filter is designed with a thinner frame so it should be somewhat minimal.

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.
Asked by: Bill
I would expect vignetting, if mounted with the proper ring size. You can try this one with a larger ring size and step down ring or take a dedicated 6x / 3x ND, but that obviously takes away the vario part...

question

How can we clean the inside of the filter?
Asked by: NICHOLAS
I must admit in a career of photography never needing to clean the inside of a rotating Polarizer. If for some really reason you actually had to clean the inside, that would be a task for a professional camera technician. No user serviceable parts are here.

question

I regard to the question about the front threads:Note that the specs supplied by B&H say that the mfg has not provided that info. Upon receiving this filter hoping I could add the the Nikon R1C1 flash system to it (the reason I bought this unit instead of others that had no front threads) I can tell you that the threads are well over 77MM wide. I should have figured that out when the description states the filter is oversized.
Asked by: Anonymous
The front threads are approximately 81mm on the XS-Pro 77mm Digital ND Vario. While it will not be possible to use the R1-C1 mounted on this filter, the flashes on the R1-C1 separate off the ring and the system comes with stands. You could mount the flashes onto stands and ultimately a tripod and light the subject in this manner, and just use the system without having the flash on the camera.
