77mm XS-Pro Vario Neutral Density Filter

The B + W Filter Company 77mm XS-Pro Vario Neutral Density MRC Nano Filter provides adjustable density control from +1 to +5 stops. It is built for photographers who need to manage exposure across changing light without swapping fixed filters. The XS-Pro mount includes an index setting for precise adjustment. This filter serves as a versatile front element for creative exposure control.

Adjustable density with MRC Nano coating

The filter covers a density range of +1 to +5 stops, offering headroom for bright conditions and motion-blur effects. It is designed to be the outermost filter when stacked with additional B+W fixed ND filters for even higher density. Multi-Resistant Coating with Nano Technology protects the glass and simplifies cleaning. The coating also helps maintain image quality during extended use.

Extra-wide mount to reduce vignetting

The XS-Pro Vario ND mount features an extra-wide design that helps avoid vignetting with most 17mm lenses on full-frame bodies. Photographers should test with their specific lens and camera combination to confirm results. The 77mm thread size fits compatible lens diameters directly. It frees up the need to carry multiple fixed-density filters for variable lighting.

Questions about this item

Will the 77mm XS-Pro Vario ND cause vignetting on my 17mm full-frame lens?

The extra-wide XS-Pro mount is designed to avoid vignetting with most 17mm lenses on full-frame bodies, but testing with your specific equipment is recommended to confirm results.

How do I verify the density stops are engaging correctly on the XS-Pro mount?

Rotate the filter ring until the index marker aligns with a stop value between +1 and +5; the viewfinder or live view should darken smoothly at each step without hard stops beyond the marked range.

Does the box include a protective case or do I need to buy one separately?

The filter ships with a protective case; no separate purchase is required for storage.
