B+W XS-Pro Digital ND Vario MRC Nano Filter - 55mm

This filter allows you to adjust the neutral density from +1 f/stop to +5 f/stops.

Simply rotate the outer ring of the filter. The filter is marked to indicate the density levels.

This specific filter is for 55mm lens threads. You would need a step-up or step-down ring to adapt it, or purchase the filter in the correct size for your lens.

The XS-Pro Vario ND mount is extra-wide and designed to minimize vignetting, even with lenses as wide as 17mm on a full-frame camera. However, always test with your specific lens to be sure.

Use a soft, lint-free microfiber cloth to gently wipe the surface. The nano coating helps repel moisture, making cleaning easier.

Yes, it can be combined with other B+W ND filters. The ND Vario should always be used as the outermost filter when stacking.

MRC stands for Multi-Resistant Coating, which reduces reflections and protects against scratches. Nano technology refers to an additional layer that makes the surface hydrophobic, causing moisture to bead up and repel.

Yes, variable ND filters can produce an 'X' pattern or uneven darkening at extreme settings due to polarizing effects. This is normal for this type of filter and can often be mitigated by adjusting the filter's rotation or checking your camera's polarizer.

This is likely due to cross-polarization. Ensure that if your lens has a built-in polarizer, it is set correctly, or consider removing it if possible. The ND Vario filter itself can create polarization effects at extreme settings. Try adjusting the filter's rotation or your camera's polarization if applicable.

Ensure you are using the correct 55mm filter size and that the lens threads are clean and free of debris. Do not force the filter; if it binds, remove it and check for cross-threading or obstructions.

Variable ND filters can sometimes introduce a slight color cast, particularly at their extreme settings. Ensure the filter is clean and that your camera's white balance is set appropriately. For critical work, minor color correction in post-processing may be necessary.

While designed to minimize vignetting, extremely wide lenses or specific lens designs might still exhibit some darkening. Try zooming in slightly or check if the filter is correctly seated. Ensure you are not stacking too many filters.
