The B+W 95mm XS-Pro Vario Neutral Density MRC Nano Filter provides professional photographers with adjustable density control for precise exposure management. This 95mm diameter filter offers variable neutral density adjustment from +1 to +5 stops, allowing photographers to manipulate light intake across diverse lighting conditions while maintaining image quality. The filter features MRC nano coating technology, which creates a protective layer harder than glass with water and dirt repellent properties. This nanotechnology coating exhibits a lotus effect for improved water beading and simplified cleaning, while providing enhanced scratch resistance for long-term durability. The XS-Pro mount incorporates an extra-wide design that minimizes vignetting concerns with most 17mm lenses on full-frame camera bodies. The filter's construction supports combination with additional fixed-value ND filters when positioned as the outermost element in filter stacks. The adjustable density mechanism includes an index setting for precise control between density levels, enabling photographers to achieve creative effects such as motion blur in bright conditions or shallow depth of field with wider apertures. Professional photographers value this filter for its reliable performance in landscape, architectural, and portrait photography applications where precise exposure control is essential. The robust build quality ensures consistent optical performance while the nano coating maintains surface integrity through regular use and cleaning cycles. Compatibility extends to various professional lens systems within the 95mm filter thread specification, though users should verify performance with specific equipment configurations. This filter represents a versatile tool for photographers requiring dynamic light control without compromising optical clarity or color accuracy in their final images.
