B+W Master MRC Nano Clear 007 77mm

MRC Multi Resistant Nano Coating
Each side of the filter has 7 anti-reflection coatings plus a strengthened protective Nano outer coating. The Nano coating creates a beading effect with water which has a repellent effect (also with dirt), so the filter is easier to clean and reduces fogging. MRC coating ensures maximum reflection and stray light reduction (residual reflection of just 0.5%). This ensures brilliant colours and high contrast, and the elimination of ghost images caused by back reflection from the camera sensor

Precision engineered mount
The 3mm deep brass mount is made on a CNC milling machine. The filter glass is held securely but without tension by a threaded retaining ring. There is a front thread. Black hard-chrome plating with a matt black inside surface and engraved markings ensure long service.
