B+W UV-FILTER 77MM MRC NANO MASTER

They can be left in front of the lens at all times because they are absolutely color-neutral, still extremely transparent and extremely low-reflection thanks to the B+W MRC or B+W MRC nano coating. The optical signal reaches the image sensor (or film) unaffected. With the extremely clear and highly transparent B+W protective filters, no extension factor needs to be taken into account.

Protective filters play a particularly important role in digital photography. Greater depth of field due to small sensors increases the effect of front lens contamination on image quality. Especially with zoom lenses with a lower light intensity, fingerprints have a significant effect on sharpness. Frequent cleaning of the front lens can not only leave scratch marks, but can also transport dirt particles or moisture on the frame edge into the interior of the lens system.
