UV and Protection
Active photography puts a great demand on both cameras and lenses. It makes sense therefore to use a B+W filter to protect your delicate front lens element against the elements such as blowing sand and dust, fingerprints and splashing water. They are absolutely color-neutral, highly transparent and, thanks to the B+W MRC coating or B+W MRC nano coating, have an extremely low reflection. The optical information remains unaffected when it reaches the image sensor (or film).
The 007 Clear filter acts as the ultimate lens protector. Its sole purpose is to keep dirt, sand, and moisture off the front lens element. Due to hydrophobic coating the adhesion tendency of dirt particles and water droplets is reduced. The advantages are: extremely easy cleaning and maximum reduction of reflections.
The classic amongst the B+W protection filters blocks the annoying UV component of daylight. Invisible UV light is more intense in pure sea air and in high mountain regions and can cause blurring and a blueish cast.
