The 007 Clear filter meets the needs of many photographers for pure lens protection. Its sole purpose is to keep dirt, sand, and moisture off the front lens element. The hydrophobic coating reduces the adhesion tendency of dirt particles and water droplets. The advantages are extremely easy cleaning and maximum reduction of reflections.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. B+W filters not only cost just a fraction of the price of a new lens but they are also easier to clean.They can remain in front of the lens permanently as they are absolutely color-neutral, highly transparent and, thanks to the B+W Mrc coating, have an extremely low reflection. The optical information remains unaffected when it reaches the image sensor (or film).
