Fingerprints, smudges, and of course scratches conspicuously diminish the imaging quality of lenses, and in the worst cases make the purchase of replacements necessary. A high quality glass filter in front of the lens provides additional protection.

For a long time, the user could choose between a UV or skylight filter, since both have relatively little effect on the imaging performance of the lens. The filtering effect of the new B+W Protective Filter 007 Clear, on the other hand, is completely neutral: its only task is the protection of the front lens, with no change in imaging quality or speed of the lens.

The new filter offers high, even transmission in the visible range, since it is made of a very clear, colorless special glass (B - 270 by Desag); the surface is finely polished for the highest optical performance level, and also has the innovative B+W hydrophobic multilayer (Multi Resistiant Coating).

With this coating, the tendency for moisture, dust, and other dirt particles to adhere is significantly reduced, and the scratch resistance of the surface is significantly increased, thanks to the improved hardness of the outer layer.  In actual use, the B+W MRC coating not only guarantees the maximum in reflection reduction, but also very simple cleaning and care of the filter.
