B+W Premium 52mm MRC Clear XS-PRO Filter

Description

The
B+W 52mm XS-Pro Clear MRC-Nano 007 Filter
is a simple, clear filter with a 1x filter factor and is designed to provide general protection for your lens. This optically clear filter does not affect overall image quality while helping to reduce dust, scratches, moisture, and other elements from damaging your lens. To prevent internal ghosting and reflections while providing over 99.8% light transmission, each glass surface includes multiple layers of anti-reflection coating. This Multi-Resistant Coating (MRC) also offers greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. The Nano coating associated with XS-Pro filters provides an additional eighth layer over the MRC, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.
B+W filters are constructed from Schott glass for increased optical clarity and color fidelity. This filter features a thin brass filter ring to minimize the potential for vignetting while enhancing durability and jamming prevention. To further reduce the possibility of vignetting while using this filter, the filter ring's outside diameter is slightly larger than the actual thread size. This may prevent the use of some lens manufacturer bayonet hoods.

This filter was installed on one of my wife's lenses that saw less than 200 shots, and spent it's life under the lens cap.  They currently retail for .99.  Why pay that when you can get this one for only with free shipping?
