Kenko Zeta Protector Filter

This is the ultimate in clear filters. It will not affect the color balance or performance of your lenses in the slightest. However, constant use will protect your valued lenses from expensive front element damage which could be caused by dirt, knocks or scratches 

The Zeta series debuted in 2009 after a long, exhaustive effort by Kenko to offer the highest end filters. Adopting the newly developed the ZR coat, which achieves one of the world’s best surface reflectivity levels of 0.3% or less (or 0.6% or less with C-PL of low-temperature multi-coat specification), the Zeta series cuts reflection on the filter’s glass surface to eliminate flare and ghosting. All Zeta filters use glass material of the highest quality, and their frame, which retains the filter glass, ensures the maximum degree of flatness.
