The Kenko Zeta filter with 'ZR Anti-Reflective Coating' is the ultimate filter for use with Digital Single Lens Reflex Cameras. Water Repellent - Scratch Resistant - Easy to Clean Newly designed innovative ZR (Anti-reflective) coating makes reflection rate less than 0.3% of single surface of the glass (Less than 0.6% with Wide Band C-PL). ZR coating also creates Water Repellent and Scratch Resistant glass surface to make filter maintenance very easy. Low profile and extremely thin (4mm) filter frame is fully compatible with super wide-angle lenses. This innovative coating will not interfere with any color or light transmission. Reflections are eliminated by allowing light to enter the filter at virtually any angle. This filter will produce superior results and can be used with any type of lens (wide angle to telephoto).
