Kenko Zeta 62mm ZR SMC Wideband Circular Polarizer Lens Filter KZ62CRPL Wide-Band Polarizing Film: The Kenko Zeta wide-band polarizing film transmits light more evenly across the visible spectrum to give a more neutral color balance than traditional circular polarizing filters provide. Ultimate Color Enhancement: C-PL filters allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer with better contrast. ZR ( Zero Reflection ) Super Multi-Coating: 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. Ultra Smooth Surface - Nano Glass Technology: Our Nano Glass Technology creates an ultra smooth surface from the finest particles of glass, making it stain and scratch resistant without any effect to the image.
