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.

<Key Features>
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. This filter will produce superior results and can be used with any type of lens (wide angle to telephoto).

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. 

Ultra Thin Frame 
The glass of this filter is set in a precision machined frame and attached using Retainer Ring Mount Technology giving this filter an unsurpassed durability. An ultra thin frame also makes it wide-angle lens compatible. 

L41 Super UV Cut Glass 
The Zeta UV L41 filter absorbs up to 410nm of ultraviolet rays. Normal UV glass has a slight yellow tint, but the L41 is perfectly clear due of the use of a high-performance glass.

General care and handling of the photographic filter

1. Use filter carefully and always keep it clean. When cleaning use cleaning tissue or cleaning cloth. But before that remove as much dust and dirt as possible from the lens with a blower or brush.
2. Avoid unnecessary cleaning of your filter.
3. Filter is made of glass. When it is broken glass fragments may injure.
4. Do not disassemble filter by yourself.
5. When the filter is not attached to the lens, store it away from sharp objects. They may damage the filter glass.
6. Keep filter away from children.
7. Keep filters in plastic hard-sided case or filter pouch.
8. Keep filters dry and away from direct sun light.
9. Avoid storage in high humidity environment. Moisture drops due to the high humidity or dew on the filter can burn the coating and create traces on the glass surface that can be hardly wiped off.
