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.
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.
