Extremely low light reflectivity performance
Optical performance of Celeste has improved by 33% in comparison to Zeta series. It is achieved by applying the newly developed 18-layer anti-reflection ”Super ZR coating”. Thanks to this coating technology light reflectivity level is less then Zeta UV – 0.2% against Zeta’s 0.3% (for Celeste C-PL: 0.3% against Zeta’s 0.6%).
Anti-Stain & Water Repellent Coating
Celeste filters adopt Anti-Stain Coating (ASC) that is layered on both sides of the glass for easier and more effective filter maintenance. Anti-Stain Coating is already being used in Kenko REALPRO series and got high valuation from photographers in all over the world.
Anti-Stain Coating allows a drop of water to maintain contact angle of over 100° and ensures long-time utilization compared to other brand filters coating that do not last long and come off in a quicker time.
Use the advantage of 1 more stop thanks to high transparency polarizing film, that transmits 25% more light than Zeta C-PL.
New sophisticated frame design
The new frame of the Celeste filter was developed after long and intensive research of other brand filter frames. As a result, the Celeste filter obtained several features that bring real advantages to the photographer.
The frame is slimmer than ZETA filter frame and the similar frames of other filter brands.
Celeste frame allows attaching lens caps safely.
Enlarged effective inner diameter due to improved retain ring prevents image from vignetting
