Kenko Zeta Ultimate ND4 77mm

This ND4  filter reduce the amount of light entering the lens so wider apertures can be selected, which is perfect for portraiture to reduce depth of field. Subject appears crisp and clear while the background becomes a soft blur. Also widely used for photographs of waterfalls and other nature scenes to emphasize movement.

The ND4 reduces light entering the camera lens by the equivant of 2 stops.

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. 

Wide-Band Polarizing Film 
The Kenko Zeta wide-band polarizing film transmits light more evenlyacross the visible spectrum to give a more neutral color balance than traditional circular polarizing filters provide.
