H&Y Filters RevoRing Variable ND3-ND1000 & Circular Polarizer Filter (58-77mm)

H&Y REVORING Variable Neutral Density ND3 - ND1000 with built in Circular Polarizer Overview

• The REVORING Variable Neutral Density has a dynamic range of ND3 to ND1000, in photographic terms, this equates to 1.5 - 10 stops of light control!
• Hard Stop - The Variable Neutral Density ring will feature a hard stop at “MAX” preventing the user from going beyond the 10 stop position on the ring.
• Guide Pin - In addition to the Circular Polarizer inner ring, the Variable Neutral Density outer ring will also feature a guide pin, for improved control and functionality
• Focal Length Guide - The markers between “Min” and “Max" to reflect focal lengths and stops achieved using different lenses
• Each REVORING features unique self retracting blade technology with threaded ends to secure on the front of your lens 
• Each threaded end has been designed to overlap therefore completely removing any possibility of light leak. 
• All REVORING products are made using Architectural grade Aluminum, keeping it lightweight and tough. The anodised finish also protects the ring from corrosion when shooting outside in unpredicted elements. 

The REVORING Variable Neutral Density with built in Circular Polarizer combination has the benefit of being an essential tool for shooting both videos and stills. Once you have attached the REVORING to your lens, you have a wealth of dynamic range at your fingertips, with the added bonus of a Circular Polarizer which features Japanese Nitto polarizing film - offering up to 99.9% polarizing efficiency.

Almost 3 years of research and development, along with extensive field testing have been applied to bring the REVORING that much closer to reality. Our manufacturing process ensures that the materials used match the quality that customers have come to expect from H&Y. We are confident that image-makers across the globe will fall in love with this new concept and the REVORING systems will quickly become an indispensable partner for countless photographers and filmmakers.

Glass and Coating 

Anti-Fingerprint & Waterproof Nano-Coating Technology has been applied to the REVORING Variable Neutral Density + CPL filter system to protect the glass from the unpredictable factors that all photographers and filmmakers face when shooting outdoors. The coating helps with beading and any excess droplets can be easily removed with a lens cloth without the fear of eliminating any of the coatings and without leaving stubborn smears on the glass.

The German Schott B270® glass also includes Anti-Reflective coatings, which virtually eliminate all flare and reflections from the front and rear surfaces. This helps visible light to pass through the glass by removing unwanted reflections, giving the user the best possible light transmission (up to 97%), optimizing images for the sharpest possible outcome. Whether shooting at 16mm or 400mm, the glass and coatings used in the REVORING Variable Neutral Density + CPL filter system produce sharp images, even at light reductions of up 10 stops. 

Each side of the REVORING's glass has 9 layers of the above coatings applied.
