H&Y REVORING Variable Neutral Density and Circular Polarising Filters 37-49mm

The REVORING Variable ND + CPL 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.

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.
