H&Y RevoRing Variable ND3-ND1000 and CPL Filter with 67-82mm Variable Adapter

The H&Y RevoRing VND+CPL combines the RevoRing's variable adapter technology with the H&Y's market-leading Variable Neutral Density & Circular Polarizer combination filter. This impressive and useful combination creates a truly unique and complete product for image-makers everywhere. Completely removing the need to invest in multiple filters for each lens or multiple step rings to adapt existing filters, the H&Y RevoRing VND+CPL system will adapt to fit a wide range of lenses, improving handling and boosting workflow speed to the next level. With its patent-pending variable and tough retractable blade technology, it can fit any lens with filter thread sizes between 67 - 82mm.H&Y's RevoRing VND+CPL Variable ND + Circular Polarizer combination will quickly become an essential tool for shooting both moving and still images, giving a wealth of dynamic range at the user's fingertips, with the added bonus of a high-quality H&Y Circular Polarizer onboard. The RevoRing VND+CPL's variable neutral density offers an incredible dynamic range of ND3 to ND1000, which equals 1.5 to 10 stops of light control. Markers on the VND ring will indicate the maximum ND allowed for a given focal length. Full details can be found on the H&Y website, and also in the product guide, which will be included with every RevoRing VND+CPL.High-performance Japanese Nitto polarizing film has been applied to produce the Circular Polarizer section of the filter, which offers up to an impressive 99.9% polarizing efficiency. A hard stop at the Min and Max point on the VND ring, restricts the movement of the VND filter from going beyond the Min/Max range. Guide pins on the VND and Circular Polarizer make it easy to independently adjust each control easily and conveniently.Anti-Fingerprint & Waterproof Nano-Coating Technology has been applied to the RevoRing VND+CPL to preserve 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 coating, which virtually eliminates 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 9 layers of coatings (on front and back surfaces) used in the RevoRing VND+CPL produce sharp images, even at 10 stops of ND.Note: the stops achieved will vary based on different focal lengths.
