REVORING: A Variable Step Ring for your Camera Lens Filters

I haven't seen this posted here but this is an interesting ring for your filters. It was on Kickstarter but the campaign has ended has now moved to Indiegogo.

The REVORING is a true first in the image-making world. Its revolutionary design overcomes the need for multiple filters and step-up rings, saving photographers and filmmakers both time and money.

REVORING: The last word in filter adapters
The REVORING arrives as a completely new type of filter adapter. With its patent pending variable and tough retractable blade technology, it can fit any lens with filter thread sizes between 37 - 49mm, 46mm - 62mm or 67mm - 82mm, accommodating either 52mm, 67mm or 82mm screw-in filters for the sizes available at launch. This versatility negates any need for photographers, cinematographers and content creators to carry multiple step-up rings, which can make for messy kit bags and adding unnecessary extra weight.

REVORING Variable ND + Circular Polariser combination
In addition to the standard REVORING, H&Y’s Kickstarter campaign includes another brand new REVORING which combines the REVORING’s adapter technology with the brand’s market-leading Variable Neutral Density & Circular Polariser combination filter. This heady combination creates a truly unique and complete product for image-makers everywhere.

Completely eradicating the need to invest in multiple filters for each lens or multiple step rings to adapt existing filters, the REVORING Variable ND + Circular Polariser combination system will adapt to fit a wide range of lenses, improving handling and boosting workflow speed to the next level.

H&Y’s REVORING Variable ND + Circular Polariser combination will quickly become an essential tool for shooting both moving and still images, giving a wealth of dynamic range to the user’s fingertips with the added bonus of a high-quality H&Y Circular Polariser onboard.

The REVORING’s variable neutral density offers an incredible dynamic range of ND3 to ND1000, which equates to a minimum of 1.5, through to 10 stops of light control. However, due to the vast range, the stops achieved will vary based on different 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.

Japanese Nitto polarising film has been applied to produce the Circular Polariser section of the filter, which offers up to a near-comprehensive 99.9% polarising efficiency.

Market Leading Quality Meets World-Class Innovation
Key to the REVORING’s unique design is in the innovative, retractable & variable diaphragm. This precision-engineered feature allows the REVORING to make 1 filter applicable to multiple lenses, and with the potential for an expansive 4 size options, filter thread sizes from 37mm through to 95mm are all covered.

The REVORING has been manufactured entirely from architectural building-grade 6063 aluminum, making it incredibly strong and lightweight. Finished in a matte black anodised coating, further protecting it from adverse weather conditions, the REVORING is truly a ‘go-anywhere’ solution that will serve for years to come.

Anti-Fingerprint & Waterproof Nano-Coating Technology has been applied to the REVORING 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 coatings used in the REVORING produce sharp images, even at 10 stop exposures.
