REVORING from H&Y. Quite simply the world's most advanced step ring adapter ever made for a camera lens. Our cleverly designed and innovative variable blade technology gives any DSLR or Mirrorless camera system user the ability to use 1 single filter on multiple lenses, without the need for multiple step rings. So simple in its function, many have said: "why has this never been done before?".

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.

TIGHT GRIP

The major feature of the H&Y REVORING and REVORING Variable Neutral Density + CPL filter system is the ability to switch between lenses with a single filter; a simple twist, and away you go! However, when designing the variable retracting blades, we knew we had to match the strength of a regular filter attached to a lens. Coupled with the force of the retracting blades and independent threading, one final turn ensures that the REVORING is securely mounted onto your lens.

SAVE TIME

The REVORING and REVORING Variable ND+CPL will save you time when changing over filters for that perfect shot. For example, you might start off by shooting with a 24-70mm lens, and decide to switch to a 70-200mm, both of which may have a different thread size. You would either have to switch filters or adapt your filter using step rings, and we've all experienced this frustration, especially if you need multiple rings, or worse yet, they get stuck! With the REVORING, you just twist and remove from one lens, twist and mount to the other, it's that simple! 

DESIGNED FOR VIDEO AND PHOTOGRAPHY

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. 

GLASS & 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.
