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.


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.


Anti-Fingerprint & Waterproof Nano-Coating Technology has been applied to the REVORINGVariable 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 REVORINGVariable 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.  


As a result of continued tests and working on feedback from our ambassadors, we are excited that we can already announce the following features which will be included in the final product;

  •  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 – There will be a redesign of the Variable Neutral Density markers between “Min” and “Max” to better reflect focal lengths and stops achieved using different lenses


Space is a commodity for photographers and filmmakers! Let’s face it, we are always on a quest for new bags and backpacks, with hundreds of pockets and compartments to carry all the latest gadgets and accessories launched every year. But, what if all you need to do is simply reduce the amount of gear you carry while achieving the same or greater level of productivity? The REVORING saves you the need to carry multiple filters and step rings, meaning you can pack lighter and more efficiently for your travels.  


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! 

Our US Ambassador, David Akoubian, got to play with a handful of our REVORING samples and had fun in showing just how easy it is to switch between lenses, saving him time when out shooting.      


Not only will the REVORING save you space and time, it will also save you money! You no longer need to buy multiple filters or step-up rings for all of your lenses. Instead, choose a REVORING suitable for your lenses, add 1 filter, and you are good to go!   

Philip Bloom has had hands-on with the REVORING. Watch his video, where he covers the many features it has, including just how much money it can save you!


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!
