ERGONOMICS

Editor’s Note: both the basic RevoRing and the RevoRing with integrated Variable ND + CPL will also be available in two additional sizes through Kickstarter campaign: 52mm (supporting lenses with filter threads ranging from 37mm to 49mm) and 95mm sizes (supporting lenses with filter threads ranging from 82mm to 95mm).



Here’s another look of the four RevoRings, with filters attached onto the standalone RevoRings. The standalone 46mm to 62mm RevoRing has a 67mm H&Y HD MRC Slim 4 Stop ND filter attached, while the standalone 67mm to 82mm RevoRing has an 82mm H&Y MRC C-Polarizing Filter attached.

Here’s a closer look at the standalone H&Y RevoRing from the attachment side. The 67mm to 82mm variant is pictured above, but the 46mm to 62mm version is functionally identical. What makes the H&Y RevoRing Filter System is the adjustable, spring-loaded “Turn, Hold, and Release” attachment system.



As you can see, the front ring is knurled while the rear ring is ridged. In order to attach a RevoRing onto one of your lenses, simply follow the etched instructions.

Here’s a closer look at how you can adjust the integrated variable ND + Circular Polarizing filter. Notice the two additional rings towards the front of the RevoRing. The front-most metal ring (where the markings are etched as seen in the above image) holds the variable ND + CPL and can be turned to adjust the filter’s intensity. A small metal handle is built into the second metal ring (also ridged) and allows you to adjust the orientation of the variable ND + CPL filter easily once it’s been attached to your lens.

Editor’s Note: H&Y reps have informed us that final production versions of the RevoRing will include some additional features:

• hard stop at the max point shown on the filter ring, restricting the movement of the VND filter beyond the maximum 10 stops (ND1000)
• additional guide pin fitted to the VND ring for better control
• new laser markings on the outer edge of the VND ring calculated and applied based on the maximum focal distance before any crossfade appears
  
  

BUILD QUALITY

The H&Y RevoRing Filter System feels very solid thanks to its metal construction. The RevoRing’s spring-loaded attachment system offers just enough resistance when turning that makes it easy to operate, but not so easy that you have to worry about it becoming accidentally detached. Overall, the RevoRings feel more than tough enough to withstand being tossed around within camera bags/cases or bumping up against other camera equipment. Just don’t go using one of the RevoRings in a game of ultimate frisbee.

All of the RevoRings worked as expected, although the spring-loaded attachment system could turn a bit more smoothly. When engaging the attachment mechanism on the pre-production units, you can hear the metal components rubbing up against one another. This didn’t cause any issues during our tests with the RevoRings, but can become a potential issue over time if not addressed. This could be easily remedied with the application of some lubricant on the final production models. In conversations with H&Y’s representatives, they’ve confirmed that although minor changes may be made to the RevoRing’s design, the pre-production samples that we reviewed are basically 90%+ of what the final production versions will be. Expect the final version of the RevoRings to be further refined when they ship out after the Kickstarter campaign concludes.

EASE OF USE

CONCLUSION

Likes

• Innovative attachment mechanism
• Allows you to use the same filters across different lenses of varying filter threads
• Well built
• Lightweight

Dislikes

• Doesn’t work with traditional square or rectangular filters
• No way to attach RevoRings onto ultra-wide-angle lenses that lack front filter threads

When it comes to filter holder systems, there are plenty of options available on the market that all basically work by using adapter rings. With the H&Y RevoRing Filter System, they’ve introduced a truly innovative attachment mechanism that does away with adapter rings altogether. The RevoRing’s spring-loaded attachment mechanism allows you to attach or detach filters in just seconds. This is significantly faster when compared to traditional filter systems where you need to first thread an adapter ring onto the front of your lens, then mount a filter holder to said adapter ring, and finally slotting in the appropriate filter(s).

Even though the units that we tested were pre-production samples, they all worked flawlessly. The spring-loaded attachment mechanism could be a bit smoother though, but applying some lubricant should alleviate this issue with the final production units. The only real drawbacks with the H&Y RevoRing Filter System are its incompatibilities with traditional square or rectangular filters and lenses sans front filter threads (common with ultra-wide-angle lenses that tend to have massive, bulbous front elements). As long as the lenses you’re using have a front filter thread measuring between 37mm to 49mm, 46mm to 62mm, 67mm to 82mm, or 82mm to 95mm, then the RevoRing could be a great addition to your kit.
