The H&Y Revoring is a filter adapter for circular filters that has just launched on Kickstarter with an anticipated delivery date on November 2020. However, we’ve had a sample to test for a few weeks.
What’s clever about the H&Y Revoring is that it has a variable size. That means that instead of having to rummage through a load of step-up rings to mount your filter on your lens, you screw your filter onto the Revoring and then adjust its size to fit your optic.
H&Y makes the Revoring in three sizes, 37-49mm, 46-62mm and 67-82mm. Consequently, if all your lenses have a filter mount of between any of those sets of values, you only need one Revoring. If, however, your lenses span more than one range, you’ll need additional Revorings and different sized filters.
The 37-49mm H&Y Revoring accepts 52mm filters while the 46-62mm Revoring takes 67mm filters and the 67-82mm Revoring accepts 82mm filters.
If, for example, your lens has a filter thread of 72mm, you need the 67-82mm H&Y Revoring and an 82mm filter.
