Kase Revolution Ring Automatic Variable Magnetic Step-Up Ring

The Kase Revolution Ring answers a small but persistent annoyance in landscape and travel photography: the pile of step-up rings needed to run one filter set across lenses with different thread sizes. Rather than swapping a dedicated ring for each lens, this variable adapter automatically conforms to 67mm, 72mm and 77mm filter rings, stepping every one of them up to a shared 82mm diameter. It is aimed squarely at photographers who already standardize on 82mm filters and want to move them quickly between bodies without hunting for the right ring.

The mechanism is the interesting part. A four-point mounting system grips the lens filter ring, while a spring-loaded push button handles locking and release in a single motion, so the whole ring can be mounted or pulled with one hand. That matters when you are balancing a tripod, a filter, and changing light. At 74 grams the ring stays light on the front of a lens. It ships ready for 82mm screw-in filters, and owners of the Kase Armour system can add an 82mm magnetic adapter to fold it into a magnetic workflow. The tradeoff is scope: the convenience is real, but it is built around the 67mm-to-77mm range and the 82mm standard, so it rewards buyers already committed to that setup more than newcomers.
