This Cavision 52-82mm Step-Up Ring enables the use of 82mm threaded filters on lenses with 52mm filter threads. The 9mm depth of this ring provides more surface area than a standard step-up ring. This provides a more secure grip to the clamp of your Cavision Clamp-On Matte Box. The step-up ring has an 85mm outside diameter for use with clip-on matte boxes. It features a lightweight aluminum alloy construction with a black anodized finish.

The ultimate step up
I wish I found this design sooner! Holds the filters closer to the lens than many low profile designs while being actually robust and providing the advertised additional real-estate for attaching/gaffing stuff.
Best step up ring design.
Seriously awesome step up ring. I only use 82mm filters, and even have 82mm to 4x4 adapters for each one, so I can either mount them on my lenses (That all have 82mm step up rings), or inside my mattebox. The 82mm circular filters are cheaper, cover almost as much space as 4x4 filters, are more durable because of their metal frame, and can mount directly to many lenses. The problem with many step up rings is that if they are wide enough to attach a mattebox, they increase the distance between the filter and the lens, which increases the risk of reflections between the filter and the front element. These solve this by being an offset step up ring. It extends out about as much as a normal thin step up ring, but also extends backwards to give you enough of a contact surface for a mattebox. Also it keeps the lens slightly more compact. This is the best design I've seen yet. It even has a threaded outside to help the mattbox grip the ring. Really smart product, and very solid.
