Very good quality adapter. The brass makes it very easy to screw on and off. The machining is great quality.

Brass def the best option for adaptor rings. Unfortunately they dont do a 82-95 mm for some reason . But high quality item used over and over this is my second one to get rid of a alloy version

Top quality product. Never jams when swapping out on lenses. Highly recommended way to use your larger filters with lenses that use a smaller thread. I have a few of these now, as it is much cheaper (and easier to carry around) that multiple 'same' filters.
Basically a metal ring with a big hole of air in the middle. Got it as a gift for my son. It will allow him to attach a newly gifted Variable ND filter on any of his lenses. His lenses have either 67 or 77mm threads, so one filter is all he needs to work with any of his lenses. A lot cheaper than buying two filters. It is nicely machined, and should last forever if the threads don't get buggered up.
Another quality NISI product. These are the best step up rings Ive ever used.
Solidly built. Happy with its overall quality. Would recommend.
Actually, the only step-up ring I found that was both brass (most are aluminum) and knurled (most are smooth). And the price was good.
Okay, it's just a step-up ring, but the quality is first class. It's all brass, so it won't bind (as aluminum rings can) on your brass-ringed filters (e.g. B W, Heliopan, etc).
I have a seldom-used polarizing filter that was supposed to go with a Mamiya telephoto on their short-lived 35mm SLR line. Camera gears wore out; lens has coating separation, but the filter is mint. This brass threaded step-up allows me to use the 72mm filter on a 62mm Nikon lens. Recommended.
