Sensei PRO 67-82mm Aluminum Step-Up Ring

Love these step-up rings. The pro version seems much easier to unscrew from lens than others I have owned. Many tend to gauld themselves to the lens threads, requiring a rubber glove or filter ring wrench to remove. These come right off easily.

I used to spend a lot of money buying multiple variations of the sample filter--UV, Gradient, Polarizer, etc. The challenge is, buying good quality filters adds up when you need a 52mm, a 67mm, and an 82mm version. This step-up ring is a nice solution. I now buy only 1 filter in the largest diameter I need (82mm), and use this adapter ring to secure it to narrower lenses. The ring is good quality, and I especially like the pro addition of the ridged edge, which makes it much easier to grip when adding/removing it. The only reason I didn't give 4 stars is the thinness of the material--there's a bit of flex in the ring. You have be extremely careful and patient when threading it onto your lenses to ensure you don't cross-thread or otherwise jam this adapter onto your lens. But for the money, this is a great solution to reduce the number of filters and save some dollars as well.
