    77 to 95mm Step-up Ring (100mm O.D.) is rated 4.8 out of 5 by 4.
    Rated 5 out of 5 by from POOR LABELING - IT'S a 95 MM adapter (not 100) Maybe there's a reason some people care about the O.D. of an adapter ring, but I sure don't. When I received this ring it's labeled as a 100mm adapter so I almost sent it back. I thought B&H made a mistake. But after looking at the description closely it does say 95mm, but the packaging is misleading. It's a relatively smoothly threaded quality ring better than the cheaper ones. Considering the cost of lenses and filters I'd prefer to pay a little more for something that will last. This is difficult to cross thread and it's easy to tell if you accidentally start to. The ring is made of a heavy aluminum, not super thin like some others.

    Rated 5 out of 5 by from The 77mm to 95mm ring to Rule them All!! I recently purchased a few 77mm to 95mm step up rings from different manufacturers. This is clearly the best of the bunch. Very well made.

    Rated 4 out of 5 by from Good I use this to step up 77mm lenses to a 100mm step-down ring in a rail mounted Chrosziel matte box. Not 100% snug, but it does the job and keeps out all of the back light. It should also work with clamp on matte boxes too.

    Rated 5 out of 5 by from It is exactly what they said it would be. Feels heavy and solid, and Boris says that means it's good. No issues. Works exactly as it should.
