the 86 mm side is so short it is useless for holding in a series 9 filter. why don't they make it better and charge more for it? it is a total waste of money.
Pros: Properly sized and machined. Nice anodized coating. Cons: not unique to this step-up ring at all -- no knurling (could not find what I really wanted: knurled and made of solid brass) -- so it is possible to get it "stuck" to the camera lens front or the back of the filter you are using it to mount to that lens. So, take care not to over-tighten, but tighten enough that the (presumably expensive! since it would be 86mm) filter on the front doesn't fall off.
