I haven't had a chance to properly use then yet. But they look like they'll do the job and are well made.

Ordered Thursday, delivered Friday, used Saturday on my new Fuji lens for use with close up filters. Well made, fitted perfectly, great purchase. This was my 2nd purchase from K & F. I was just as satisfied with my first.

They feel good on my lens and I have stuff from these before. Will be using them more often.

They all seem to be well made with no machining issues.
