This vendor has better pictures, I have four look exactly like it, one with
AF confirmation chip. all my OM lenses (over 25) lock very well with it and
I have been using them for three years.

I don't think others can be any better, as all of them are made of brass. I
had an rather expensive one from Japan Kindai in 2003, used it on my 10D, it
was not any better either.

A really good one should be made with stainless steel (at least on the
spring) but I haven't found one yet.
