High quality, but…

By Jacek R.

No doubt it’s a high quality item. Machining is made with high precision, nothing is wobbling and it’s reasonably tight. There is one “but” however… I bought it because I have upgraded from Canon 5D to Canon R6 Mk II with EF-EOS R adapter to be able to use my EF L-Series lenses and I noticed that the old OM-EF adapters I have don’t provide AF confirm with R6 plus EF-EOS R adapter. Now… Canon L-Series lenses work correctly with EOS R6 (AF and everything else works as it should), but even this OM-EF adapter is new, it’s AF confirm works only with Canon 5D but it doesn’t work with R6 and EF-EOS R adapter. Probably AF confirm chip in this adapter is of an old type and simply doesn’t work with newer Canon bodies

Does Exactly What It Is Advertised

Bought it to us my OM manual focus lenses on my 5D MKII. The focus confirmation chip works as advertised with the majority of my OM lenses. It doesn’t like the 35mm f2 very much, but does work part of the time. It works great with the other lenses.
