Here's one wide-open at f1.2 from my Rikenon 55/1.2 (re-labelled Cosina). Shot on 35mm Portra 400

I feel like this thread needs good old-fashioned bump

I have had it for about a week but still learning it's quirks.

Looks like this lens goes for comparable prices to the SMC 50mm f1.2. Anyone here have both and can tell me which is better??

I know this thread has been dead for a while but...

Does anyone know how to (or a link to how to) fix a loose focus ring on this lens? Mine doesn't focus anymore and I'm really bummed about it.

I bought a bunch of rubber tools (they look like rubber stoppers) that I was hoping would help loosen the front name plate but that's not budging. I'm stuck and hope someone has some advice.

Thanks.

looking for a judgement call here - the topic has come up before in this thread, but never really answered:

the title of the thread is 'Cosina 55mm f1:1.2 club'

are only Cosina-branded lenses allowed or are the Cosina-manufactured 55mm f1.2 lenses also part of the club?
