I purchased this recently and found a message on the box saying it was not compatible with Leica lenses with an infinity lock. Is there an adapter that is compatible?
I did the same thing and researched the same question. Unfortunately, they only make a Type 1 for a 50MM with an infinity lock. I was little upset that there was nothing said prior to the purchase. I showed the ring to a machinist and he seems to think it won't be a problem cut out a portion of the flange to allow the lock to work. I'm going to give it to him after the holidays.
