Originally posted by jimH That shouldn't have happened. If the lens is made to fit, it should fit, not just about fit. I don't have an answer for you, but I do think that I would find the offending part of the lens and see if it is protruding un-necessarily into the camera. If possible try to remove any projections that caused the problem. I don't think it is right.
I would disagree with "that shouldn't have happened"
One thing to remember is that the any camera that uses the KAF2 mount and this also includes the PZ film bodies, is that the power contacts are located in a place where previously, on K mount bodies nothing existed.
The lens in question was produced about 10 -15 years in advance of the KAF2 mount and therefore the third party manufacturer is not to blame for being unable to see into the future.
One thing that needs to be clearly cautioned with respect to mounting ANY old / legacy lens, or adaptor is to inspect it first, and very carefully look for any differences, before mounting it. There are several pitfalls, like the ricoh pin and this flange, that make interchangeable mounts non interchangeable.
maybe what we need, is a single sticky, at the top of each forum titled
"Is it safe to....."
This should include all known warnings about lens mounts, flashes, lens adaptors etc...
