Originally posted by SOldBear When you push the lens release button on the TC and try to turn the lens, does the lens turn at all?
Yes, part way, until the aperture ring reaches minimum. This is why I think I have the TC's aperture coupling on the wrong side.
Originally posted by topace Having used the bokina, I cannot think of a TC I wouldn't disassemble or break in order to keep it from damage.
Believe me, I agree, and would happily destroy the TC myself if I knew how to do so without damaging the lens.
(topace is correct; the Ricoh pin issue is when mounting a KR lens on an AF mount. I only brought it up to make it clear that this is
not a Ricoh pin issue.)
