Cory,
Thank you. Can you remember if anything else came adrift when you removed
the flange, or was it very straightforward? From bitter experience, I know
that I'm much better at taking things apart than I am at putting them back
together.
Unfortunately, it depends on the lens from my experience. I was
successful on a Vivitar 28-105/3.5-4.5, but unsucessful on a VS1
70-210/2.8-4.0 (gen3). The former was trivial... four (six?) screws and
the whole rear flange came off in one pice to be adulterated. I could
never figure out how to get the rear flange off the latter. The -A
mechanism was much more cantankerous on that one. After messing with it
for awhile, I realized that if the aperture ring was in the 'A' setting on
that lens, the *Richoh* pin retracted. If it were to ever fall in the AF
hole, putting the lens on 'A' would disengage it. Of course, the lens is
almost always on 'A' anyway.
Sorry I can't be of more help... I'm sure it depends on the lens.
-Cory
