OK, now I am confused. I have a Pentax Spotmatic, and all my
Pentax screw-mount lenses are "SMC-Takumar". They also have the
little "auto/manual" switch on the side of the lens (the Pentax
Spotmatic focuses with the lens wide open, but must close down
to meter). Are you saying these will not work on the FTL? I
also have Tokina and other lenses for the Spotmatic.
So if the SMC-Takumar lenses would not work, then why would "other
screw mount lenses" work? I am curious what is different between
the Pentax lenses and "other screw mount" lenses, since they
both work just fine on my Spotmatic; and they also look the same
to my untrained eyes.
Maybe Pentax made some changes to their screw-mount lenses later
on, but when I bought my camera/lenses (in the mid '60s), they
all had that little "auto/manual" switch. I haven't looked at
any Pentax lenses since then. There is no "lens lock" mechanism
on the lenses of course (both Pentax and non-Pentax), and the
alignment is purely based on the threading, when the lens is
mounted until it is snug, then everything is properly aligned.
So why did Olympus thought it necessary to add a lock?
