Hi,
I missed the reason as to why one version is good, and one bad. I see from
the 2 auctions cited that the mounts are different, at least with
regard to the
screw positions. But is it the screw positions themselves that is the problem,
or some other aspect of the mount. Would someone please explain why one is
problematic. (I gather that the difference only applies to OM-3 and
OM-4 bodies).
With these bodies the spot meter reset switch is built into the lens
flange and on some lenses the screws wipe over the switch, slicing the
top off it, if they happen to be in the wrong place.
Whilst Olympus always used three screws on the lens mount and the switch
was positioned to avoid these, many independent manufacturers used four
symmetrically placed - guaranteed to ruin the camera if fitted to a body
with such a reset switch.
Took me all of 3 minutes to achieve this on a brand new OM-4 back in
1984 - then I read the little pink warning sheet Olympus had placed
inside the instruction book. Honestly, how stupid would you have to be
to need to read an instruction book? :-(
Fortunately, Olympus repaired it under warranty, but in the process
damaged the top plate, which meant a further repair, taking three months
in total. I don't know if this was related, but that OM-4 was the least
reliable Olympus camera I ever owned and eventually I sold it after its
3rd warranty circuit replacement (of 7 repairs including those first
two). I just hope that my current one, having just been repaired
recently, hasn't started down the same track.
