Look at the bayonet on a 3, 3T(i), 4 or 4T(i), and at 9 o'clock on the
bayonet you will see a black plastic button which sits proud of the bayonet
face.  The 'bad' mounts have a screw which passes over this button as you
mount the lens - the button pops into the screw hole, and has its tip
sheared off as the lens is fully mounted.

Anticipating the next question, it's the reset switch for the spot metering
memory, which clears tht memory when you change lenses.

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).

Thanks.
