Jeez, Nikon? You should have bought yourself a good Olympus OM setup.
So much smaller, lighter, better glass, much nicer macro system, better
metering, and so forth.

which would have turned out to be a dead end.

at least old nikon lenses can still be used (with rare exception).

the only good thing olympus had was the om-3 and om-4, with the
multi-spot metering. otherwise, it was nothing special that the others
didn't have.

Old OM glass can be used on any EOS camera among many others.

a lot of lenses can be used on other systems with adapters. big deal.

the problem is that it brings significant compromises, including having
to set the aperture manually since the camera can't do it and also
stop-down metering, along with being manual focus lenses.

Their
telephotos were faster or longer than the competition, and they had (as
I said) an excellent macro system. Also the meters would work in much
less light than any Canon or Nikon camera, which might not be that
important to many users but if you pushed 3200P to 12800 like I often
used it, it was pretty handy to have.

not significantly, if at all.

Plus Olympus managed to put the shutter speed ring in the right place.

nope. putting it on the lens barrel was one of their biggest mistakes.
i know some people liked it but most did not. if it really was 'the
right place', other companies would have done it too.

the 'right place' is a thumbwheel on the back (and an aperture
thumbwheel in front), however, that was not possible with old
mechanical cameras.
