Ok. Gut reaction.
(And, I may not have any guts left after I send this and, they get hold of
me).
Dump the 2.0/35, 1.2/55, 1.4/50.
If they are only ok after stopping down two stops then, your 2.8/35-80
covers all of them already.
Keep the 2.0/90 if you need the extra stop and 10mm over the 35-80.
If you had Skylight or UV filters on any of them, retest without them.
Use the money the Zuki's would pay for them to get Vivitar Series 1's or,
whatever tests better to replace them. Series 1's are, I feel, a pretty
good bet.
Make sure you have a week's return privilege to test them.
Go through old Modern or Popular photography's for that era and, see what
tested the best.
Go to the library and check the "readers guide to periodical literature" to
help locate them.
I love the cameras (well, the OM-2's I have).
The 50mm 1.4 that came with it is the only Olympus lens I own.
I've never tested it but, it seems wonderful to me <deperate last minute
sucking-up>.
