I actually like using wides close up to exaggerate size differences. I know the Olympus 24 2.8 and the 28 2.8 does not employ CRC/Floating Elements, but are they sharper than their Nikon counterparts?
The Nikon FA/FE/FM series are the perfect size for me, but I've never tried an Olympus. Plus the black OM bodies look so sleek.
Or am I just thinking about the grass being greener on the other side?
Bingo. Personally I'd stick with the Nikkors, and I have two Oly bodies, a 3 and a 4. I've never used them.
