Olympus gear seems to keep some price level, probably for rareness compared with other quality gear. A Zuiko 85/2 I watched last weekend went for 252 USD (double what I've paid for a Nikkor-S 85/1.8) and OM-4 seem to go for 200 EUR even with no function guaranteed. So I think building up some basis will cost some time!
