I've been trying to build up an OM system after having some pretty good success shooting a few events with an OM4.

However, I was browsing some of the lenses on Ebay (40mm F2, 24mm F2.8, etc.) and could not believe the asking prices. Perhaps it has to do with less supply than say Nikon or Canon lenses but .... wow. I'm just stunned.

Has the Olympus OM system really made a massive resurgence such that lenses that people couldn't get rid of before are now becoming crazy popular? Is it the mirrorless digital systems?

Or maybe I'm looking at the wrong sellers
