The first version has L39, Y48, O56 and R60 filters and in the nameplate 1:2.8 f=8mm, and weighs 690 g and a length of 72mm
The most recent ones have L39, Y48, Y52, O56 & R60 filters, weight reduced to 640 g while the length was increased to 83mm.
A later version is known to have “MC” engraved on the nameplate
Table showing the different versions and upgrades in the coating of Olympus OM fisheyes. I’d take it with doubt since I can’t reach the source any more.

Can you help me?
This entry is incomplete. I’m looking for good pictures, both iconic on white background (front, top, side, angled) and “real life” ones. More important I’m looking for correct information supported by facts, proofs, articles. I’m also looking for manuals, flyers, catalogues etc. I can use as a reference or I can share it here. Credits will be given.
Images and credits
Many of the images I use here are found on the web, auction sites etc. I always try to track down the authors, ask permission and give them proper credits. Sometimes It is not possible, due to more than 22 years of research, so, if you recognize your pictures please contact me, I’ll be more than happy to give proper credits or take it down if you prefer.
