Thanks Jannik, I'll have a look. Glad the OM 100/2 impressed, it's my next favourite, though taking the weights into account, probably my favourite ;o) Pity about the adapter issue though, was that for the OM or the MP?
I am still interested in finding an OM 90/2 to compare it with. So far I've seen results from it, which impress, but no direct comparison with the 100/2.
I do wonder how much different copies perform. I had my OM 100/2 "set up" by an "Olympus-Approved" repairer, but still not sure how well they did it, as near minimum focus it isn't very impressive. I have since come across Gordon Friedrich of OM-Labor in Frankfurt, he's just serviced my OM 50/2 and made a big improvement in its performance. Good to deal with too, and worth the extra postage to get it to someone who knows what they're doing.
I now also own a TS-E 90/2.8, but the EF-FE adapter hasn't arrived yet, so haven't been able to try it out. All I can tell at the moment is that it is fairly compact,(for a TS), but also a bit heavier than I like. I expected it to be a bit "worn" for the price I paid, but it's in pristine condition, and looking on eBay history, I see the seller reduced it by £200 for a quick sale!
