I have come across that one in my searches, looks a nice lens and seems to be highly regarded in the MF/vintage lens community. I don't mind spending a bit more if I know it's going to be good, can save a little extra. Atm my 'gear fund' is just a little on the low side, once I clear a few other boring bills I can start looking to something juicier so will have a look into it. One annoyance though, id the price of adapters has rocketed here, people trying to sell them for €25+, same ones I used to get for €5-10 just over a year ago! I had a bunch of them, MD/FD/Nik etc, had a few old MF lenses at the time and enough adapters to just leave them perma stuck on. I think I might actually order a few from China, and while waiting on those I'll continue the search, that is part of the fun
A 2.8 is really nice, and if I was going to stretch to that the older Nikon 80-200 2.8 original mk1 is probably hard to beat if you can get a good deal. There's the less flexible Canon FD 200 2.8 [in this price range] but from what I've read/heard it's thrash wide open, needs stopping down to at least 5.6 which defeats the whole point of a 2.8
