Indeed, it's a classic reference for us macro freaks. I believe it's run by our very own kds315. I can only dream of having access to all those lenses to try out.
Panasonic GH1/G1, Canon FTb(n)/F-1, Mamiya C330F/RB67 Pro SD, Chamonix 45N-2, Nikon F5 + Assorted Lenses

Thanks for mentioning it and the kind words!
The real rarities are in the special lens section ... sssshh
