I have always wanted another 85mm F1.2L, I had a FD 85mm F1.2L back in the old days when I was shooting with Canon F1n bodies. Had to buy it, it was too good a deal not to. Will get around to calibrating it, and getting used to it. It is a huge block of glass, AF seems pretty reasonable if not particularly fast. Looking forward to having a play with it.
One of the things that is really impressive is the size of the rear element, there is no wiggle room at the lens mount, in fact the electronic contacts are actually hanging out over the glass.
