I'm not quite convinced about the colour/contrast/saturation thing. If you do any kind of PP to your images whether RAW or jpeg, you adjust those parameters. I've not really heard of anyone saying they don't PP their 85L shots because the lens renders everything 100% perfect. If shooting with the 1.8 means pushing to saturation slider to 10 instead of 5 with the L, then really, what difference does it make? It's no less work.
And the AF is brutally slow. I'm not talking about full sweeps through the range, I'm talking about catching moving people. The 1.8 is one of my favourite wedding dance floor lenses. Erratically moving people in the dark. One of the reasons I got rid of the 1.2 because it got me something like a 5% keeper rate in that situation, which is pathetic. By the time the 1.2/s lens elements move into position, the person has already moved too much. The 1.8 snaps into focus fast enough to catch them before they've moved too much to mess the shot up.
Well I was not satisfied with the color/saturation/contrast part of the 85 1.8 (whatever I did in PS did not help) and that's why I made the move to go to 85 1.2 and I am a happy man. I don't need the AF speed as well for the stuff I do with 85L.
