This is a great lens. I did a lot of research before spending the money on this lens, and I was expecting a lot from it. It actually exceeded all of my expectations. I don't have the money for the 85L, and honestly I didn't want it because of the slower focusing.
My only minor complaints about it have been voiced before. It is a bit long on my 20D, but I knew that going in. Also there is just the slightest hint of CA, but this is only noticeable when viewed at 100%+ and in very high contrast areas.
I do not intend to sell this lens, ever. Cars--yes, house--
yes, but not this lens.
