Tips and tricks for shooting with the 85L

It is a challenging lens. Have you guys discovered something that has changed/helped your keeper rate with it? Obviously focus/recompose at f/1.2 is a bad idea. What else do you guys have to add to this? I am happy with my keeper rate with it overall but I also realize that it isn't your average lens and there may be some things that I don't know about that may benefit me/you/us.

I found I could trust the 85L II to hit focus a lot more consistently at f/1.2 on a 1D Mark III or 1D Mark IV than I could on a 5D. The tightly clustered AF points are trouble with off center subjects, and at least on my 5D the outer points just were not accurate enough for very thin DOF.

General tips:
1) Release the shutter as soon as you can after achieving focus. Time allows you to sway.
2) Avoid focus / recompose
3) Think a little bit about the aperture you are using. If the DOF is so thin that you cannot tolerate a 5mm focus error, do you really have enough DOF for the subject and composition anyway? Perhaps it's time to stop down.

Very good tips from Jeffrey.

Using a 5D2 here. If I'm shooting at f/1.2 I'll usually AF with the Servo focus, or I'll simply MF using a precision focusing screen. Either way, at f/1.2 I usually take a few successive shots to ensure one that is properly focused.

Liveview + Z-finder + manual focus = 100% keeper rate.
