So you are saying, disable AF on the shutter button? And only use it on the AF or OK button?
Yes, that's what they are talking about. I actually have it the other way around - it focuses on shutter press *unless* I press OK to temporarily cancel it. I actually take quite a few pictures with my thumb on the OK button, and should really consider reversing this. Especially since I use MF so often; it's not like I'm *that* accustomed to having focus be "automatic".
Anyhow, basic principle is sound - if you're asking the camera to re-focus on every shot, you're asking for trouble. Focus for the first shot of sequence, then let it ride.
Quote: If so, when does AE happen?
That isn't affected. Meaning if you're in an auto exposure mode, it happens on shutter press or whenever you hit the AE-L button to lock it earlier. Or, in M mode, it happens on green button press (Ae-L for cameras without green button).
