Originally posted by Lowell Goudge with any lens, and stationary objects, some times I have seen AF-C snap in on focus then re-adjust out of focus. I suspect that AF C is much more appropriate for moving subjects and AF-S is for stationary. The issue is that in AF-S moce the shutter is interlocked with focus confirmation, so mopst people use AF-C so the shutter can trigger without AF confirmation.
I wish there was an override for this,
I don't use AF-C, but I have my OK button set to to cancel AF (other cameras have a AF button that can be used in this way). I use this to temporarily disassociate AF from shutter half-press, but I wonder if this wouldn't perhaps also work in AF-C mode to do what you are suggesting?
