[QUOTE="pforsell, post: 614868, member: 7240"] I agree this is the strong point of AF-ON button. The camera behavior will be modeless and the shooter can have continuous-AF, single-AF and manual focus all three at the same time. No need to change focusing mode or to move the focus point. This is best in using a DSLR, being able to exert complete haptic control over the camera without taking one's eye off the viewfinder. Trying BBF is addictive though, so i don't recommend it lightly. Once tried, forever hooked. :) [B]Disclaimer[/B]: don't read if autofocus doesn't interest you [I]Partly off topic, but there is some evidence in AF-C mode being a little bit more accurate in nailing focus than AF-S. The reason is that Nikon's phase detect autofocus is predictive and estimative. When we autofocus in AF-S mode the camera and lens estimate where the lens should focus and it goes there in one go. It is not 100 % accurate. In AF-C mode the camera and lens do continuous correction and refocusing and this re-iteration causes more accurate focus. I know from my own experience that this is true because I get more keepers with AF-C + BBF even with static subjects. Not by much, but noticeably anyway.
