Bipin, besides the excellent (and both relevant to me) reasons that Larry and Bill point out, if you have your aperture very wide open, say above f/4, if you focus/hold/recompose, you are now out-of-focus as your DoF is quite shallow. *Especially* at f/1.4 where a tiny bit of movement by either photographer or model will throw you OOF.
Yes, the center AF point is the most accurate, but since you are focusing on eyes for portraits, and you likely have the camera in portrait orientation, the two straightline AF points that lie beyond the 9-grid are your probable choices. Then when you switch from portrait to landscape you need to quickly shift the AF point too. BTW, why do you suppose the AF points are switchable, anyway? :-) On Wed, Apr 17, 2013 at 2:36 AM, Bipin Gupta <[email protected]> wrote: > Hey, why are you guys switching focus points when framing your > subject.
