Gregg, I think you meant you focused on the top right eye....


From the composition, the image doesn't look like it would have suffered with a single, center AF point if you did happen to use it, then recompose. Not much of a change in distance or x, y axial movement, IMO.

Thanks for that Alan....you are absolutely left...I mean right!!

Actually Alan...even at only 120mm and the range being about 4ft or so, had I done center point and recomposed I might have missed. I took a shot where I focused on the nose, and the eyes were blurry!! Such a minute DOF!! But like I said earlier, I find I use the top left or right focus points the most in landscape orientation, and for vertical, typically portraits, I use the top, or top left or right. That way I don't have to recompose. More often than not, my subjects aren't standing still, so recomposing is really out of the question.
