Finally, I never use the center point either. Why would I?
Just for amusement I thumbed through the first three pages of your Flickr stream to see what you shoot. I found it amusing that all but maybe 2 photos had the subject smack dab in the center.
This is just the stupid comment I was expecting from you. The faces are in focus right? They're faces aren't in the center. They are two AF points up the vertical set of AF points on my camera.
In other words, you're wrong. See ya.
