I know i know. However my recent acquisition of this fine lens and today's zoo trip told me one thing.
Outer points refused to focus even on anything animal related. Eyes... nope... legs... nope.
Nothing.
Center point obviously fine. Also had a very poor SERVO performance w/ center point and my cousins kid running toward the camera starting about about a 150 feet away.
Just figured I'd share. Just waiting for a good price on a 5D3 at this point.
