It was rather warm today, in the 60's, so I broke out the 300 2.8 and did some tests with my kids in the back yard. A few bursts with my daughter running full speed towards me. Ai Servo, single point (center), focused on the 'dog' on her shirt. I know this isn't one of the 90's day where the issues are suppose to more prominent, but hey I'm just having a little fun anyway!
Looks good to me!
