Re: WOW. 1.4x and still focus the 70-300

I was using AI Servo the majority of the day and my focus rate was great, 95%+. Didn't notice any major degradation between the 70-300 with TC and without, But then it was very sunny, open and Elephants are big and relatively slow.

The day before I was trying to shoot a Crane as it flew away, and got 30-40% focus with the 70-300, was not using the TC that day.
