Sorry to hark back a few posts so I quoted the pic for relevance. I don't shoot birds I do shoot children (man that sounds bad)and I notice you say this is centre AF point in AI Servo- but there's nothing in the centre! Is this a crop and did you focus on the bird in the air? I'm curious as I often get poor framing as a result of using centre point AI Servo. Do you accept the framing to use the centre point then crop to achieve the desired result?


I figure BIF are similar to capture compared to children at martial arts. Always in motion and unpredictable. Thanks for any AF tips. For relevancy I'm using a 1D mkIIn.
