AGZ my set up is exactly the same static stuff ok ISH but birds in flight absolutely rubbish!!! I'm so disappointed with Sony for how this has happened to the flagship camera and the 200-600. I was out the other day photographing owls which flew 20 feet away and only got 2 max useable images all the rest where rubbish. The eye autofocus doesn't work and tracking is a waste of time now absolutely gutting.
