Not sure this is the proper location for this post but it seems to fit the open talk forum best.
first let me explain that I'm using a Sigma 60-600mm lens with the adapter to r5 body. I was out shooting last week and wanted to test the accuracy of focus tracking
and animal eye recognition. I was on a sandy beach with a few terns flying past me in a path parallel to the water's edge. I pointed the camera in the direction of the oncoming birds and hit the shutter as one came into view. I panned with the bird and never let up on the shutter release until the bird was a good distance down the beach.
the results were 23 sequential images of a Forster's Tern as it flew past me. I was using electronic shutter set to high and cRAW. The lens was set on 600mm and the camera was set to ISO1250, f11, 1/2000 sec. All 23 images were sharp and the only difference was the wing position and the bird position as it flew past me. Here are 5 of the images, the fist being the first of the sequence and the last is the last one in the sequence. the three in the middle are some of the better ones based on wing position and relation to the lens angle. the three in the middle are also cropped about 50% for better viewing and composition. The camera never lost focus on the bird and stayed on the eye as long as the eye was visible. This is one amazing piece of photographic machinery, 23 images in a single burst and all in perfect focus.
