My friend shots the Sony A9 (20 frames a second and when in silent mode you don't hear a thing, strange). Anyway, when he first got it he was shooting with the 100-400 now he has the new Sony 400 2.8. Yes, it is also very accurate and the results he gets are pleasing. But for me, I can match him with my current Nikon equipment, but I am slightly heavier than he is. However, when I get my Nikon 500 f5.6 I will actually be lighter with my D500 and 500 5.6 than his A9 with the Sony 400 2.8. Well, they will be comparable in weight. As far as focusing goes, both camera's deliver. I do like what my D850 does with the 200-500, details are just WOW.

My Olympus OM-D EM-1 Mk2 has this feature. I can choose eye focus on both eyes, left, right or off. It works well especially when the animal is in profile

Sony 400/2.8, now there's a chunk of $$, just wish I had that as pocket change....absolutely nothing average about the 850, seems to be the Professional Industry Standard/Choice now, I'm sure Canon users would say otherwise. When you get down to it, many/most of the time its the photographer and their knowledge of their equipment that coax out those awesome photos, no matter what camera they're using. Unfortunately I'm not one of them....just keep trying to improve and if technology helps, I'll use it....Cheers Bill

The Canon A2E was a waste in shooting sports. I hope your brand/model works great. But I found Canon would go nuts whhile tracking action. I wish you luck, no camera can track your eye while you are tracking action, it is impossible! i

I would agree with you that it may be difficult for the camera to track your eye while you are tracking action.
BUT. The newer Nikon camera's (D500, D850, D5) all have a separate focusing system that is very accurate. I use a focusing system Nikon calls GROUP AUTO FOCUS, Nikon gives you a cluster of 4 focusing spots in a diamond arrangement, you can put the four dots in that cluster almost anywhere in the viewfinder, since I shoot wildlife in motion, I put my four dots in the center of the viewfinder. Actually its about 16 points but they are all contained within the 4 dot spread.
Anyway, as long as one or more of the four red lite square dots are on the subject, the EYES will be in focus. In the shot below, the Green Heron was coming across my field of vision so fast I only had time to put the dots on it and shoot fast before he was gone. Results speak for themselves. By the way, I do not use rear button focus, I have that rear button assigned to single spot focusing, that way, when a bird flies into a tree or bush, I simply push my rear button and I can put that one focus dot right on the bird. Works every time.

Thanks Bill for that 'spot' focusing button tip. I'm going to incorporate it....
