I am curious how others are using eye controlled auto focus (EC AF) or if most people just don't bother with it at all.
I use back button autofocus, and I find it annoying that it may initially focus on where the eye controller is placed, but then it will jump to wherever I last placed a focus point using the smart controller.
Maybe I am wrong to use the Smart Controller to activate AF?
I'm also conflicted by how close my eye needs to be. I have a tendency to try to get really close to the view finder to prevent stray light from interfering, but maybe this is the wrong approach.
I have two different profiles set up, with or without glasses, and I always calibrate before shooting. At least I try, it always seems to fail when I'm out in bright light.
So far, it seems that EC AF is least reliable exactly where I had the highest hopes for it, which is fast paced action in sports, or out tracking birds in flight.
Where do you use EC AF? Are you happy with your success rate? Does it not like blue eyes? I just don't get it. Unfortunately it was a major selling point for me and I'm just not that stoked on it at the moment.
I have confirmed that I have whole area tracking Servo AF turned on.
