Thank you for posting this link. I verified that my lens is not a part of this recall.

EyeAF was enabled at the time.

Thanks to the other person who referred me to the A7Info application. It reveals that for this image, the focus point was indeed on his left cheek/eye area.

Another person suggested that the player moved during the exposure... he's standing still and its unlikely that he moved even slightly. Besides, the strobes would have frozen him in place due to their brief duration. Next time I will try high speed sync to rule this out absolutely.

By the way, I have many images from this session with the same problem... it's not just one image I'm having the problem with.

Thanks to everyone who commented thus far... I really appreciate it.

That's helpful. I do note you shot in AF-S and in dark environment.

So a few things could be in play:

- It's AF-S. The kid moved between the time you locked focus and when you took the shot.

-Because it's an A7 camera in AF-S, the lens stopped down after locking focus, which can lead to focus breathing and missed focus.

-It's low light. In such low light, the AF system can struggle and be less accurate.

-An issue with the lens or camera AF system.

Tests I would do-- Test it in GOOD natural light, where you don't need those AD200s.

Test it wide open, at F4. If it is nailing focus in AF-S at F4 but constantly missing in a consistent fashion at F8, then it's focus breathing.

If it is focus breathing, use AF-C instead of AF-S. Then, it focuses with the aperture stopped down, which eliminates focus breathing.
