I see the same behavior in my A7III. Face detection ON, and there is a lot of variability from shot to shot at close distances in AF-C. With face detection off (and flexible spot), there's less variability.

In low light, as the eyes are dark, the camera struggles to get focus, and some times it's hard for flexible spot to focus depending on the exposure. When face detect is ON, the camera seems to focus in other "easier" areas, so the eye is out of focus but for the camera the focus is easier and faster.

I think that's what's going on. And with face detect ON, as the camera "sees" other parts of the face being closer to the camera, the AF algos are all the time moving the focus point towards the camera, in case the person is moving, to correctly track. If you disable the face detection, the camera seems to just focus in the point, not moving it that far from it...

Do you have a before and after update video to share? With only one person aside from the OP thinking eye AF is broken with FW update 3.01, I tend to be highly skeptical.

i posted exactly the same thing many post earlier.

i am thinking of turning of face detect and just use the plain flexible spot for afc.

That is exactly my use case most of the time. Afc with flexible spot m. With this new update, I find my hit rate dropped .... not sure if turning off face detect helps...
