Even updated to latest firmware (lens and camera), Eye AF is still limited
1

Using the A7rii in AF-C with the 85mm GM 1.4, Sony/Zeiss 35mm 1.4, and Sony/Zeiss 55mm 1.8, with all firmare updated for both camera and lenses, I find Eye AF to be quite limited. When shooting even at 1.4 or 1.8, I observe the following:

- Eye AF does work in scenarios with: lots of light, a subject whose head is straight and who is looking directly at the camera with both eyes open. The most "vanilla" or conventional shooting conditions possible.

But only about 50% of my portraits are like that. Beyond that, Eye AF falls down for me in virtually every other situation.

I find it especially frustrating it's not possible to easily toggle between eyes to focus on. Bizarrely, the Eye-AF function likes to select an eye that has hair or some other thing partially covering it, and not the other eye that is completely visible.

I very much hope that Sony can refine this feature and make Eye-AF a lot more flexible and capable in finding the eye in a greater variety of shooting situations.

Is this the experience others are having with the Eye-AF feature? Are there any suggestions folks have, who find the feature to be more adept at working in a greater variety of shooting situations?

I don´t have the A9, but I would really like a solution to enable forcing eye-AF to select the eye you want in the A7RII too...

I also find that, if only a single eye is visible, then the Eye-AF rarely works.

It seems like the engineers created Eye-AF to require two eyes being almost exactly level and mostly facing the camera directly in order to work. This is very limiting for more dynamic and creative shoots.

Unless you are doing a headshot or similar with a shallow depth of field.. then why even bother with Eye AF when Face Detect will do?

Shooting at 1.4-2.0 it's nicer if the camera can focus directly on the eye, instead of having the nose sharp and the eyes blurry.

Yes, I do shoot manually sometimes, but that's a very slow process and sometimes when shooting with models, a more dynamic tempo yields more emotion and expressiveness.
