See my Sony mirrorless wishlist at B&H Photo.
I recently reported on autofocus accuracy with the Sony A7R II and the Sony 85mm f/1.4 GM, using conventional spot-focus AF-S, which is normally the way I shoot just about everything when not using manual focus.
I also tested with the Eye AF feature and found similar results (not published as they were similar).
However, yesterday and today my ad-hoc testing with thefeature shows that it has serious potential for improving results any time the subject or photographer is moving, even a little.
Thefeature is well hidden by the Sony menu system and it apparently cannot be coupled to the shutter release (at least I have not found any way to do so)—it requires a separate button to invoke. Nor does it work with the Sony wireless remote control, a pity, since it would be a great way to do selfies. What a great way to render a good feature less useful! It’s almost as if Sony doesn’t want the feature to be used.
I’ve revamped my Sony A7R II setup pages as follows, this first page details recommended autofocus configuration, including how to configure to useas well as the button the GM lenses:

I just completed a series of head and shoulder portraits on our roof patio. Shade, f/2 1/2000 ISO 160.
I used the GM Focus Hold button with Eye Focus. I nailed eye focus on every photo (14). This function is fabulous. I could never have achieved this any other way. I am absolutely delighted with the lens.
The button makes the system really sing. Handling and feeling are great. Highest portrait hit rate ever.
