I have owned an A1 for well over a year, and I know what it can and cannot do. It can be particularly painful to get A1 tracking on a subject partially obscured by a tree - that is something this new AF solves by recognising subjects, and there are plenty of examples of it working. So I think this looks like a major advance - now I’m waiting to get a new A1 with that feature! The A1’s AF is very good, but this looks better, and will probably work even better connected to a faster stacked sensor.
While I’m at it, I’ll take that new rear screen, focus stacking, timed bulb, and some other niceties thank you!

Hi Tony, thanks for your answer. As long as the subject behind the branches has eyes, the A1 locks on it without problem. If non tracking wide or zone af doesn't work, then I personally activate tracking af for this very situation, and by simply putting the focus square on the subject, the camera starts to track it, and I usually discovered that it suddenly recognizes the eyes even if the subject is not big in the frame.
A.I. AF may work fine, who knows, but until someone experienced on FM checks for it personally I will remain skeptical. I mean, sure it detects the object through AI learned algorithms, but if the subject starts to move very very quickly, like birds in flight, then you could face that the RV lacks enough AF computing power to track it adequately and at the same time performing the neccesary AF distance corrections. Oh, yes, I forgot that the RV only shoots at 10 fps, so in that case it really needs lesser AF calculations by second than an A1.
As an aside, In the begining,I've activated the A1's AF point confirmation to show at photograph's revision, but even on the A1, a green square on an eye or on a bird it doesn't necessarily mean that the photo is perfectly in focus. On the contrary, sometimes the result is slightly out of focus at 1:1 (ALmost There, ALT), but recoverable after some image trickery. So a green square it is not the equivalent of a properly focused result, nor a green A.I. subject rectangle in the evf is indicative of a properly focused subject until you shoot and check the photo.
