Another comment that A1 bird eye AF is not dependable even on large stationary birds--Jordan/DPReview TV
I think Tony performed Bird Eye AF with the GM 600/4 and looks like Jordan is using the GM 135/1.8? Wondering if there is some optimal setting(s) needed for maximum Bird Eye AF performance or as Tony alluded some other issue with the A1's AF that he has communicated with Sony engineers.

Found Lok's hands-on. It's not in english, but how can you not like Lok? I feel like you get the jist of it.
he uploaded the english version now
while fashion shows are not happening now it's odd that only him showcased the combination of silent shooting with flash sync at 20fps, it should be a big deal for the industry
A cropped lens will still form an image on the entirety of the the full frame sensor. It will just be soft and vignetted outside of the APS-C portion of the sensor. (unless they add a field stop to the design, which they probably won't, since the sensor already accomplishes this)

Fro summary, a1 will be his primary body for now, and he beats up on the sony 70-200 F2.8 repeatedly. The human eye af looks really freaking good.
Thanks, glad to get the gist without having to watch Fro's actual video. The content on his videos is usually fine, I just get tired of all his emoting.

I can easily imagine that. Super cool! Something for Guy's runway show ( @GMPhotography ).
And according to him, the BE-AF is impressive in tracking falcon in flight and better than that of the other camera brand that starts with a C although he forgot how to spell the name correctly . His words, not mine...
Man, Bird AF reviews are all over the map....but I'm guessing it is because a lot of these people are trying to do it out of Wide AF mode when there are all sorts of other things in the frame.
Even though the guy in this clip below has an easier situation he is doing the technique perfectly, Zone AF, moved up so it just catches the top of the perch when the bird isn't present and when the bird lands it is centred in the Zone.
This looks as reactive as my R5 is when a bird lands on a clean isolated perch. You will need to click through to his Flickr to watch the short clip: video-1612494415 by Yik Lim, on Flickr

Repeating what Mark Galer said, my motto before AND after all those reviews remains the same "Shut up and take my money"!
The more I learn and think about this camera the more I'm realizing that for the type of photography I do, there is no reason I'd ever take out my A7RIV, A9II or even my R5 after having the A1. I'm going to hang onto the A9II and R5 just so I can compare directly to the A1 for a few weeks but unless there is some glaring fault with the A1 I think everything else will be sold.
What I'm going to do for a 2nd body remains to be seen...I'm thinking either A9 (original) or A7IV (depending on what it has in it). The 2nd body would just be for travelling so I'm in no rush to get that

Quite a positive evaluation!
That is interesting...maybe overall tracking is better than C but nothing I've seen so far with Bird Eye-AF specifically is any better than the R5. I'd probably give the R5 the slight edge going off of what we've seen so far from the A1 and my own use of the R5 for the past 3 months.

The best backup body is the exact same body as the main camera . Both can be setup to the exact same settings down to the minor setting. And I am not joking about it. You don't have to think what setting is where, it is just automatic. Especially now that the menu is different than all the previous Sony cameras, except for the A7s III but you are not considering that anyway. But I know it is going to be pricey . I will wait several months and I will look into that possibility.

I saw this earlier and thought it was impressive thermals compared to the R5 (with firmware update removing artificial timer). I realize that Sony put more effort into heat spreading for the A1 but this doesn't matter too much when the body is a closed system covered with "insulating" wrap. The body is a very poor heatsink relying on convection, poor surface area, and high thermal resistance on most of the frame. The A1 just seems to be generating less heat compared to the R5. My best guess is that they are taking advantage of the dual processors to distribute the load while clocking at a much lower frequency with lower voltage. Again, this is just my personal guess based on no facts at all.

this one is more extreme, he basically baked the camera while recording, the numbers are very positive
