I went through that GBH sequence and rated them with 5 stars for perfect, 4 stars for just slightly off but still "Topazable", 3 star for somewhere between okay and totally out. I didn't make use of 2 star and just assigned 1 star for the failures. I could have broken the failures down into 1 and 2 stars but didn't.

Thanks to Alex for sharing that. I was hoping for the RAWs so I could see them in A7Info and see where the focus point was but not even sure A7Info supports A1 RAWs.
Regardless, performance looks good for that sequence. A few slight misses sprinkled throughout. I was actually impressed it came back into focus for the 2nd to last shot and almost for the last shot. Typically I just see it go out like that and stay out till bird leaves the frame.
Overall I'd say this is similar to what an A9II would pull off if shot in Zone (non-tracking) although possibly would have had some from beak focus more often than what we got here with the eye-detect. But pulling off what an A9II would do on a 50MP camera with the 200-600 is all I need. I really don't need focus to be better than the A9II (although I'll take it if it is). A9II already bests the R5 except for the added value of Bird Eye-AF for non-flight stuff. Now the A1 has that...win, win for me....hurry up March 4th.......Show more →
a7info does not support the a1, tried that on the DPR files

@arbitrage@ JUST KIDDING! He updated it on Feb 13 to add a1 support!
Having looked at Alex's images with A7info, it appears that the camera was mostly fooled by the sticks that the bird was carrying in its beak. Near the end of the sequence, where the bird moves to the corner of the frame, the AF moves to its body which suggests to me that maybe he was using Zone AF area. Not sure.
That's not necessarily bad. The bird was camouflaging itself , but it probably doesn't really show bird eye AF working in this case.
I set bird eye AF to a different color in a7info and I never once see it trigger in this sequnce. It is possible though that that info didn't carry to the jpgs from the raw.
Here the interesting part: A1 has the focus point indicator show just like how canon and nikon has. What I found is that even though you see on your evf the square of bird /eye af locked AND the result come out tack sharp on the eye BUT when viewing the focus point in A1 LCD itself, it show elsewhere.
This go back to the reason why I was never a fan of eye af because it is just an overlay. You can't just rely to it too much and expect miracles. All of this still and video just to show Sony delivers what they trying to sell. Is it 100% reliable? It would be naive to believe it.

Yeah I didn't see it on any of the images either. Also didn't see the Tracking indicator but then checked the EXIF and these were shot in Zone and not Zone:Tracking. Still I would expect to see the Eye-AF indicator although I've never tested that before.
I also found the AF points were way off the head in pretty much every image...many not even showing the points, only showing the centered target circle/cross.
Have others seen the Eye-AF indicator show up in A7Info for other images? Human, Animal or Bird?
I will have a look through some of the other available images from DPR and see if any show Eye-AF icons.

Like I mentioned in the Youtube comments, only final images will tell the tale here, not the green AF box in the EVF nor the final AF box in the image file, especially when talking about the 200-600.
I don’t have a Facebook account so I can’t see those files. Will have to wait for Geoff’s testing at this point before I’m convinced.
Below is the direct link (I copied it from Alex's FaceBook post) to the photos that Alex uploaded to Google Drive. You can open them up in Photoshop and look at the file info details.

Again, the EVF box display doesn't matter. The embedded AF box in the file doesn't matter. All that matters are the final images, the proof is ALWAYS in the pudding. From Geoff's ratings of your batch, roughly 40 keepers out of 60 sounds promising, given the tough conditions.
I set eye AF to red, other points to green. This is from DPR, one hit, one miss, both EyeAF.

Would be cool to get the sequence from the osprey or falcon as we have video confirmation from Alex that those 100% had eyeAF activated. But then again..... we're just doing this to kill time (14 days to be precise :-) )
the exif data indicates that eyeaf was not activated in the alex photo that i looked at, from his facebook link, perhaps something went wrong... it is activated in the dpr photo:

I'll go back and match the still from the video and upload again.

I noticed that as well when I looked but still upload since I know what mode I shot with. Let me go back to the folder where still and video of the seagull and see if the exif reading different
, but it probably doesn't really show bird eye AF working in this case.
