I just watched the Tony Northrup A1 video. I found it quite informative and reasonable in presentation. I've stated here in C.R. the biggest benefit of the A1 (via specs) to me has been the EVF with it's higher magnification
, so that it's a wider & taller view to the eye
which is sorely needed in all EVF's, plus the higher MP and 240FPS
makes it just as good (according to him) and better (with live info) as an OVF. Now I can't test that or make that claim, but it reinforces my view of how great that 1 item is, and I hope Canon comes out with a similar EVF in their upcoming top R... bodies. I noticed jayphotoworks (thanks!, above) mention that EVF 240 fps reduces the magnification to "standard" (smaller) size, so I can only hope that a future Canon version allows 240fps at max. EVF magnification.
Tony also mentions other good & bad things about the A1 and how the R5 often is better in many regards, especially animal/bird eye AF which is crucial to me. I thought it was a very good review, and while Tony is certainly not perfect and may be very self-serving (and enjoys a very good living from it) I don't hold that against him, and instead enjoy the good information, and often interesting history of past photo developments, he does provide.
