Tony's funny. But hey, I have a list going of things I don't like about the A1 also. I actually have a full document I'm working on with the pros and cons between the A1 and the R5.
Most of Tony's points aren't things I use on the camera or care about (connectivity, GPS, pixel-shift).
Others are things I don't really agree with even though they are things I use: Flip screen (I hate the R5's flip screen and with Sunny Weather setting I have no issues with seeing it in sun), SD card speed (I've yet to be hampered by it and I shoot decent length bursts), card size (I'm running 128GB and never filled it in a day so 160 would be fine). The Human/Animal/Bird icon does change in the Fn menu but I guess not on the EVF/LCD...I wouldn't know as I turn off all overlays other than histogram on my screens (and of course I only shoot birds so it is moot point to me).
Overall AF better than the R5? No...flat out no....the only point I'll concede is that Bird-Eye AF in some tricky situations with messy background is better on the R5.
Better controls on the R5?...heck no....the R5 buttons are horrible compared to the A1, the A1 has better customization of the buttons.
Things I agree with in that video: the file quality limitation for 30FPS...I'm not really bothered by this as the Lossy files have never bothered me and it is all I've ever used on Sony but it would be nice to be able to shoot Lossless Compressed and not have to lose 30FPS.
One of the points just seem incorrect:
My shutter closes on power off and I'm in ES all the time so don't know what is up with his camera
