Ken I was at best buy yesterday and did the same thing. I also kept pushing the darn arrow thing with my thumb trying to move the focal point
I think you rally need to get it in your hands. It felt foreign to me thats for sure. But unlike Sony......I could get in that menu and figure things out
Ergos/grip is awesome
24-105 is amazing as I previously found out
I really cant comment on the AF or focal system. I kept tapping o the viewfinder to focus on something because i could not figure out how to move ot from back of the camera.......lack of familiarity for sure
I took a card with me but he would not let me put it in the camera
TBH I have had less of a problem picking a Sony up and using it than the Canon... I honestly have an issue with.. How do i term it, the lower end Canon interfaces? Like Im totally ok using a 5D IV, 7DII etc but give me a 6DII or 77D or something and its an immensely frustrating experience for my brain.. I can pick up a Nikon D600/750/850 and easily work everything on it easily without the amount of pausing, stopping and trying to find controls as on the low end Canon bodies...
The Menus i use less than the buttons on the back of my camera.. Yeah, Sony definitely has terrible menus but to me the terrible menus are simply not as big of a problem day to day as the buttons and lack of a joystick are for me
Obviously, YMMV on ergonomics obviously, as everyones hands/joints/physical capabilities are different, but id take the A7III over it any day still.
TBH I just think people whining over the IQ or whatever are silly, the EOS R, Z6 and A7III are all solid performers with IQ, and best IQ doesnt mean anything if your AF misses the mark, the interface is too clunky to work with while shooting, or any number of other ergonomic concerns that always irked me more..
