Off topic, but I'd be interested in what you dislike about R5 ergos. From my 20D, through 5D, 5DII, 5DsR and R6, I have grown into, and like, the R5 ergos. Not sure what I'd change.
Agree.
My roadmap of primary cameras (aside of backups and experiments) was 10D-20D-5D-5DII-6D and now finally R6; I always found great improvements going on, and now the R6 I feel it's basically perfect, with all that I can ask to control it super fast during a ceremony (three dials, so exposure triangle in full control without using buttons like typically the ISO button all the way until 6D, the joystick, and the MFn button configurable to toggle focus mode with a single press).
The only thing I would change on R6, or better, implement, it's not about ergo: I use the viewfinder with the bare minimum info in it, so just the bottom row info ("basic shooting info"), like in an optical viewfinder.
The only thing missing, that I would love to costantly see with a display icon, is the current WB; If I want to see it now I have to activate the "detailed shooting info", which will burden my display with useless info on both sides of the screen. I would love an even deeper customization of the display/VF, where I can choose down to the single icon displayed, instead of having all or none of them.
Oh, and in that context, I would like a better customization of display and VF toggle, in the sense that I would love the display to be always turned off as I only work via VF, so I don't see why the rear display should be turned on when I remove the camera from my eye. But if I set to just use the VF, then also the menu appears in the VF, and that's really uncofortable. So I would love an option to exclusively use the VF, but then automatic toggle to rear display when I press the menu button.
