The A7SIII is a primary video camera above stills.So Sony goes back in time with 12mp all is good. Canon uses 24mp not good. Got it. You certainly seem objective.
Sony has the A9 series as their standard resolution sports body and the A1 as their flagship. Canon are releasing a non flagship body after Sony already have and just before Nikon release theirs.
Some will be happy to be getting the R3 but going from some of the comments there’s definitely some disappointment as well.
