Sony all the way. I have the a7rv and use my old a7riv as a second body, the rv is light years ahead of the 7riv and I just keep finding this is the case with every new iteration with Sony systems. I’d bought a Canon r5 last year as I’d previously shot with canon for years and I’m just not impressed. Don’t like the color capability, can’t even color correct to where I’d like things to be whereas with the Sony a7rv color is neatly accurate straight from camera.
