Verdictwhich should you buy?

A7CR — Travel, Landscape & Portrait Photography With Minimal Kit: The world's smallest 61MP full-frame camera — A7R V quality in a pocketable A7C body.

A7S III — Professional Video & Low-Light Filmmaking: If video is your primary discipline, the A7S III is the camera. 4K/120p at 10-bit in a weather-sealed body with a 9.44M dot EVF is an extraordinary package. The 12MP sensor isn't limiting for video — and it's usable at ISO 409,600 in a pinch.
