Which should you buy?
Hybrid Shooters & Professionals — Canon EOS R5 Mark II (2024): The most complete hybrid camera Canon has ever made — 45MP stacked BSI, 30fps burst, 8K/60p RAW, and Canon's legendary Dual Pixel AF in one body.
Beginners & Family — EOS R50 (2023): Canon's most beginner-friendly RF body — Dual Pixel AF and beautiful colour science in an approachable package.
Professional Video & Low-Light Filmmaking — A7S III (2020): 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.
