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.
High-Resolution Creative & Documentary Shooters — Sigma fp L (2021): 61MP and phase-detect AF in the world's smallest full-frame body — the fp L is the most capable iteration of Sigma's extraordinary compact.
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
