Which should you buy?
Sports & Photojournalism Professionals — Canon EOS R3 (2021): The pinnacle of Canon's mirrorless lineup for speed — Eye Control AF and 30fps burst in the most rugged body Canon has ever produced.
Wildlife, Sports & Hybrid Mft Shooters — Lumix G9 II (2023): Phase-detect AF transforms the G9 II into a genuine MFT all-rounder — the best Lumix MFT camera for both stills and video.
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.
