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.
All-Round Photography — Z50 II (2024): Nikon's updated APS-C body with 4K/60p, improved subject tracking, and a vari-angle screen — a solid all-rounder.
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.
