EOS R10vs Nikon Z9vs A6400
Which should you buy?
Beginners & Vlogging — EOS R10 (2022): Canon's most affordable RF body — Dual Pixel AF and a vari-angle screen in a compact, lightweight package.
Professional Sports & Wildlife — Nikon Z9 (2021): The Z9 redefined what professional mirrorless could be — no mechanical shutter, 45MP stacked BSI, and 8K RAW in the most rugged Z body.
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.
