EOS R6 Mark IIvs Nikon Z8vs A6400
Which should you buy?
Portraits & Action — EOS R6 Mark II (2022): 40fps burst, 8-stop IBIS, and Canon's best-in-class Dual Pixel AF — exceptional for action, sports, and portrait work.
Sports, Wildlife & Hybrid Professionals — Nikon Z8 (2023): Z9 performance in a compact body — 45MP, 8K/60p RAW, and 20fps burst without the bulk or price of the flagship.
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.
