Verdictwhich should you buy?
D850 — Landscape, Wildlife & Professional Studio Photography: The finest DSLR ever made — 45MP, 9fps, and nearly 2000 shots per charge in a body that still outperforms most mirrorless cameras for battery life.
A6400 — Content Creation & Vlogging: 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.
