Verdictwhich should you buy?
S5 IIX — Professional Video, Filmmaking & Hybrid Shooters On L-Mount: The S5 II with ProRes RAW and 6K Open Gate — the most serious L-mount video tool in a portable, weather-sealed body.
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.
