Verdictwhich should you buy?

X-T3 — Video, Street, Travel, Portrait: The camera that proved APS-C could punch above full-frame on video.

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.
