Verdictwhich should you buy?
OM-1 — Wildlife, Sport, Outdoor: OM System's statement camera — class-leading weather sealing and the best IBIS in the business.
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.
