Verdictwhich should you buy?

OM-5 — Outdoor & Adventure: The toughest camera at this price — IP53 weather sealing and 7.5-stop IBIS built for adventure photographers.

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.
