GearScore™ Verdict — Which should you buy?
Landscape, Studio & Professional Stills On L-Mount — Lumix S1 (2019): Built like a tank with one of the finest viewfinders ever made — the S1 is the choice for photographers who prioritise build quality and IBIS over AF speed.
Content Creation & Vlogging — A6400 (2019): 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.
