Qvs A6400
GearScore™ Verdict — Which should you buy?
Street, Travel & Fine Art Photography — Q (2015): The camera that redefined luxury compact photography — a full-frame sensor, the finest 28mm compact lens available, and a shooting feel that is uniquely Leica.
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.
