Wedding, Events & Documentary Photography — 24-70mm f/2.8 DG DN Art (2019): A professional f/2.8 standard zoom at two-thirds the price of the Sony GM — optically matches or beats the competition at every focal length.
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.
