Hybrid Video & Photography — Lumix S5 II (2023): Phase-detect AF changed everything for Lumix — the S5 II delivers exceptional hybrid performance with 6K video and genuine full-frame value.
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.
