GearScore™ Verdict — Which should you buy?
Portraits, Weddings & Creative Low-Light Work — RF 50mm f/1.2L USM (2018): The lens that proved the RF mount's potential — f/1.2 sharpness and bokeh in an L-series build.
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.

- Vloggers and content creators who need a flip screen and reliable AF
