GearScore™ Verdict — Which should you buy?
Documentary, Portrait & Reportage Photography — Q3 43 (2024): The Q3 with the most human lens — 43mm, 60MP, and Leica rendering at its most natural and versatile.
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.

Q3 43 (2024)
