GearScore™ Verdict — Which should you buy?
Everyday, Travel & Events On Fujifilm Or Sony Aps-C — 18-50mm f/2.8 DC DN Contemporary (2021): The lightest f/2.8 standard zoom ever made — 290g is astonishing for a lens of this capability, and it optically over-delivers at the price.
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
