A6400vs RX100 VI
GearScore™ Verdict — Which should you buy?
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.
Travel & Vlogging — RX100 VI (2018): The RX100 VI trades fast apertures for a remarkable 24-200mm zoom range — giving it more versatility than any previous model. 4K/30p, 24fps burst, a pop-up EVF, and an articulating screen round out an exceptional compact package. Variable aperture limits low-light performance at the long end, but for travel and events where reach matters, there is no practical alternative at this size.
Who should buy what
A6400 (2019)
- Vloggers and content creators who need a flip screen and reliable AF

RX100 VI (2018)
- Travel photographers who need versatile reach in a pocketable body
- Vloggers and content creators who need 4K and an articulating screen
