A7 IIIvs RX100 VI
GearScore™ Verdict — Which should you buy?
All-Round Photography & Video — A7 III (2018): Still one of the best all-round cameras money can buy — particularly strong used. The A7 III proved that full-frame doesn't have to mean compromises, and nothing at this price point has meaningfully beaten it.
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.

A7 III (2018)
- Enthusiast photographers upgrading from APS-C for the first time

RX100 VI (2018)
- Travel photographers who need versatile reach in a pocketable body
