GearScore™ Verdict — Which should you buy?
Vlogging, Content Creation & Travel Video — PowerShot G7X Mark III (2019): The finest vlogging compact available — pocket-sized 4K, a flip screen, mic input, and USB live streaming in one remarkably capable package.
Compact Travel & Content Creation — A7C (2020): The A7C proves full-frame doesn't have to be bulky. Excellent battery life, reliable Eye AF and a vari-angle screen in a pocketable body is a compelling combination for travel and content creators. The A7C II improved on it, but the original remains a strong value buy.
