GearScore™ Verdict — Which should you buy?
Professional Video, Documentary & Cinematic Filmmaking — FX3 (2021): The definitive run-and-gun cinema camera — A7S III sensor quality in a body built specifically for video professionals.
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.
