GearScore™ Verdict — Which should you buy?
Professional Sports, Wildlife & Press Photography — EOS-1D X Mark III (2020): Canon's DSLR masterpiece — 20fps live view, 5.5K RAW, 191 cross-type AF points, and dual CFexpress. Almost certainly the finest optical viewfinder camera ever made.
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.
