The RX100 VI is 34 mm narrower, 39 mm shorter, 40 mm slimmer and 442 g lighter than the A1 II.
Drawn to scale from the makers' dimensions (W × H × D). Front shown, depth on the slanted edge.
A1 II — Professional Sports, Wildlife & High-Resolution Studio Work: The most complete camera ever made — 50MP, 30fps, 8K, and the world's best EVF in a single flagship body.
RX100 VI — Travel & Vlogging: 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.
