Reaching the peak of resolution: 61.0MP full-frame CMOS sensor: Sony’s newly developed 35mm full-frame back-illuminated CMOS sensor with 61.0 megapixels enables the full-frame mirrorless α7R IV to attain expressive prowess once expected only in conventional medium-format cameras.Enhanced image processing engine makes the most of CMOS sensor: To match the excellence of the new image sensor, high-speed BIONZ X image processing engine is also further enhanced to faithfully reproduce details and reduce noise significantly.Features maximising superb 61.0MP resolution: The α7R IV’s extremely high image 61.0-megapixel resolution performance is maximised by other α7R IV advantages, one of which is 5-axis optical in-body image stabilisation with optimised algorithms to achieve up to a 5.5-stop shutter speed advantage.
