The α7R IV from Sony marks another milestone in the evolution of the brand’s compact, full-frame mirrorless α7 lineup. The 61.0-megapixel Exmor R sensor combined with BIONZ X imaging engine delivers unprecedented resolution, fine gradation and low noise. Super-fast 10 FPS, ISO to 32k, 4k HDR video, & 5-axis steady shot make this the best α7 yet.
