The Sony α7R IV has a 61.2MP CMOS full frame sensor that rivals medium format camera output in a more compact form factor, plus the camera’s 4 or 16 shot high-resolution pixel-shift modes can yield an amazing 240MP file size. Super-high res does not come at the cost of still of video image capabilities that include 10 fps burst rates and 4K video at full sensor width, plus incorporates Sony’s Real-Time AF Tracking system and dual slots for high-speed UHS-II cards.
