The Mark IV sees a bump in resolution up to 30.4MP from the Mark III’s 22.3MP. Sensitivity, when expanded, still spans ISO 50–102,400, but the top standard setting is now an unusual ISO 32,000—a third of a stop higher than the Mark III’s ISO 25,600. Burst shooting steps up to 7 frames per second from 6 fps and can shoot large, fine JPEGs until your CF card is full when using a UDMA mode 7 card. Video capture now tops out at 4K at 30 fps, 1920x1080 at 60 fps, or 1280x720 at 120 fps. Plus, you can now operate the camera from, or transfer images to, your smart device thanks to built-in Wi-Fi—finally.
