The Sony A7R IV is the successor to the full-frame 42.4MP A7R III and features a newly-developed 61.2MP BSI-CMOS sensor with a native 100-32,000 ISO range (expandable to 50-102,400). Besides the higher pixel count, the A7R IV has an updated hybrid AF system comprising 567 on-sensor phase-detection AF points as well as 425 contrast-detect points, covering 74% of the image frame. It also has human and animal real-time eye (detection) AF, and features continuous shooting at up 10 fps, with full AF/AE tracking for bursts up to 7 seconds.

Although the body shape is familiar, Sony has done some upgrading to the weather-sealing, plus the body itself now features a fuller grip and a larger, reshaped joystick and a larger top-plate control dial and buttons. Inside, it has a high-res 5.76 million-dot OLED viewfinder, dual SD cards with UHS-II support, the latest 802.11ac Wi-Fi, and wireless PC connectivity for tethered control.

Video capture options include 4K recording up to 30 fps from the sensor’s full width, and Full HD at up to 120 fps, both with real-time Eye AF. There’s also a 6K Super 35 (more like APS-C) cropped mode downsampled to 4K.
