Sony A7R III Brings 42MP Sensor And Blazing Fast 10FPS Shooting In A Full-Frame Mirrorless Camera
Sony also fits the camera with a new front-end LSI that is able to double the readout speed of the image sensors. The camera has an updated BIONZ X processing engine that is 1.8 times faster than the processing engine in the outgoing A7R II. All that fancy technology gives the camera an ISO range of 100-3200 that is expandable to ISO 50-102400 for still images. A 15-stop dynamic range at low sensitivity settings is featured.
Sony built in the ability to shoot full 42.4MP images at 10fps with continuous and accurate AF and AE tracking for up to 76 JPEG/RAW images or 28 uncompressed RAW images. When in live view mode the camera can shoot continuously at 8 fps, while 5-axis in-body optical image stabilization helps remove shake from images when shooting fast.
The AF system has 399 focal-plane phase-detection AF points covering about 68% of the image area in horizontal and vertical directions. A7R III users also get 425 contrast AF points, which is 400 points higher than the A7R II. Video recording at up to 4K resolution is possible across the full width of the full-frame image sensor is supported. Full HD video can be recorded at 120fps at up to 100 Mbps.
Images and video are stored to dual memory slots with one supporting UHS-II SD cards. The Tru-Finder (viewfinder in Sony terms) has 3,686k dots for extreme accuracy. The camera also gets a new software suite and can transfer files to a smartphone, tablet, FTP server, or PC via integrated WiFi.The Sony A7R III will ship in Europe in November for €3500, or about $4,135. It's not clear when we will see the little beast launch in the States.
