The Sony α7 III (model ILCE-7M3) is a Full-frame mirrorless interchangeable-lens camera manufactured by Sony.[1][2][3] It was announced[4] on 26 February 2018 as the successor to the Sony α7 II and available April 10, 2018. Described by Sony as "the basic model," the camera shares many features with the high-end Sony α7R III and α9 models[5].


The camera features several advancements over the previous model, the α7 II, incorporating some features from the higher-end α7R III and α9.[6]

  • 24 MP full-frame BSI CMOS sensor
  • 693 Phase Detection AF Points with 93% coverage, inherited from α9 and 425 contrast AF points
  • Continuous eye autofocus mode called Eye AF with High Tracking ability
  • 5-axis optical in-body image stabilization with a 5.0 step shutter speed advantage
  • 10 fps continuous shooting (mechanical or silent)
  • Multiple 4K video modes: 4K/24p oversampled from 6K sensor output, or 4K/30p oversampled from 5K cropped portion of sensor
  • Larger 'Z'-series (NP-FZ100) battery from α9 and α7R III that is rated at 710 shots (CIPA measurement) - offering the world’s longest battery life of any mirrorless camera
  • Upgraded operability and functionality including addition of joystick for adjusting focus points, Dual SD Card Slots, SuperSpeed USB (USB 3.1 Gen 1) USB Type-C Terminal

The camera retains the 2.36 million dot OLED viewfinder from the α7 II, however with 0.78x magnification compared to the previous 0.71x magnification. The back screen loses the white dots from the previous model, dropping from 1.228 million dots to 0.922 million dots.
