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] It was succeeded by the Sony α7 IV, announced on October 21, 2021.

Improvements over the Sony α7 II

[edit]

The Sony α7 III improved in a number of aspects compared to its predecessor, the α7 II, which was released four years earlier in November, 2014.

  • 4K video modes and 120fps full HD video instead of the A7 II's limited full HD (1920x1080) movie modes.
  • Continuous burst increased to 10fps instead of 5fps.
  • Maximum ISO sensitivity of 51,200 instead of 25,600.
  • Upgraded sensor with 693 Phase Detection auto-focus points vs. 117 Phase Detection AF points.
  • Newer Z battery system (NP-FZ100) rated to 710 shots instead of 340.
  • Battery capacity 7.2V / 16.4Wh (2280mAh).
  • Dual SD card slots instead of a single card slot.
  • Bluetooth for increased phone communication options.
  • Introduction of a touch screen but lower resolution 922,000 dot display instead of 1.23 million.
  • Newer ergonomic layout similar to the earlier A9 and A7R III including the addition of a joystick.

The camera's rounded feature set and launch price were highly praised. Reviewers noted it as a flexible and competitive tool for all types of photography.[6][7][8][9][10]

Issues

[edit]

The Sony A7 III does not have a vertical AA filter, it only has a horizontal one. It improves sharpness, but also creates a visible amount of moiré on clothes and hair.[11]
