  • [Auto Power OFF Temp.] must be set to [High] to achieve continuous recording in most formats.
  • The duration of time available for movie recording varies with the temperature, file format/record setting for movies, Wi-Fi network environment, or condition of the camera before you start recording. If you frequently recompose or shoot images after the power is turned on, the temperature inside the camera will rise and the recording time available will be shorter.
  • High-quality movie recording and high-speed continuous shooting require large amounts of power. Therefore, if you continue to shoot, the temperature inside the camera will rise, especially that of the image sensor. In such cases, the camera will turn off automatically because the surface of the camera is heated to a high temperature or the high temperature affects the quality of the images or the internal mechanism of the camera.
  • Charts for estimated recording times according to ambient temperatures and [Auto Power OFF Temp.] settings can be found in the Sony a9 III Online Help Guide under "Appendix > Recordable movie times > Notes on continuous movie recording".
  • Using SDHC cards: The card will be formatted in FAT32. If the file size exceeds 4GB, recording will continue and a new file will be created automatically.
  • Using SDXC cards: The card will be formatted in exFAT. Even if the file size exceeds 4GB during recording, the movie will be saved as a single file.
  • Movies cannot be recorded simultaneously in both memory card slots when using a combination of the exFAT file system and FAT32 file system.
  • Video is recorded in a variable bitrate, which automatically adjusts image quality depending on the shooting scene. Therefore, recording times will vary depending on the content you are shooting and the shooting conditions.
  • Alternate Model Names: α9 III, a9 III, ILCE-9M3
