Checking the number of recordable images/recording time
GB 80
• It requires a great deal of power to perform high quality movie recording or
continuous shooting using the APS-C size image sensor. Therefore, if you continue
to shoot, the temperature inside the camera will rise, especially that of the image
sensor. In such cases, the camera is turned off automatically, since higher
temperatures affect the quality of the images or burden the internal mechanism of the
camera.
• The duration of time available for movie recording is as follows when the camera
starts recording after the power of the camera has been turned off for a while. (The
following values indicate the continuous time from when the camera starts recording
until the camera stops recording.)
• The duration of time available for movie recording varies with the temperature 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 rises
and the recording time available is shorter than the values shown in the table above.
• If the camera stops recording due to the temperature, leave it for several minutes
with the power turned off. Start recording after the temperature inside the camera
drops fully.
• If you observe the following points, the recording time will be longer.
– Keep the camera out of direct sunlight.
– Turn the camera off when it is not being used.
– If possible, use a tripod and disable the SteadyShot function.
• The maximum size of a movie file is about 2 GB. When the file size is about 2 GB,
recording stops automatically when [File Format] is set to [MP4], and a new movie
file is created automatically when [File Format] is set to [AVCHD].
• Continuous shooting is possible for approximately 29 minutes (limited by product
specifications).
• For [1440×1080 12M] size movies, continuous shooting is possible for
approximately 20 minutes (limited by 2 GB file size).
