• It requires a lot 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.) If you disable the SteadyShot function during
movie recording, the recording time is longer.
• 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 indicated 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. (When the camera is left for 5 to 10 minutes at a room temperature of
30°C (86°F), recording will be possible for about 3 to 4 minutes.)
• If you observe the following points, the recording time is 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,
the recording stops automatically when the file format is MP4, and a new movie file
is created automatically when the file format is AVCHD.
• The maximum continuous recording time is 29 minutes.
