Q1. Why does a thermometer icon sometimes appear on the LCD screen of my camera during Live View/Movie Shooting?
A1. The [
] icon is a warning indicator that the internal temperature of the camera is high. Increases in the camera's internal temperature are generally caused by either or both of the following two factors:
1. Extended use of Live View and/or EOS Movie functions
2. Use in relatively high ambient temperatures
The combination of extended usage of the Live View and/or EOS Movie functions and high ambient temperatures will cause the [
] icon to be displayed sooner than either of those factors individually.
When the camera’s internal temperature increases, the [ ] icon is displayed inside a red frame.
The EOS 7D’s warning indicator is shown in the above image as an example.
The position of the icon may differ depending on the model you use.
Q2. Can I continue shooting after the high internal temperature warning indicator initially appears?
A2. Yes, you can continue shooting after the high internal temperature warning indicator appears. However, if you continue shooting in either Live View or EOS Movie mode after the [
] icon is initially displayed, and if the camera’s internal temperature increases to a certain point, the camera will automatically stop recording images. If this happens, you will not be able to shoot again until the camera’s internal temperature decreases. Turn off the power and let the camera rest for a while.
Q3. Is image quality degraded by shooting while the high internal temperature warning indicator is displayed?
A3. Continuing to shoot while the [
] icon is displayed will not have an effect on the image quality of movies, but the image quality of still images may be degraded. If shooting still images, we recommend that you stop shooting for a while.
Q4. Can my camera be damaged if I continue shooting while the high internal temperature warning indicator is displayed?
A4. No, the camera will not be damaged.
Q5. How can I maximize the length of time that I can shoot in Live View mode and/or EOS Movie mode before the high internal temperature warning indicator is displayed?
A5. Please turn off the power frequently when not shooting. Also, we recommend not leaving the camera in high-temperature environments.
