The figures above are based on a fully-charged Battery Pack LP-E17 and CIPA

(Camera & Imaging Products Association) testing standards.
With a fully-charged Battery Pack LP-E17, continuous Live View shooting is

possible for approx. 2 hr. 25 min. at room temperature (23°C / 73°F).
Do not hold the camera in the same position for long periods of time.
Even if the camera does not feel too hot, prolonged contact with the same
body part may cause skin redness or blistering due to low-temperature
contact burns. Using a tripod is recommended for people with circulation
problems or very sensitive skin, or when using the camera in very hot places.
Do not point the camera toward an intense light source, such as the sun or
an intense artificial light source. Doing so may damage the image sensor or
the camera's internal components.
Set [z5: Live View shoot.] (the [z1]
