Automatic
Number of images
that can be transferred
Approx. number of images
* Using a fully charged LP-E6. The number of images that can be transferred
is nearly the same at normal temperature (23°C / 73°F) and low temperature
(0°C / 32°F).
* When automatic transfer is performed during shooting of an image of
approx. 6.1 MB under conditions based on the CIPA (Camera & Imaging
Products Association) test standards.
* Fewer images can be transferred when transferring images over a wireless
LAN.
* Fewer images can be transferred when using bus-power external media or
GPS devices.
