Battery Life
[Approx. number of shots]
The figures above are based on a fully-charged Battery Pack BP-511A, no Live View
shooting, and CIPA (Camera & Imaging Products Association) testing standards.

At 23°C / 73°F 800 640
At 0°C / 32°F 680 540
The actual number of shots may be fewer than indicated above
depending on the shooting conditions.
Pressing the shutter button halfway for long periods or operating only the
autofocus can also reduce the number of possible shots.
The number of possible shots will decrease with more frequent use of
the LCD monitor.
The number of possible shots with the BP-514 is the same as indicated
in the table.
The number of possible shots with the BP-511 or BP-512 will be about
75% of the figures in the table for 23°C / 73°F. At 0°C / 32°F, the figures
will be about the same as in the table.
The lens operation is powered by the camera’s battery. Using certain
lenses can reduce the number of possible shots.
Using the Image Stabilizer of the lens will decrease the number of
possible shots (shorter battery life).
For battery life with Live View shooting, see page 119.
