Battery Life
The highly efficient components in every EOS camera keep power consumption to an absolute minimum, allowing you to shoot for longer on a single charge. The CMOS image sensor, for instance, requires significantly less power than CCD sensors. And
by integrating all key camera processes on a single chip, DIGIC technology works more efficiently than conventional image processors. The table below details approximate battery performance for current EOS models. Turning off the image preview function on your camera gives you significantly more shots per charge. -----------------------------------------------------------------------------
