Power-Saving Circuit
The main parts were designed so as to
require the minimum of energy while a
sequential command controls energy cut-off
and supply. Thus, there is no unnecessary
battery consumption.
A battery lasts the equivalent of 20,000
shutter releases in continuous photography, or
one year under normal use.
