Amplifier In a Single 1C

The silicon photocell is well known for its

outstanding photosensitive characteristics.

The AE-1 has a logarithmic amplifier and

a special, immediate response circuit, inte­
grated into a single 1C in order to obtain the

speediest responsiveness while at the same

time ensuring remarkable overall durability.

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.
