The automatic part of this camera no longer works so I thought I would find out why. It turns out that the selenium cell that is around the lens is no longer generating any voltage. It’s a very simple system where the voltage from the selenium cell deflects a needle connected to a small coil “galvanometer”. As the shutter is pressed there are two plates that move upward, on the top of these plates are steps that determine how far the plates slide based on where they intersect the needles horizo
