Now, does anyone know why Olympus used CdS for the prism
meter and silicon blue cells for the off-the-film automatic metering?
I expect it is because of the speed required for the TTL metering system.
Whilst I daresay you
could design a CdS device to give the response time needed, they probably put
the camera together using standard off-the-shelf devices, and these were
probably too slow.
