© Special Features

1. The PD Prism Finder is an eye-level finder with a built-in
silicon photo diode exposure meter and electronic shutter
control circuit.

2, The PD Prism Finder offers complete coupling of the lens
‘aperture, shutter speed, and film speed (ASA).

3, Seven LED's are built into the viewfinder system. A yellow-
‘green LED indicates correct exposure and red LED's indi-
‘cate over, under, and compensated exposure.

even in dim light, and has rapid response because it utilizes
silicon photo diodes.
