Asahi Pentax ES Operating Manual Excerpts

EXPOSURE FACTOR CONTROL DIAL

The scale (4x 2x 1x 1/2x ) indicates exposure factor

Turn the outer ring of the film type dial, and set 1x against the orange arrow for normal exposures.

Use this control only when necessary to give intentional over- or under-exposures within the range of these factors while working on "AUTOMATIC". For example, set the dial at 2x or 4x when shooting against the light, and at 1/2x against dark backgrounds. In addition, the dial can be set between the indicated positions to achieve more specific exposure control.
