Program Line

The program line below applies when the camera is used in the

Program AE mode with an EF 28-90mm f/4-5.6 lens.

— : At 28m m focal length

: At 90m m focal length

Program Line Description

The bottom horizontal axis represents the shutter speed and the right
vertical axis represents the aperture. On the left edge and top edge of the

graph, the Exposure Value (EV) is indicated for the respective shutter
speed and aperture combination set by the Program AE mode and denoted

by the program line.

Example: When the 28mm focal length is used and the subject brightness

is EV 13, the point where the diagonal line from EV 13 (on the top edge of

the graph) intersects the program line indicates the corresponding shutter

speed (1/125 sec.) and aperture (f/8) which the program sets automatically.

The arrowhead lines above the graph indicate the metering range for the

respective film speed.
