Program Ae Control Scale - Contax 159MM Instruction Manual

Shutter speed
(Program AE Control Scale)
The aperture and shutter speed combinations available in
the Normal Program, High-speed Program, and Low-speed
Program AE modes are as shown in the accompanying
scale. When the matching aperture is within the working
shutter speed range oI 111000 sec in the High-speed
Program and of 1/60 sec. in the Low-speed Program
modes, the shutter speed LEDs will pulsate at the
respective shutter speeds.
lf a lens with a different maximum aperture is used, the
working range will vary by the extent of the light value
difference For example, if an 1112.8
lens is used. its

Even when the aperture ring is at a setting other than
minimum aperture, the camera will still operate in the
program AE mode. However, in this case, the camera-
selected shutter speed will work within a narrower working
range between whatever smaller aperture you have
selected and the maximum aperture of the lens, causing
the camera-selected shutter speed to shift under intense
lighting conditions. For example, when set at f/g, the
working range will be narrowed as shown by the dotted
