PROGRAM – P
The programmed AE exposure control uses luminance and focal-length information to ensure perfect exposures. The sophisticated exposure system allows the photographer the freedom to shoot without having to worry about the technical details of exposure settings. The shutter speed and aperture val- ues of the exposure are displayed on the monitors and data panel. The shutter speed range in pro- gram exposure mode is 4 to 1/4000 second. If the brightness level of the scene is outside the expo- sure control range of the camera, the shutter-speed and aperture displays will turn red.
The program line adjusts with the changes in focal length of the zoom lens. The camera is pro- grammed to maximize depth of field in the wide-angle range to provide sharp landscape pictures, and to maximize shutter speed in the telephoto range to minimize camera shake and blurred images. When the shutter speed falls below an acceptable limit for the camera to be hand held, the camera- shake warning appears in the lower left corner of the monitors (p. 17).
PROGRAM SHIFT
Although exposure calculations can be left to the camera, photographers can still have control over the final exposure with the program-shift function. As described in the basic recording operation (p. 31), press the shutter-release button partway down (1) until the shutter speed and aperture value are displayed. The control dial (2) can then be used to shift the
shutter speed and aperture combination; each combination | 1 |
will give the optimum exposure. | 2 |
The built-in flash cannot be used with program shift. The camera gives priority to the flash exposure; once the flash is raised, any changes made with the program shift will be can- celed.
