Shifting the Program
In Program AE mode, you can freely change the shutter speed and aperture value combina-
tion (program) set by the camera while maintaining the same exposure value. This is called
shifting the program.
To do this, press the shutter button down halfway, then turn the < > dial until the shutter
speed or aperture value you want is displayed.
● Once you take a picture with the shifted program, the shifted program is canceled automati-
cally and the original program is restored.
● If you are using a flash, you cannot shift the program.
