FEATURES When this camera is used with any SMC Pentax-A or SMC Pentax-F lens, it offers four exposure modes: Programmed AE, Aperture-priority AE, Metered Manual and Programmed Auto Flash. When the lens aperture is set to "A" position, the Programmed AE mode can be used. When the lens aperture is set to any f-stop other than the "A" setting, the Aperture-priority AE or Metered Manual modes can be used. • When the conventional K -mount lens is used, the camera operates in the Aperture-priority AE or Metered Manual mode. Programmed AE Mode The camera automatically selects the most suitable combination of shutter speed and aperture to obtain correct exposure, simultaneously changing the combination according to the brightness of the subject. This mode is suitable for those who do not want to be bothered by setting exposure controls. Aperture-priority AE Mode When you set the aperture manually, the shutter speed is automatically adjusted according to the brightness of the subject to provide correct exposure. This mode is suitable for taking pictures for which the control of the depth of field is desirable, such as portraits, etc. Metered Manual Mode The combination of shutter speed and aperture is completely up to you. Guided by the meter indication in the viewfinder, you can adjust both controls to obtain proper exposure. If necessary, deliberate over- or underexposure can be obtained. • 2
