Common Functions of TTL Auto Flash and Programmed Auto Flash Modes In the Metered Manual mode, slow-shutter speed synchronization can be used by selecting a shutter speed between 1/60 second and one second. The shutter speed can be selected by sliding the select switch to the [ •] or [v] position until the desired speed appears on the CENTIC panel. • When the shutter speed is set between 1/4000 second and 1/250 second, it is switched to the flash-sync speed of 1/125 second when the flash is fully charged. Flash Confirmation Signal (5 ) When a proper flash exposure is made in the TTL Auto Flash or Programmed Auto Flash mode while the camera is set in an AE or Metered Manual mode, the flash-ready indicator ] in the viewfinder confirms it right after the discharge, either by disappearing for a moment and coming back on again or by blinking. * The A F200SA does not have the flash confirmation signal function. Precautions for Using Pentax Dedicated Flash Units • When using a flash unit in the manual sync (MS) or manual (M) mode, select an f-number using the lens aperture ring. If the ring is set at the "A" position, a correct exposure cannot be made. The functions in the MS and M modes may vary depending on the type of flash used, so check the operating manual of the flash in use for details. • Multi-flash photography in the TTL Auto Flash mode can be done by combining the RTF with the AF400FTZ. In this case, the AF400FTZ attached to the camera's hot shoe has a priority for different functions over the RTF. When combining conventional dedicated flash units, use the lens aperture ring to select the aperture. Be sure to check the flash-ready indicator of the attached flash unit before shooting. • The TTL Auto Flash or Programmed Auto Flash mode can be used even when the camera is set at the "125" (1/125 sec.) or "B" (bulb) settings. 43 •
