• When using the Three-Level Auto (red, green, and yellow settings) mode, the aperture value is adjusted as shown in the table. When the flash is fully charged, the shutter speed also varies within the shutter speed range of 1/100 to a slower speed which does not cause camera shake. The slowest shutter speed varies according to the lens focal length. When a nonautofocus lens or the Action Program Mode is in use, the shutter speed will be set to 1/100 of second. Red Green Yellow AF200T f/2.8 f/5.6 AF2807 f/4 f/8 AF400T f/4 f/8 f/11 with ISO 100 Notes on Pentax dedicated flash units When the built-in flash is used in combination with a Pentax dedicated flash unit, if the trailing-shuttercurtain sync mode is set for the dedicated flash unit, the built-inflash also operates in the trailing-shutter curtain sync. mode. Ensure that both flash units are fully charged before releasing the shutter. Contrast-Control Flash Photography Using the AF330FTZ or AF500FTZ in combination with the built-in flash allows twin flash photography (contrast-control flash photography). This is based on the difference between the amount of light discharged from two units. 1. Put the AF500FTZ or AF330FTZ in the ContrastControl Sync Flash Mode. 2. Ensure that both flash units are fully charged and then shoot. • The ratio of the amount of flash light is 1 (built-in flash) : 2 (dedicated flash unit). • When the AF500FTZ or AF330FTZ is used off the camera, the effect of contrast control is increased. Use an optional "Hot Shoe Adapter F" (uses two pcs. for the AF330FTZ) and "Extension Cord 5P" to connect the dedicated flash unit to the camera. Do not combine an accessory with a different number of contacts such as a "Hot Shoe Grip" as a mulfunction may occur. • In the Contrast-Control Sync Flash Mode, the top flash sync speed is 1/60 of second.
