AF200T, AF280T, and AF400T • If the TTL auto mode is selected, these flash units can be used for daylight-sync shooting, because the shutter speed is adjusted (1/250 to 1/60 second) according to the ambient brightness. • When using the Three-Level Auto (red, green, and yellow settings) mode, the aperture value is adjusted as shown in the table and the shutter speed also varies within the range 1/250 to 1/60 second. Red Green Yellow F200T f /2.8 f /5.6 A280T' - '''i!if4.0O:r f/4 f/4 f/8 f/8 f /11 (ISO 100) Notes on the Use of Pentax Dedicated Flash Units 1) When using a type D flash unit in the MS (Manual Sync) or M (Manual) mode, adjust the aperture according to the calculator board on the back of the flash unit. 2) A Pentax dedicated flash unit has priority over the built-in flash unit when both are used. Before releasing the shutter, make sure that both flash units are charged. Contrast-Control Flash Photography Using the AF330FTZ 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 the two units. The AF330FTZ gives out twice as much light as the built-in flash unit. 1. Put the AF330FTZ in the contrast-control flash mode. 2. Ensure that both flash units are charged and then shoot. * Separating the AF330FTZ from the camera increases the effect of contrast control. Use an optional "Hot m Shoe Adapter F" (two) and "Extension Cord F5P." 0 0 m If an accessory with a different number of contacts 7:1 is used, such as a Hot Shoe Grip, a malfunction may z0 occur. (i) • In the contrast-control flash mode, the shutter speed is fixed at 1/60 second. However, a shutter speed of 1/60 or slower can be set in the Hyper Manual mode, the Shutter-Priority AE mode, or the Shutter-Priority AE mode switched from the Hyper Manual mode. 49
