:TRAILING-SHUTTER-CURTAIN SYNC FLASH 7 In normal electronic flash photography, the flash discharges at the instant the first shutter curtain completes its travel. This is referred to as the leading-shutter-curtain sync flash. In the trailingshutter-curtain sync flash mode, the flash is discharged at the instant the second curtain begins its travel. This mode will freeze the subject with a blur appearing before the subject under a slow shutter speed condition. Using a leading-shuttercurtain sync flash will freeze the subject with a blur appearing after the subject. Procedure 1. Set the main switch to Ell . 2. Set the sync mode switch to the TRAILING SHUTTER CURTAIN [-i] position. 3. Set the zooming position according to the lens in use. • With an FA or F lens, the [A.ZOOM] setting automatically adjusts the zoom position. 4. Confirm the flash Ready lamp is lit and then discharge the flash. • With the trailing-shutter-curtain-sync flash, the [TTL] mode is automatically set even if the TTL mode has not been set on the flash unit. • The built-in flash on the Pentax SLR cameras other than the Z-1 /PZ-1 does not feature the trailing-shutter-curtain capability: it does not discharge when combined with the AF50OFTZ. • When the camera's exposure meter is switched ON, the trailing-shutter-curtain-sync mode will be automatically set on the flash unit. 19
