0 F-"E rirnx MID k • 36 "DEDICATED" AUTOMATIC FLASH UNITS The Pentax AF200S and AF160 Automatic Electronic Flash Units are fully compatible with the LX camera's automatic shutter speed flash synchronization and viewfinder flash ready light features. When the flash unit is turned "ON" with the camera's shutter dial set at "Automatic" and the flash unit set for auto flash operation, the shutter automatically synchronizes at 1/50 sec. and the "X" indicator inside the viewfinder glows when the flash unit reaches full charge. NOTE: Dedicated flash is also offered with the above two units with the shutter dial set to "X." The AF200S also features flash exposure override. When the viewfinder indication for the camera's metering system is between 1/30th second and 4 seconds (occasionally 1/60th second, due to stepless metering) flash synchronization is automatically obtained; when faster speeds are indicated, however, non-flash exposure system overrides flash, preventing overexposure. (This feature is not offered with the AF160).
