User manual PENTAX AF200FG FLASH

[. . . ] Although we have carefully produced this flash unit for safe operation, please be sure to especially follow warnings and cautions given on page 1. This symbol indicates that violating this item could cause serious personal injuries. This symbol indicates that violating this item could cause minor or medium personal injuries, or material losses. Do not attempt to disassemble the flash unit yourself, as there is danger of an electric shock. [. . . ] Slide the hot shoe foot of the flash unit into the camera's hot shoe from the back of the camera forward. Turn the locking lever of the flash unit in the direction indicated by (FIX) to lock it. PENTAX digital single lens reflex cameras can accept a shoe lock pin. When attaching the flash unit, turn the locking lever in the (FIX) direction and lock the flash unit to the camera with the shoe lock pin. When releasing the flash unit, be sure to do so after turning the locking lever in the direction opposite to that indicated by (FIX) and loosening the shoe lock pin. Using the mode dial located on the rear side of the AF200FG, you can set the following flash modes. 5), or (­1), the operating mode of the flash unit is automatically switched to P-TTL Auto or TTL Auto by communicating with the camera you use. When the mode dial is set to (FULL), the flash unit always discharges at its full output regardless of the ambient light condition. Of the flash unit based on the ISO sensitivity setting of the camera, then calculate the aperture value according to the flash range. This mode is available on all the cameras for which you can set the desired aperture. A pre-flash is discharged before the main flash so that the metering sensor in the camera can measure the condition of the subject and adjust the output of the main flash properly. When the lens you use is equipped with the lens aperture ring, set the position of the ring to A (You do not need to do this for the DA or FAJ lens). When you use the cameras that support both P-TTL and TTL modes (*ist DS2, *ist DS, *ist D) , if the aperture of the lens is in a position other than A, you can shoot in TTL Auto flash mode. Be aware that for the cameras that only support P-TTL Auto flash, the flash unit does not adjust the flash output but discharges at full output, if the aperture of the lens is in a position other than A. Confirm that the subject is within the effective flash range and the ready lamp is lit, and take a picture. The correct flash output is obtained in P-TTL auto mode only when the flash unit is used with auto-focus lenses. With single lens reflex cameras (film cameras) other than PENTAX digital single lens reflex cameras, you can perform auto flash shooting if they support TTL Auto. (However, the 645 format cameras before SF series and of the early type do not support the TTL Auto) (Unit: m) * You can check the approximate range of distances within which the flash unit can adjust the flash output (and the appropriate exposure is available) based on the combination of the ISO sensitivity setting on the camera and the aperture value from the above table when the mode dial is set to (AUTO). (The values in "Wide Panel" line indicate the range when the wide-angle panel is used. 5 m, sensitivity is ISO 100, and the wide-angle panel is not in use, the calculation will become as follows: The Guide No. Measure the distance to the subject (between the AF200FG and subject) and determine the aperture value using the following procedure. The appropriate shooting distance (distance at which the appropriate exposure is available) is determined based on the combination of the ISO sensitivity setting and the aperture value on the camera when the mode dial is set to (FULL).
