1 Press the mode button to display or on the data panel. 2 Press the select button to blink “HSS.” • The currently selected high-speed sync setting ( / ) also blinks simultaneously. Continued on the next page Applications 35 3 Press the + or – button to select . 4 Press the select button repeatedly until blinking stops. • “HSS” remains on the data panel. • High-speed sync is cleared when is selected with the procedure described above, and a shutter speed faster than the sync speed can no longer be set. • It is recommended that photos be taken in bright locations. When photographing in dark areas the shutter speed will not exceed the sync speed, even when is selected. • The flash range with high-speed sync is smaller than for normal flash photography. Make sure that the subject is within the displayed flash range before taking the photo. • High-speed sync cannot be used with multiple flash or bounce flash in the upwards, left, and right directions. • When using a flash meter or color meter, high-speed sync cannot be used because it interferes with proper exposure. Either select to clear it or select a shutter speed lower than the sync speed. Flash Sync Speed Flash photography is generally associated with a maximum shutter speed referred to as the flash sync speed. This restriction does not apply to cameras designed for high-speed sync (HSS) photography (p. 35), since they allow flash photography at the maximum shutter speed of the camera. Wireless flash mode (WL) Photographs taken with the flash attached to the camera are flat as shown in photo 1. In such cases, remove the flash from the camera and position it to obtain a more three-dimensional effect as shown in photo 2. When taking this type of photograph with a single lens reflex camera, the camera and the flash unit are most commonly connected by a cable. This flash eliminates the need for a cable to transmit signals to the flash unit by using the light of the built-in flash itself as a signal. The correct exposure is determined automatically by the camera. 1 Applications2 Normal flash Wireless flash Wireless Flash Range The wireless flash uses a light signal from the built-in flash as a trigger to operate the off-camera flash unit. Follow the points below when positioning the camera, flash, and subject. • Photograph in dark locations indoors. • If you rotate the flashtube using bounce-flash function (p. 24) so that the wireless control-signal receiver points toward the camera, it will be easier for the flash to receive a signal from the camera. • Place the off-camera flash within the gray area in the following diagram.

If ISO 400 is used the distances must be multiplied by a factor of two (assume a limit of 5 m). • With wireless flash, the flash range is not shown on the data panel. Notes on wireless flash • You cannot use a flash meter or color meter in wireless flash mode because the camera’s built-in pre-flash goes off. • Test flash for the wireless flash is in the currently selected test flash mode. Three flashes occur with and flashes continue for four seconds with . One flash occurs at the HOLD position. • The zoom position for the HVL-F56AM is automatically set to 24 mm. A zoom position other than 24 mm is not recommended. • In wireless flash mode, ADI metering is canceled and P-TTL flash metering is used automatically (p. 34). • Multiple flash cannot be used. • If another wireless flash is being used nearby, you can change the channel using custom settings to prevent interference (p. 52). • When photographing with the wireless flash, the flash may in rare cases go off by mistake due to ambient static electricity or electromagnetic noise. When the flash is not in use, turn it off using the flash ON/OFF button. Attaching and removing the mini-stand • Use the supplied mini-stand when the flash unit is separate from the camera. • You can attach the flash unit to a tripod using the tripod socket holes in the mini-stand. Attachment Removal Applications Continued on the next page 39 [1] Photography with wireless flash Use only an off-camera flash unit, using the light from the built-in flash as a signal. 1 Attach the flash to the camera and turn the power of the flash and camera on. 2 Set the camera to wireless flash. • Whe...
