Shoot the image.
The flash of the HVL-F58AM and another flash are fired.

Notes
• Change the channel of the external flash when another photographer is using a 

wireless flash nearby and his/her flash light triggers firing of your flash. To change 
the channel of the external flash, refer to the operating instructions supplied with it.

• For details on the wireless flash, refer to the operating instructions supplied with the 

flash.

If you use the slow sync shooting feature with a slower shutter speed, you 
can capture a clear image of both the subject and the background. This is 
convenient when you shoot a portrait at night with a dark background.

Note
• In shutter speed priority mode or manual exposure mode, slow sync shooting is not 

available using the SLOW SYNC button.

Since the flash sync speed restriction is removed when you use one of the 
HVL-F58AM, HVL-F56AM, HVL-F42AM or HVL-F36AM models, the 
flash allows you to take pictures using the flash with the entire shutter 
speed range of the camera. It also enables you to take pictures with the flash 
in bright conditions with the aperture open. In high speed sync mode, “H” 
or “HSS” appears in the viewfinder and on the LCD monitor.

Notes
• High speed sync mode is not available when the two-second self-timer or mirror 

lockup shooting is selected, or the flash mode is set to 

 (Rear sync.).

Shooting with Slow Sync

 in the viewfinder and on the LCD 

monitor lights up to indicate the exposure 
is locked.
