Sony DSLR-A900 User Manual

• For details on High Speed Sync, refer to the operating instructions supplied with the 

flash.

• You can use a flash equipped with a flash sync terminal of the opposite 

polarity.

Notes
• Select the manual exposure mode and set the shutter speed to 1/200 second with the 

SteadyShot on or 1/250 second with the SteadyShot off. If the shutter speed 
recommended on the flash is slower than that, use the recommended speed or an 
even slower speed.

• Use a flash with a flash sync voltage of 400 V or less.
• Before you connect the flash sync cord to the   (flash sync) terminal, turn off the 

power of the connected flash. If the power is on, it may flash when you connect the 
cord.

• The flash will always be full emission. Flash compensation (page 73) cannot be 

used.

• Using auto white balance is not recommended. Use custom white balance to gain 

more precise white balance.

• The flash indicator is not displayed when the   (flash sync) terminal is plugged in.
