Flash Mode - Sony a9 Instruction Manual

• Do not use the Multi Interface Shoe with a commercially available flash that
applies voltage of 250 V or more or has the reverse polarity of the camera.
Doing so may cause a malfunction.
• You can use a flash of the reverse polarity with the Sync Terminal. Please use
a flash with a sync voltage of 400 V or less.
• When shooting with the flash and the zoom is set to W, the shadow of the
lens may appear on the screen, depending on the shooting conditions. If this
happens, shoot away from the subject or set the zoom to T and shoot with
the flash again.
• The corners of a recorded image may be shaded, depending on the lens.
• When shooting with an external flash, light and dark stripes may appear on
the image if the shutter speed is set to faster than 1/4000 seconds. If this
occurs, Sony recommends shooting in the manual flash mode and setting the
flash level to 1/2 or higher.
• For details on compatible accessories for the Multi Interface Shoe, visit the
Sony website, or consult your Sony dealer or local authorized Sony service
facility.
