Using the Autofocus-Assist Light

Camera autofocus systems can have difficulty locking onto a subject in dim light. When the ambient light level 
is low, the VX-760C will emit a red autofocus-assist beam when you press your camera’s shutter-release 
button halfway in order to autofocus. The camera will then be able to autofocus by locking onto the projected 
light.

Note:

 The autofocus-assist light is available only when your camera’s autofocus system is set to One Shot or 

AI Focus. It is not available when AI Servo is selected.

Bouncing Your Flash

The VX-760C flash head can tilt down to -7°, and up at 45°, 60°, 75°, and 90° angles to the lens. It can also 
swivel horizontally 180° to the right and 90° to the left.
