Using the Autofocus-Assist Light
The diffuser also softens the light, providing an alternative when no surface is available for bouncing the flash
(see
Bouncing Your Flash on page 27).
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 VS-560N will emit a red autofocus-assist beam when you press your camera’s shutter-release
button halfway to autofocus. The camera will then be able to autofocus by locking onto the projected light.
Note that the autofocus-assist light is only available when your camera’s autofocus system is set to AF-A or
AF-S. It is not available when AF-C is selected.
