Using The Autofocus-Assist Light - Bolt VS-510S User Manual

The diffuser also softens the light, providing an alternative when no surface is available for bouncing the flash
(see Bouncing Your Flash on page 26).

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-510S 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.
