Using the Autofocus-Assist Light - Bouncing Your Flash
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-570N 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.
Bouncing Your Flash
Using flash to directly illuminate a subject often creates harsh, unnatural, and unattractive shadows. To avoid
this, the flash can be tilted or swiveled, allowing you to aim your flash at a large white or neutral-colored
surface, such as a ceiling, a wall, or a reflector. The light will bounce off of the larger surface before striking
your subject, providing softer, more natural illumination.
