Controlling Flash Coverage (Zoom)

The VS-570F’s angle of coverage can be adjusted (“zoomed”) to match the focal length of your lens, so that

your image is evenly illuminated from edge to edge.

When the ash zoom setting is adjusted, the position of the reectors inside the ash head shift in order to

make the angle of coverage wider or narrower.

The available zoom positions are 24mm, 28mm,

35mm, 50mm, 70mm, 85mm, and 105mm.

Automatic zoom control: When you turn the VS-570F

on, the zoom mode indicator on the LCD will show an

A to indicate that it is in automatic mode and at the

default 35mm position. When you press the shutter-

release button on your camera halfway to initiate

communication between the camera and the ash, the ash zoom will adjust to match the lens focal length

and the closest zoom setting will be displayed on the LCD. If you zoom your lens, the ash zoom setting will

change automatically.
