600 Series Camera Split-second focusing (Sun 660 AF only) When you take a picture, your camera sends sound waves, at frequencies beyond our range of hearing, to the central part of the scene (approximate area circled in white). At the same time, an internal disk with four lenses (behind the fixed front lens) starts to turn. In a split second, a tiny electronic computer measures the time it takes for the sound to reach your subject and the echo to return, and calculates the distance between the camera lens and your subject. The lens then will put your subject into sharp focus at that distance and lock into place. User Guide To take a darker picture, slide the control past the black arrow. Return the control to center position when you have finished reshooting. A white double arrow appears in the bottom of the viewfinder as a reminder that the control is not in its center position. Lighten/darken control Use this control only when you want to reshoot a picture to make it lighter or darker. To take a lighter picture, slide the control past the white arrow.
