The power zoom function
When the SB-600 is used with cameras compatible with CLS, digital SLRs not
compatible with CLS, and cameras in Groups I to II in combination with a CPU lens,
the power zoom function activates and the zoom head is automatically adjusted.
• The zoom-head position is automatically adjusted to match focal lengths of 24mm,
28mm, 35mm, 50mm, 70mm and 85mm when the power zoom function is activated.
• When the lens focal length is not one of those indicated above, the zoom head adjusts to
the closest wide-angle setting of the lens in use. For example, if the zoom setting of a CPU
lens was between 36mm and 49mm, the zoom-head position would be adjusted to 35mm.
• If a small M does not appear above the “ZOOM” indication on the LCD panel, the zoom-
head position will be automatically adjusted. If a small M appears, keep pressing the
s button until it disappears.
