ZOOMING C
Zooming operation is performed by sliding the focusing/zooming control ring in or out
until the desired degree of magnification (or composition) is obtained. To facilitate set-
ting the lens at a desired focal length, reference marks corresponding to focal length
settings of 180mm, 200mm, 250mm, 300mm, 350mm, 400mm, 500mm and 600mm
are provided. Of course, all intermediate focal length settings can be used.
DEPTH-OF-FIELD SCALE
Depth of field (i.e., the zone of acceptable image focus) can be checked by reading the
curved, color-coded depth-of-field indicators engraved on the lens barrel. The pairs of
colored lines on either side of the white distance index line correspond to f/numbers of
the same color on the aperture scale. You can also observe the depth of field through
the viewfinder by simply pressing the depth-of-field preview button on the camera
body.
