Zoomingc, DEPTH-OF-FIELD Scale, Specifications

ZOOMINGC

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.
