Depth of Field
Depth of field refers to the zone of acceptable

i focus extending in front of and behind the

plane of sharpest focus. As this zone is excep
tionally shallow at high reproduction ratios,

previewing is desirable before shooting. To
preview, press the depth-of-field button on

the camera and the lens will close to the

preselected aperture to allow you to see how

much background and foreground is in focus.

Depth of field can also be observed by reading

the color-coded indicators inscribed on the
lens barrel. The pairs of colored lines on either

side of the white distance scale index line
correspond to f/numbers of the same color on

the aperture scale. At close distances, so little

is in focus that the depth-of-field tables on
pages 13 ~ 14 are more useful.
