5. Depth-of-Field Scale
The depth of field is the distance in front of and
behind the plane of focus on the subject that
appears sharp. The depth of field is indicated by
the area between the depth-of-field scale lines
below the distance scale. The numbers on the
scale are F values, and for example, if the
shooting distance is 0.5m and the aperture is
f/16, the area in focus will extend from about
0.3m to infinity.
The depth-of-field scale is an approximate
indicator.
The infrared index corrects...
