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. Numbers in the scale
are in F values, and for example, if the shooting
distance is 1.5m and the aperture is f/8, the
sharp area will extend from about 1m to 3m.
The infrared index corrects the focus setting
when using monochrome infrared film. Focus on
the subject, then adjust the distance setting by
moving the focusing ring to the corresponding
infrared index mark.

Some EOS cameras cannot use infrared film. See
the instructions for your EOS camera.

The depth-of-field scale is only valid when the
tilt scale is set to the “0” position.

The depth-of-field scale is an approximate
indicator.
