Note: The sonar rangefinder has a much smaller “depth of field”, or distance zone within
which it signals that the subject is at the correct distance. When the camera is set for
1.2m, this range is approximately 5 in. (12.7cm) and the subject can be 44.5-49.5 in.
(1.13-l.26m) away. When set for 1.92m, the range is approx. 7 in. (17.8cm), and the
subject can be 71-80 in. (1.8-2.0m) away. A small change in distance, such as when
the subject leans forward slightly, may cause the rangefinder to signal that the camera
is too close, although the subject is still well within the camera’s range of sharp focus.
The rangefinder’s “depth of field” is not affected by the lens aperture.
increases as you close down the lens
aperture. Thus, you should always use the
smallest possible lens aperture (highest
possible f-number).
The table shows the approximate depth of
field at the various f-number settings.
