Depth-of-Field Preview/Film Plane Indicator
Changing Focusing Screens
Composition
•Depress the depth-of-field preview button to confirm the depth of field
through the viewfinder (see page 68).
•Pressing the depth-of-field button stops the lens down to the aperture
controlled in Programmed Auto or Shutter-Priority Auto exposure mode, and
down to the aperture selected in Aperture-Priority Auto or Manual exposure
mode. By looking through the viewfinder, the approximate depth of field with
the given aperture can be confirmed.
•The film plane indicator shows the position of the film plane inside the
camera body.
•The film plane indicator shows the standard line of the shooting distance and
indicates the position of the film plane inside the camera body. Use this
indicator when actually measuring camera-to-subject distance, e.g. in close-
up photography.
•The exact distance from the lens mounting flange to the film plane is 46.5mm.
•In addition to the B-type BriteView screen supplied with the F100
camera, an E-type clear Matte/Fresnel screen with grid is available as
an option. This screen is suitable for copying and architectural
photography.
