Distance Scale Depth-of-Field

The Distance Scale is used to determine the film-plane-to-subject distance. The scale itself is composed of two parts, the Distance Scale and Focal Length Scale.

After focusing, the correct distance can be determined by locating the point at which the curved line for the focal length in use inter- sects the Distance Scale.

For example, if the 110 mm lens is mounted on the camera and focused as shown in the illustration, the subject is 1.5 m (5 ft) from the film plane.

Depth-of-Field Preview

1.Set the Aperture Ring to the desired f-stop and focus the lens.

2.Depress the Depth-of-Field Preview Lever of the lens and you will be able to check the depth-of-field directly on the focusing screen.

Using the Depth-of-Field Scale

1.Check the camera-to-subject distance on the Distance Scale.

2.Rotate the Lens Distance Scale Knob until the previously noted camera-to-subject distance is aligned with the center index of the Depth-of-Field Scale.

3.Locate the selected aperture on both sides of the Depth-of-Field Scale.

4.The figures of the Lens Distance Scale, appearing above the selected aperture, indicate the nearest and furthermost limits of sharpness for that aperture.

For example, when the 110mm lens is focused at 3 m and stopped down to f /32, everything from approximately 2m to 10m will be in focus.

When desiring to know the depth-of-field in feet, rotate the Lens Distance Scale 180°, as one side is in feet and the other in meters.
