Using Depth-of-Field Scale on Lens:
On the Depth-of-Field Scale, f/stop markings identical to those on the Manual Aperture Scale (7), are repeated
to the right and left of the Distance Scale Index Mark (46). The Depth-of-Field for any focused distance will be
found between any two identical f/stop markings on the Depth-of-Field Scale. Thus, if the lens is focused at 15
feet and the picture is to be made at f/16, referring to f/16 on both sides of the scale tells us that the Depth-of-
Field extends from Infinity to about 8 feet. For maximum Depth-of-Field including Infinity, set the Infinity
mark at the f/stop in use, on the right hand side of the scale.
Film Plane Mark: For certain highly specialized applications, it is sometimes desirable to place your subject at
a specific distance from the film (focal) plane. Should you wish to do this, measure the distance from the center-
of-interest of the subject (the part you'll focus on) to the Film Plane Mark "my" (16) atop the camera body.

Infrared Film Compensation Mark: Infrared rays come to a different focus than visible light rays. When
shooting infrared film with the appropriate filter, focus as usual. Then bring the distance figure opposite the
Distance Scale Index Mark (46) into line with the Infrared Film Compensation Mark (47).
FILM REWIND AND UNLOAD
After all the pictures on the roll have been taken, the film is rewound into the cassette prior to removal for
processing.
An occasional look at the Film Counter (2) will help keep you posted as to when you are coming to the end of
the roll and prevent your accidentally tearing the film out of the cassette. If you should come to the end of the
film while the camera is at your eye in shooting position, the Film Transport Lever (11) will tighten and refuse
to advance even ff the shutter has been released. If this happens do not force it! Instead, depress the Film
Rewind Button (35) and at the same time move the Film Transport Lever as far as it will go. It will then snap
back into its normal position. Then, just ...
