Setting the Parallax Correcting Dial
By turning the parallax correcting dial ( 23 ), set the dial index to the focal length
of the lens used. Subsequently, while the lens is be i ng extended, the pointer will
appear on the upper, left portion of the focusing screen. The position of this . T'
pointer indicates parallax and the exposure factor .

Correcting parallax:
When the pointer appears on the focusing screen, the upper portion visible abo l( e
the pointer will be cut off on the film . Be sure that the subject is satisfactorily ~
appears under the lower portion of this pointer. When using the camera on a
tripod , use the Paramender (parallax corrrecting device) to ensure that the camera
photographs
the same image viewed on the focusing screen through si mple
operations.
Compensating exposure:
As distance between the lens and film increases, image brightness on the film is
reduced even
though aperture size ,remains the same. Consequently, it is necessary
to increase ' the exposure.
The
figures on the focusing screen left side indicate the exposure fa c tor. Com-
pensate the exposure after reading the figure indicated by the pointer while focusing.
For instance, assuming
that the correct exposure value measured by an exposure
meter is 1/ 125 sec. at fi ll , compensate the exposure as follows:
If the pointer indicates 2, 1/ 125 sec., f/ 8
or 1/ 60 sec ., fi ll
If the pointer indicates 3, 1/ 125 sec ., between tl 8 and f / 5.6
or 1/60 sec., between ti ll and tl 8
