Focusing the Lens
When the lens has been focused, the double
image superimposing rangefinder produces
two superimposed images with in the square
of the viewfinder.
How To:
1. Position the subject within the central
square of the viewfinder. As on the top left
the subject will appear as a double images.
2. Rotate the focusing ring until the two
images converge and are superimposed as
on the figure on the left. The lens is now
focused.
The two images can also be superimposed
by using the lateral boundary line between
the viewfinder and the center rectangle zone
or split image.
Adjust the images until the boundary lines
converge.
[Photographic area covered]
Within the viewfinder the subject area covered
is indicated by the visible bright frame.
Parallax is automatically compensated for
according to the subject-to-lens distance.
The composition will be within in the lines of
the bright frame “A” for 6 x 7 format and “B” for
135 panoramic format. 83% of the field of view
is visible at infinity and 100% is visible at the
minimum focusing distance. The appropriate
bright frame area is automatically indexed
upon lens interchange.
