The viewfinder is of the single-lens-reflex real-image type. The image visible in the field of view, therefore, is the same as that
exposed on film. This manual was created by www.butkus.org/chinon and should only be found at my site.

DEPTH OF FIELD

When the lens is focused on a subject at some distance, not only the subject but also a certain area around the subject will be
sharply delineated in a photograph, and this area is known as a depth of field and has the following features. 1. The larger the
f-number, the bigger the depth of
field.
2. The farther the distance at which the lens is focused, the bigger the depth of field is.
3. When the lens is focused on a subject, the depth of field is bigger for the section in front of the subject than that behind the
subject.
.4. The shorter the focal length, the bigger the depth of field is.
The depth of field may be ascertained either with the depth-of-field scale or with the manual aperture. As for details, reference
is made to the table of depths of field.
