The camera's focusing screen has
a focusing aid consisting of a
split -image spot surrounded by a
band
of microprisms in the center
of an Acute Matte field .
To focus the camera visually, look
through the viewfinder and turn the
lens' focusing grip until :
•
Upper and lower subject images in
the spot are exactly aligned with
no broken lines between them .
• Subject image in
the band does
not shimmer or appear broken up .
At this point , the subject image
within the viewfinder 's center
focusing aid appears clearest and
seems
to blend with that on the
matte field surrounding it .
You will probably find that
focusi ng is easiest if :
• Split-image spot
is used for
subjects having vertical lines.
•
Microprism band is used for lenses
from medium wideangle through
medium telephoto, especially
with subjects not having vertical
lines.
•
Matte field is used for longer
focal-length lenses
or for macro or
other work involving considerable
lens extension.
