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 f ield 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 .
