a
focusing
aid

of a
split-image spot su rrounded 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 microprism
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.

probab ly

focusi ng is easiest if:

it-image
spot

subjects having vertical
lines.

medium
telephoto,
especially

su
bjects not having vertical
lines
