Pentax P30T - Focusing; Focusing Methods; Diopter Adjustment

You
can
focus in three ways,
with
the
split-
image,
microprism, and/or
matte
field.
To
focus
using
the
split-image,
turn
the
focuslng ring
until
the two
images
in
the
split-image circle
at
the center
of
the
focusing screen are
perfectly
aligned.
When using
the
microprism
collar,
focus
until
the
glitter
disappears
from inside the
collar.
With the
matte
field,
focus
until
the
image
on
the
matte
field
appears
sharp
and
crisp.
Note:
lf the
maximum aperture
of the attached
lens
is
smaller
than
f/5.6
(for
example,
f
lB
as
in
the case
of a
long
telephoto),
it
is
easier to
focus
on
the
matte
f ield
since
the
split-image
and
microprism collar
areas
become
much too
dark
for
satisfactory
focusi ng.
