FOCUSING You can focus in three ways, with the split-image, microprism, and/or matte field. To focus using the split-image, turn the focusing 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: If the maximum aperture of the attached lens is smaller than f/5.6 (for example, f/8 as in the case of a long telephoto), it is easier to focus on the matte field since the split-image and microprism collar areas become much too dark for satisfactory focusing. Diopter adjustment for viewfinder eyepiece People who wear eyeglasses due to myopia, hypermetropia or presbyopia, sometimes find it difficult to focus while wearing their glasses. In this case, use the accessory diopter correction lenses M (See page 53). 25*

FOCUSING
You
can
focus
in
three
ways,
with
the
split
-image,
microprism,
and/or
matte
field.
To
focus
using
the
split
-image,
turn
the
focusing
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:
If
the
maximum
aperture
of
the
attached
lens
is
smaller
than
f/5.6
(for
example,
f/8
as
in
the
case
of
a
long
telephoto),
it
is
easier
to
focus
on
the
matte
field
since
the
split
-image
and
microprism
collar
areas
become
much
too
dark
for
satisfactory
focusing.
Diopter
adjustment
for
viewfinder
eyepiece
People
who
wear
eyeglasses
due
to
myopia,
hypermetropia
or
presbyopia,
sometimes
find
it
difficult
to
focus
while
wearing
their
glasses.
In
this
case,
use
the
accessory
diopter
correction
lenses
M
(See
page
53).
