uncovers
the
finder, places a 45°
mirror
behind
the
camera lens, and
reflects
the
image
to
a ground-glass. When using
the
sliding magnifier
of
the
reflex finder,
the
eye
should
be
not
more
than
two
inches from
the
lens
of
the
magnifier.
Example
of
a
"close-up"
where the reflex
finder
is
required.
The
mirror
blocks
the
light
path
from
lens
to
film, therefore:
The reflex ftndercannot
be
used while' the 'camera
is
running:.;'N 0.v
er

< ".<'-" \
WHen
the
camera is
-
S;tar~ed,
the
reflex finder
is covered and
the
mir-
ror
drops
down
auto-
matically; the finder
cannot
be closed
until
the
camera is started.
COMPOSING:
The
field can be determined before
making
the
exposure
to
obviate
parallax
correction for" close-ups ...
If
the
image is dim, open
the
lens
diaphragm
to
its largest
stop
while
composing and focusing.
FOCUSING:
The
simplest, quickest
method
of
focusing, whenever
there is ample
depth
of
focus, is
by
estimating
the
distance and
setting
the
focusing scale.
When
depth
of
focus is
at
a minimum, however,
it
is a
great
ad-
vantage
to
focus visually
with
the
reflex finder. Average
depth
is
lacking
(1)
when
the
subject is very close, and (2)
when
using
the
telephoto lenses.
To
focus visually,
open
the lens diaphragm
to
its
largest opening.
Turn
the focusing collar
until
the
image on
the
ground-glass is critically
sharp. Then set the diaphragm as required for exposure.
When focusing visually,
it
is extremely
important
to
go
through
the
focus several times
to
attain
the
sharpest image possible,' choose a
portion
of
the
finder image
that
will
show
fine detail, such as
hair,
weave in
fabric, etc.
