Attachment and
Removal
of
Film
Backs
The
film
back
is
a
film
cham-
ber
that can
be
attached
or de-
tached
f
reely
f
rom
the main
body,
thus
permitting
f
ree
ex-
change
of
f
ilrn types,
at
all
times.
Since
the
main
body and
film
back
are
always
fully
cou-
pled,
upon
connection,
always
turn
the
film
winding crank
completely
one time, upon at-
taching
the
film
back. lf wind-
ing
is
not
possible,
all
prepara-
tions
for
taking
the
picture
have
been
completed.
lf winding is
possible,
however,
rotating
the
f ilm
winding
crank
until it
stops
automatically
takes care
of the
incompleted
action, whether
un-
cocked
shutter
or
film
not
ad-
vanced.
Th is
means, of course,
that
it's
possible
to choose the
film type
most
suited
for
the
shot,
even
midway
in
a roll.
An
ASA/ISO
f
ilm speed
dial
and
an
exposure
compensation
dial
are
available
on the
film
backs.
When used
for
setting the
film speed
of the
film
loaded
in
the
film
back, there is auto-
matic
coupling
when
f
inders
with
built-in
exposure
meters
are
attached
on
the main
body.
This
will, of course,
be
very
con-
venient
when
using
films
of dif-
ferent
sensitivities in
the
film
backs.
iF
Make
full
use of
film
back
in-
terchangeability, in
the
f
ollow-
tng
manner:-
1.
Take
full
advantage of
the
multi-format
superiority
of
the
GS-l
and use
film
backs
in
many
different
formats,
wh ich
will
not
only
give
you
different
effects but will economize on
f ilm.
2. Take
\/our
pictures
in
color
and
black-and-white,
and
in
dif-
ferent
film
speeds, as required.
3.
Keep a sufficient
guantity
of
preloaded
film
backs
on
hand
and speedy, continuous
shoot-
ing
will be
possible.
4. Don't waste
unsuitable
film
used
in a
previous
session but
simply
load
up
a new
film
back
with
the
required
film
type.
5.
The
Polaroid
Film
Back
can
be used
for
instant
color or
black-and-white
pictures,
when
in
a rush, or
used
for
checking
composition
or
lighting
effect,
before
taking
the
actual
picture.
{F
Film
backs are avaifable
op-
tionally
and
the
type meeting
the
requirernents
of
the
photog-
rapher
should
be chosen.
