Unique Motor Drive Coupling System
The
CONTAX
RT
S
is
perhaps
the
on ly SLR
came
ra
on
the
market today
that
affords
fully
automatic exposure even when
the
motor drive
unit
is
used
in any
mode of operation.
This
unique advantage
is
assured because
the
camera
incorporates
an electromagnet ic
release
system of
an origin al
design
When
the
mag netic
release
system
is
act ivated
and
the
exposure
is
completed,
the
motor
drive
switch
built into the camera
body makes
co
ntact
automat
ica
lly, thus
transmitt ing a signal
to
the
motor drive unit
that
the
came
ra is
ready
for film
wind.
In
other
words,
the motor drive will
not
funct ion to advance the
film
unless
the
exposure
is
com
pleted.
This
ar rangement enables the
photographer to resort to fully
automat
ic
ex-
posure,
regardless
of
the
mode of operation of
the
motor drive
unit
or
the
co
nditions
su
rr
ound
ing
the photographic
subject
To
the CONTAX RTS,
t he
motor
drive unit
ca
n
be
likened
to an electr ic d istribut ion panel
to
wh
ich
any type of off-hand
co ntro
l
accessory
ca
n
be
co
nnected
for efficient off-hand
control
of the
shutter operation.
The
motor drive
unit
ca
n
be
set
for either
one of
the two modes of operation.
When adjusted
f
or
single
frame film
drive, it provides automat
ic
film
w ind each
time
an exposure is made,
thus
eliminating
the trouble
of
manually advancing
the
exposed
frame.
On the other hand, it affords
cont inuous automatic fi lm drive for rapid se-
quence
~;lotS.
The
foremost advantage of the
motor
drive unit
co
nsists
of
the
fact
that it permits
rapid
sequence
shooting
through
co
ntinuous
automatic film
d
ri
ve.
This
mode of operation
is
highly
effect ive
in
var ious
fields
of photography,
such as sports, scientific, educational and genera
l
photography, as well as wildlife
photography
Needless
to say, the single frame film
drive
mode is
equa
ll
y advantageous to the photographer
because
he
ca
n
co
ncentrate
sole ly on the photographic
subject and picture
compos
ition,
wit
hout
bother-
ing about film wind.
The use
of the motor drive
unit
with
the
CONTAX
RTS
offers
countless
advantages
that
ca
nnot
be otherwise expected.
In
the
first place, its use does not in the least
restrict
the original versatility of
the
camera
as
well
as
its fully
automatic
through
-t
he-Ien
s
ex-
posure
co
ntrol.
Then,
of course,
th
e
photo-
grapher
ca
n
take full advantage of the
orig
inal
maneuverab il ity and instantaneous
response charac-
teristi
cs
of the
camera
system.
For
utmost
convenience
and versatility, the use
o
f
the
Rea
l
Time
Wi
nder
is
recommended.
It is a
compac
t,
lightweight unit which
ca
n
be regarded
as standard equipment of the CONT AX RTS.
