Contax RTS Bedienungsanleitung
The CONTAX RTS is a, highly advanced electronic SIR system camera developed
by mutual cooperation of Carl Zeiss, West Germany, and Yashica, Japan. It
offers the advantage of the most sophisticated fully automatic through-the-lens
exposure control. Designed under the theme of "Real Time" * functional 1
response and disposition of information, it provides such capability in
al I fields of photography as could not possibility be expected of other
35mm SLR models. The New Bayonet Mount also a product of mutual cooperation
between Carl Zeiss and Yashica - affords perfect coordination of the optical,
mechanical and electronic systems. The exclusive 'Real Time' features are:
1. 'Real Time' LED Shutter Speed Display
By pressing the LED display button before or after film wind, the LED (light
emitting diode) in the viewfinder will come on instantly to display the
calibrated or in-between shutter speed ensuring correct exposure in relation
with the preselected aperture.
 |
2. 'Real Time' Magnetic
Release
Because this magnetic release trips the shutter through feather-touch
fingertip action, camera shake at the critical moment of exposure
is effectively prevented. Since, moreover, shutter tripping is accomplished
through contact of an electric switch, all types of off-hand controls
can be used directly. Correct exposure is obtained through 'Real
Time' light reading immediately before exposure. |
3. "Real Time' 1/2000 sec. Maximum Shutter Speed
Because your CONTAX RTS features an electronic focal plane shutter with
a unique design under which the primary and secondary curtains uncap to
provide starting from the same position, precise shutter speeds can be obtained
up to the maximum of 1/2000 sec.
4. '
Real Time' Oft-Hand Controls
Because the magnetic release functions strictly on electrical principle,
various types of electrically operated off-hand controls can be used directly
by merely plugging into the camera's release socket. The off-hand controls
currently available include the Infrared Controller Set and Interval Timer.
5. '
Real Time' Motor Drive System
The magnetic release does greatly more than just tripping the shutter. In
the final stage of its function, it switches on the motor drive switch to
provide -precise synchronization with the motor drive unit. Of the two types
of motor drive units, the Real Time Winder is a compact unit which can be
regarded as standard equipment of your CONTAX RTS.
6. '
Real Time' T* (T-Star) Carl Zeiss Lenses
-The high performance and extra-high speed design of the Carl Zeiss lenses,
featuring the T* (T-Star) multi-layer anti-reflection coating which minimizes
harmful glass-to-air reflections and assures 'Real Time color reproduction
and contrast permit the photographer to select comparatively high shutter
speed even in subdued light situations, thus offering new possibilities
in 'Real Time' photography.
|
The CONTAX RTS is designed to deliver superb photographic results
when mounted with any one of the Carl Zeiss or YASHICA lenses
with Contax/Yashica mount. The manufacturer will not be held
responsible for pictures of substandard quality when the same
camera is used in combination with lenses other than those specified
above. |
* 'Real Time' is a computer terminology denoting absence of physical time-lag

BASIC PROCEDURES OF OPERATION
The CONTAX RTS is designed to offer utmost ease
and versatility of operation in all fields of photography. As long as the
shutter control dial is kept at the 'AUTO' setting, fully automatic exposure
is assured under all light conditions, merely through pre-selection of the
lens aperture.
Read the following pages carefully and acquaint
yourself with the basic procedure of operation before attempting to take
your first series of photographs.
MOUNTING AND INTERCHANGING THE LENS
|
After removing the body cap and the lens rear cap, set the lens
properly in the mount by matching the red dot on the lens barrel
with that on the camera body. Then, give the lens a right turn
until it click stops into place.
To prevent hitches in focusing and exposure
control, always make sure the lens is locked properly in its mount.
Lens Interchanging
To remove the lens from its mount, twist it to the left while keeping
the lens release button depressed.
Before removing, make it a rule to place
the lens cap over the lens to prevent inadvertent scratching or
smearing of the lens surface. After removing the lens from its mount,
cover the rear end with the lens rear cap.
· Avoid direct sunlight when interchanging
lenses, particularly in case the camera is loaded with film.
· Set the body cap in the lens mount
in case the camera is to be left without it's lens.
|
 |
 |
CAUTION
The shutter system and the exposure control
of your CONTAX RTS will not function unless the battery is properly
installed.
Always use a 6V silver oxide or alkaline battery (Eveready 544,
Ucar 544, Mallory PX28, Alkaline Eveready 537 or equivalent).
1. Open the battery compartment cover by turning it with the edge
of a coin.
2. Install the battery with its minus (-)
end facing inside, and close the battery compartment cover.
|
|
When the battery power declines below the required voltage level,
the shutter will fail to operate. Therefore, make it a rule
to check the battery power (1 ) occasionally before shooting
and (2) after replacing the battery.
To check the battery power, press the battery
checker button. If the LED battery checker display comes on, sufficient
power is indicated. In the event if fails to come on, replace the
battery.
· When the battery power drains to
a low level, the LED battery checker display may come on momentarily
when the battery checker button is depressed. In such a case, replace
the battery.
|
 |
FILM LOADING
 |
Avoid direct sunlight when loading the film.
1. After sliding up the rubber eye-cup,
open the back cover by pulling out the film rewind knob. As soon
as the back cover is opened, the exposure counter will reset to
'S' (start position).
2. Place the film cassette in the film cassette
chamber and push the film rewind knob back to its original position.
· Use a standard 35mm cassette film
of 12, 20 or 36 exposure load.
|
 |
3. Clip the film tip on the take-up spool
as illustrated.
· Avoid inserting the film tip farther
than is necessary.
|
4. After making sure that the
shutter control dial is set at a position other than the 'AUTO'
setting, advance the film until the sprocket teeth properly catch
the perforations along both edges of the film. Then, close and press
the back cover until it locks into place.
5. Fold out the film rewind crank-handle and turn it in the direction
of the arrow to take up the film slack. |
 |
 |
* When folded, the crank-handle will rotate freely; therefore,
make sure it is returned into the compartment above the 'AUTO'
setting.
6. Press the magnetic release and advance
the film, alternately, until the exposure counter registers the
figured'
If the white line on the film rewind knob
rotates when the film advance lever is manipulated, it means the
film is advancing properly.
CAUTION
Avoid keeping the LED display pushbutton depressed when advancing
the film. Particularly in case the Real Time Winder is in use, make
it a rule to keep your finger off the LED display pushbutton when
making exposure.
|
 |
SETTING FILM SPEED
|
After the film has been loaded properly, set the film speed
dial according to the speed rating of the film in use.
To set the film speed, lift and turn the
collar around the film speed dial and align the index with the figure
corresponding to the ASA or DIN rating of the film in use.
· Always see to it that the index
is set properly in the click stop position. If set improperly, the
accuracy of the exposure control will be affected.
ASA/DIN Film Speed Rating
The ASA or DIN film speed rating specified on the outer box or in
the instruction sheet which comes with the film indicates the degree
of light sensitivity of the film emulsion.
|
 |
 |
The film can be advanced by one frame by giving the film advance
lever one sweeping stroke or several short strokes. In either
case, make sure that the lever is manipulated until it fails
to move any further.
Manipulation of the film advance I ever
to advance the film automatically registers count of exposure on
the exposure counter.
· The magnetic release will fail
to function if the film wind is incomplete. In case it fails to
operate, manipulate the film advance I ever once again to complete
the film wind.
How to check the film advance.
If, in the course of film winding, the white line on the film
rewind knob rotates accordingly, it is an indication that the film
is advancing properly.
|
The viewfinder of your CONTAX RTS shows the field
covered by the lens in use always at the maximum aperture. In addition to
the bright field, it provides preview of all necessary information for obtaining
correct exposure.
Microprism focusing spot
The standard viewing screen features a microprism center focusing spot which
affords precise focusing most readily. For details on how to secure focus,
refer to the pertinent section.
Aperture display
The figures along the top edge of the finder frame denote the f-stops. The
complete scale consists of 1.2, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22 and 32
settings. When the lens is mounted properly, the scale shifts to the right
or left, correspondingly, to display the maximum aperture of the lens in
use always on the extreme right.
When the aperture ring of the lens is turned, the
green pointer moves to display the preset aperture in green figure.
Shutter speed display
When the LED display pushbutton is depressed before or after film wind,
the LED dot comes on to display the shutter speed ensuring correct exposure
in relation with the preselected aperture. If the LED dot comes on within
the range of 2000 (1/2000 sec.) and LT (4 sec.), correct exposure can be
obtained as long as the shutter speed dial is set at the 'AUTO' setting.
If the LED dot comes on in alignment with 'A' or
'B', incorrect exposure is indicated; therefore, the lens aperture and/or
shutter speed setting must be readjusted accordingly.
When the green pointer overlaps the 'A' setting,
it means that the camera is set for fully automatic exposure. In case the
shutter control dial is adjusted to any position other than the 'AUTO' setting,
the green pointer will overlap the figure corresponding to the shutter control
dial setting.
Exposure compensation tab
When the film speed dial is turned and the exposure compensation
pointer is aligned with any setting other than 'X1', this tab appears on
the lower edge of the finder frame to signal that exposure compensation
is being made.
FOCUSING
 |
To secure focus, turn the focusing ring
of the lens while sighting through the viewfinder until the main
subject appears clearly defined. The microprism focusing spot at
the center of the finder field affords utmost convenience and ease
in focusing. Precise focus is secured when the multiple glitter
disappears and the image of the subject within the focusing spot
appears sharp and clear.
· The viewfinder of your CONTAX RTS
affords viewing and focusing always at maximum aperture. To check
the depth of field after securing precise focus, simply push in
the depth-of-field preview button.
The method of focusing remains the same
regardless of what type of lens or combination of the Auto Extension
Tubes is used.
· When necessary, the standard screen
featuring the microprism focusing spot can be interchanged with
any one of the four types of focusing screens available as optional
accessories
|
 |
SHOOTING POSTURE
|
Otherwise perfect shots are often spoiled by erratic movement
of the camera at the critical moment of exposure.
Make it a rule to support the camera firmly
with your left hand and, while gently gripping the camera body with
your right hand, press the magnetic release with the ball of your
right index finger. Also, see that you are fully acquainted with
the proper procedure of operation of your camera.
· Depending on how you wish to compose
your picture, you can hold your camera in either horizontal (top
photo) or vertical (bottom photo) posture.
· When required, steady your camera
by holding it against a wall or tree.
When a telephoto lens is use or when shooting
at a slow shutter speed, the use of a tripod to support your camera
is recommended.
|
 |
AUTOMATIC EXPOSURE
|
Your CONTAX RTS features fully automatic through-the-lens electronic
exposure control.
By simply presetting the film speed and
lens aperture, its highly sophisticated electronic circuit functions
to vary the shutter speed continuously and automatically according
to the subject brightness, thus ensuring correct exposure under
any light condition.
Besides fully automatic exposure control
through aperture preselection, your CONTAX RTS provides semi-automatic
exposure control through pre-selection of the shutter speed.
Automatic exposure through aperture preselection
1. Turn the shutter control dial
and align the 'AUTO' setting with the index on the camera top.
When thus adjusted, the green shutter speed
pointer in the viewfinder will overlap the 'A' setting.
· Make sure the exposure compensation
pointer is aligned with 'X1 '.
|
 |
 |
 |
2. Preselect the lens aperture. Turn the aperture
ring on the lens barrel and align the required f-number with
the index. The preselected aperture will be displayed in the
viewfinder in green figure. Refer to the table for approximate
aperture setting under different light conditions.

3. Press tag LED display pushbutton while sighting through
the viewfinder.
Depression of this pushbutton provides a
check of exposure condition before or after film wind.
If the LED dot comes on within the range
of 2000 (1/2000 sec.) and LT (4 sec.), it indicates that correct
exposure will be obtained at the preselected aperture.
In case two LED dots appear, it is an indication
that an in-between shutter speed will be set automatically.
|
|
|
|
|
| · One LED dot indicates
automatic setting of the shutter speed corresponding to the figure
in alignment. |
Two LED dots indicate automatic
setting of the shutter speed between the settings in alignment. |
 |
4. Advance the film and press the magnetic release.
If the LED dot displays a shutter speed
of 1/30 sec. or longer exposure, hold the camera steady to prevent
erratic movement at the moment of exposure.
· When the magnetic release is depressed,
the LED dot will come on momentarily to display the shutter speed
at which exposure is being made.
· Correct exposure can be obtained
through various combination of the lens aperture and shutter speed.
Depending on the subject condition, therefore, alter the aperture
setting to provide exposure at the right shutter speed.
· For best results, shoot your subject
with the sun behind your shoulder
|
16 DOT LED SHUTTER SPEED DISPLAY
The shutter speed display incorporated in the viewfinder of the CONTAX RTS
consists of a 16-dot LED (light emitting diode) array. The LED dot comes
on immediately upon depression of the LED display pushbutton to display
the shutter speed set in relation with the preselected lens aperture. This
shutter speed display is unique in the fact that it can be turned on regardless
of whether the film has been advanced or not. As explained in the foregoing
pages, one LED dot indicates automatic setting of the shutter speed corresponding
to the figure in alignment, while two LED dots signify in-between speed.
Under fluorescent light, more than two LED dots may sometimes come on at
the same time. Although it is not perceptible to the human eye, there is
a rapid fluctuation of the light intensity emitted by a fluorescent lamp
and, because of the extremely high speed of response of the light sensor
and the display, this variation of the light intensity is picked up, thus
resulting in flickering of the LED dots which appears to our eyes as simultaneous
lighting of three or more dots. This phenomenon
does not, however, signify a malfunction. When the shutter
is released, correct exposure will be made at the optimum shutter speed.
 |
1. When the LED dot comes on
in alignment with a figure below '30', correct exposure will be
obtained, but utmost precaution must be taken to prevent camera
shake. To prevent erratic movement of your camera at the critical
moment of exposure, (1 ) reset the aperture ring to a wider lens
opening in order to provide automatic setting of a higher shutter
speed, or (2) mount the camera on a tripod. |
 |
2. When the LED dot comes on
in alignment with 'A', stop down the lens aperture so that the LED
dot aligns with 2000 (1/2000 sec.) or smaller figure. |
 |
3. When the LED dot comes on
in alignment with 'B' set the aperture ring to a wider lens opening.
If the LED dot fails to move upward even at maximum aperture, resort
to flash exposure. |
Semi-automatic exposure through preselection of the shutter speed
 |
(Keep the shutter control dial at the 'AUTO'
setting and the exposure compensation pointer aligned with 'X 1'.)
1. Press the LED display pushbutton and
check the shutter speed.
2. While keeping the pushbutton depressed,
turn the aperture ring until the LED dot aligns with the figure
corresponding to the desired shutter speed.
The following table gives you a guide for
preselection of the shutter speed:
Fast-moving subjects
Landscape or general outdoor
photography
Indoor or night photography |
1/2000, 1/1000, 1/500 sec
1/250, 1/125 or 1/60 sec.
1/30 sec. or slower speed |
· When shooting sport scenes or moving
automobile, set the shutter speed at 1/500 sec. or higher speed.
The foregoing shutter speed preselection guide is based on using
ASA 100 film.
|
 |
FILM UNLOADING
 |
Make sure the exposed
film is rewound into its cassette before unloading it.
1. When the exposure counter registers the
figure equivalent to the exposure load of the film, avoid advancing
the film any further. If forced, the film may tear away, making
it impossible to rewind it into its cassette.
2. Give the film rewind release button on
the camera base a push. This button will reset automatically when
the film advance lever is manipulated; therefore, it is unnecessary
to keep it depressed with your fingertip during film rewinding operation.
3. Fold out the film rewind crank-handle
and turn it in the direction of the arrow. As soon as the crank-handle
is rotated, you will hear an audible signal indicating that the
take-up spool is turning in reverse and the film is being properly
rewound into its cassette. When the film pulls away from the take-up
spool, the audible signal will cease and you will feel an increased
resistance; however, continue winding until the crank-handle rotates
freely without resistance. Then, open the back cover
and take out the film cassette.
· If the film fails to advance part
way before the entire length has been exposed, do not attempt to
wind it forcefully. Instead, push the film rewind release button
and rewind the film into its cassette.

FEATURE OUTLINE
Magnetic Release
Your CONTAX RTS features a magnetic release of a unique design which opens
new horizons in system application.
Unlike the mechanical shutter release featured on other SLR models, this
magnetic release trips the shutter instantaneously with minimal stroke and
feather-touch fingertip pressure, thus preventing camera shake. It also
permits direct use of various off-hand controls. Its principal advantages
can be summarized as follows:
1. It affords instantaneous tripping of
the shutter.
The magnetic release system of your CONTAX RTS does not use a mechanical
plunger with long operating stroke. Instead, it functions strictly on electrical
principle and therefore trips the shutter instantaneously. When you press
the magnetic release, you are in effect switching on the magnetic release
circuit.
2. It permits direct use of various off-hand
controls.
Because the magnetic release system works on electrical principle, it affords
most convenient use of various off-hand controls, such as cable switches,
infrared controller set and interval timer. Moreover, it provides precise
synchronization of the shutter and motor drive operation, thus affording
use of the motor drive unit at all shutter speeds range on Auto.
3. It ensures Real Time light reading.
The magnetic release system does not feature any provision for standby switching
of the automatic through-the-lens light reading system. Simultaneously with
the activation of the magnetic release system, the electric current flows
to the electronic exposure control and Real Time light reading is taken
immediately prior to mirror flip-up.
Electronic Exposure Control The electronic exposure
control of your CONTAX RTS is based on through-the-lens light reading at
full aperture. For light reading, an SPD (silicon photo diode) is used.
This sensor responds to variation of light intensity at a speed several
thousand times faster than the CdS cell used m most SLRs and shows high
sensitivity in extremely low light levels. .
Light reading range
Your CONTAX RTS provides an extremely wide light reading range from EV -1
to 19 (F1.4 at ASA 100). EV (exposure value) denotes the value of exposure
through combination of the shutter speed and lens aperture; the actual exposure
to light of the film emulsion depends upon the speed rating of the film
and the intensity of the transmitted light. For instance, if correct exposure
can be obtained at EV 10 with ASA 100 film, the shutter speed must be adjusted
one setting toward a slower speed or the lens aperture must be opened by
one stop when using an ASA 50 film; therefore, the exposure valueatASA50will
beEV9ifthelight condition remains the same and, at ASA 20.0, it will be
EV 11.
MANUAL OPERATION
 |
On Auto, the shutter speed is set automatically according to
the subject brightness and on the basis of the preselected lens
aperture. It varies continuously and, therefore, provides precise
exposure even at in-between speed. On manual operation, however,
the shutter will not function at in-between speed settings.
Switch to manual operation in the
following instances:
· When photographing by preselecting
a precise shutter speed.
· In flash photography.
· In B (bulb) photography.
1. Turn the shutter control dial away from
the 'AUTO' setting. The green shutter speed pointer will then move
away from the 'A' setting in the viewfinder.
2. Set the required shutter speed setting in alignment with the
index. When thus adjusted the green pointer will overlap the corresponding
setting of the shutter speed scale visible in the viewfinder.
3. Press the LED display pushbutton and
check the position of the LED dot.
4. Turn the aperture ring until the LED
dot aligns with the preset shutter speed indicated by the green
pointer.
|
 |
 |
5. When the LED dot is properly aligned with the green pointer,
press the magnetic release to trip the shutter.
· On manual operation, the correct
exposure can also be obtained through preseleclion of the lens aperture.
In this case, preset the f-stop and then press the LED display pushbutton.
While observing the position of the LED dot, turn the shutter control
dial until the green pointer aligns with the dot.
· In case two LED dots come on simultaneously,
turn the aperture ring until a single dot aligns with the green
pointer.
· The 'B' setting is used for extremely
long exposure. When the shutter control dial is set at 'B', the
green pointer in the viewfinder will also overlap the 'B' setting.
When thus adjusted, the shutter will remain
open over the duration the magnetic release is kept depressed.
To avoid camera shake when making exposure,
mount the camera on a tripod or set it on a firm, plane surface
and tri p the shutter by using a cable switch. Make sure the switch
is pushed in properly. Lack of pressure on the switch may cause
the shutter to close before the required exposure is given.
|
EXPOSURE COMPENSATION
 |
When shooting backlit or spot-lit subjects or when special effects
are desired, turn the film speed dial and make exposure compensation
by aligning the pointer with the required setting on the exposure
compensation scale.
The exposure compensation scale has four
click stop settings besides the X1 setting for normal exposure,
namely, 4, 2, 1/2 and 1/4. The pointer can also be set at an in-between
setting.
To make exposure compensation, turn the
film speed dial and align the exposure compensation pointer with
the required setting on the scale. When thus adjusted to a position
other than the X1 setting, the exposure compensation tab will appear
in the viewfinder to signal that exposure compensation is being
made.
|
 |
 |
·
For backlit subjects, set the pointer at '2' or '4'.
When shooting against light or when photographing
subjects against a background of a bright window or snow scene,
your main subject will appear under-exposed if exposure is made
in the normal manner. To bring out fine details of your main subject,
align the exposure compensation pointer with the '2' or '4' setting
on the scale.
· For spotlight subjects, set the pointer at '%'
or "Gil'.
To prevent over-exposure of the main subject,
align the exposure compensation pointer with the 'I' or '9~' setting
on the scale.
· Make it ar Gletore set the exposure
compensation pointer to the 'X1' setting.
· On manual operation, it is advisable
to make the exposure compensation first and then adjust the exposure
by aligning the LED dot with the green shutter speed pointer.
|
 |
SELF-TIMER
 |
When you wish to
include yourself in the picture or in case the shutter has to be
tripped at a delayed action, use the self-timer.
1. Secure focus and advance the film.
2. Set the self-timer by pushing the self-timer lever all the
way in the direction of the arrow.
3. To activate the self-timer, push the self-timer start lover
in the direction of the arrow. The self-timer will then trip the
shutter at a delayed action of approximately 7 to 10 seconds.
· When using the self-timer to trip the shutter, slide
the rubber eye-cup mount upward as illustrated to prevent light
from entering through the viewfinder eyepiece. By thus shielding
the viewfinder eyepiece, exposure inaccuracy due to light filtering
in from the eyepiece can be prevented effectively.
· In case the film wind is incomplete, the self-timer
will activate when the self-timer start lever is pushed in the direction
of the arrow but it will not trip the shutter. In such a case, give
the film advance a complete wind and reset the self-timer lever.
· In case you decide not to use the self-timer after setting
the lever in the direction of the arrow, simply return the lever
to its original position.
· The shutter can be released in the normal manner by
pressing the magnetic release even when the self-timer lever is
set at the charged position.

DEPTH-OF-FIELD PREVIEW BUTTON/MIRROR LOCK
Depth-of-Field
Preview Button
Although the viewfinder of your CONTAX RTS
always provides viewing at all aperture, depression of this button
stops down the lens to the preselected aperture, thus enabling depth-of-field
preview.
Avoid tripping the shutter while depressing
the depth-of-field preview button because it will cause exposure
inaccuracy.
Mirror Lock
In photomicrography and extreme close-up
photography, better results can be obtained by making exposure with
the deflection mirror locked in flip-up position.
To lock the mirror, turn the mirror lock
lever to the right until the white line is set horizontal to the
camera base. Then, push in the depth-of field preview button. The
button will be locked in pushed-in state and the diaphragm will
close down to the preselected aperture.
Before locking the mirror in flip-up position,
compose, focus and make exposure adjustment.
After making the exposure, reset the mirror
to its original viewing position. As soon as the mirror resets to
its viewing position, the depth-of-field preview button will return
to its original position. The mirror lock lever can be operated
before or after film wind.
The automatic exposure control
will not work when the mirror is locked in flip-up position.

FLASH EXPOSURE
 |
When making exposure with the aid of an electronic flash unit,
turn the shutter control dial off the 'AUTO' setting and adjust
it to 1/60sec. or slower speed setting.
Your CONTAX RTS features an X sync terminal.
1. Mount the electronic flash unit on the
accessory shoe.
2. Connect the PC cord of the unit to the
camera's sync terminal. With a unit featuring direct contact shoe,
this step is unnecessary.
· The camera's direct contact shoe
has anti-shock provision. Circuit contact is made only when the
flash unit is properly mounted on the accessory shoe.
3. Adjust the shutter control dial to a
setting providing perfect flash synchronization. (Refer to the following
table for proper shutter speed setting.)

4. Secure focus, set the lens aperture and trip the shutter.
After securing focus, read the subject distance off the distance
scale and set the lens aperture according to the flash-to-subject
distance (See following page for details).
· The basic procedure remains the same whether you use
an electronic flash unit or a flash gun.

Correct Exposure Setting in Flash Exposure
Correct exposure in flash photography is determined
on the basis of the guide number of the electronic flash unit
or flashbulb in use. To obtain the aperture setting ensuring
correct exposure, divide the guide number of the electronic
flash unit or flashbulb in use by the flash-to-subject distance
(in feet or meters).
(Guide Number Flash-to-Subject Distance = Correct Aperture)
When the guide number is given in meters, convert the flash-to
subject distance into meters and then divide.
Example with GN 20 electronic flash
unit
When shooting a subject at a distance of 5meters by using an ASA
100 film and an electronic flash unit with a guide number of 20(ASA
100 in meters), the correct aperture will be:
20 (GN) DIVIDED BY 5 (Distance in meters) = 4 (F4)

INTERCHANGING THE CAMERA BACK/INFRARED PHOTOGRAPHY
Interchanging the Camera
Back
The camera back of your CONTAX RTS can be interchanged
with the Data Back or 250 Film Back available as optional accessory.
Remove the camera back as illustrated while pushing down the back
cover release lug. |

|
Infrared Ray Photography
In case of infrared
ray photography, focus compensation must be made after securing
focus in the normal manner by sighting your subject through
the viewfinder, For focus compensation in infrared ray photography,
use the R index on the lens barrel. After focusing in the normal
manner, turn the focusing ring and align the subject distance
with this R index.
· In case of infrared ray photography,
always use a red filter.
|
 |
· For proper exposure setting, read the instruction sheet which
comes with the infrared ray film carefully.
INTENTIONAL MULTIPLE EXPOSURES
The photographic technique under which exposure
of the same or different subject is made more than once on the same
frame is called intentional multiple exposure.
1. Trip the shutter and make the first exposure.
2. Give the film advance lever a full wind
while keeping the film rewind release button depressed. By doing
so, the shutter will be charged without advancing the film.
3. Press the magnetic release and make the
second exposure. Repeat the same procedure if exposure is to be
made more than twice on the same frame. Because, each time the film
advance lever is given a full wind, the exposure counter will advance
by one setting, keep track of the number of exposures made on the
same frame.
For intentional multiple exposure, it is
advisable to choose a dark background first and to superimpose a
subject with a brighter background. Multiple exposure of subjects
against an equally bright background will not come out too well.

INTERCHANGING THE FOCUSING SCREEN
 |
Before interchanging the focusing screen,
read the instructions supplied with each screen. Avoid touching
the screen surface directly with your fingertip. Use a pair of tweezers.
Also, take care not to touch the surface of the deflection mirror,
1. After removing the lens from its mount,
pull the focusing screen release lug forward (see illustration).
By doing so, the focusing screen frame will come loose, enabling
you to remove the screen with the aid of a pair of tweezers.
2. By using a pair of tweezers, catch hold
of the lobe on one edge of the focusing screen to be used instead
of the standard screen, and place it right side up in the screen
frame. Then, gently push up the frame until it locks into position.
CAUTION
Do not wipe the screen surface with cloth or tissue paper. In case
dust, grit or lint has accumulated in the viewfinder, blow it away
by using a blower brush, after removing the screen.

DEPTH OF FIELD
 |
When the camera lens is focused on a certain objects in the
foreground and background will appear acceptably sharp in the
picture. The range over which the foreground and background
objects are reproduced acceptably sharp is called the depth
of field. The photos on this page were taken with the lens focused
of the subject at the identical distance. At F1.4, objects in
the foreground and background appear blurred but, at F16, they
are reproduced sharp and clear. These photos illustrate that
the depth of field increases as you stop down the lens.
· The depth of field can be determined
either visually by pushing in the depth-of-field preview button
or by reading off the depth-of-field scale on the lens barrel. When
using the scale, secure focus and read off the range indicated by
the identical figures on both sides of the index corresponding to
the f-stop in use.
· The depth of field is more extensive
(1 ) as you stop down the lens, (2) as you focus on a more distant
subject, and (3) in the background rather than in the foreground.

PRECAUTIONS
· Do not leave your camera in the trunk or g love compartment of your car
or expose it to excessive heat. The battery as well as the camera mechanism
may become adversely affected by the heat, sometimes making it impossible
to obtain correct exposure.
When exposed accidentally to excessive heat, leave
the camera to cool to normal ambient temperature.
· The most common causes of malfunction are
exposure to humidity, salty sea breeze and subjecting the camera to knocks
and jolts. To obtain faithful service, take good care of your camera and
avoid rough handling.
· To clean the surfaces of the focusing screen,
deflection mirror and lens, always use a blower brush. Do not touch these
surfaces directly with your fingers. To wipe off smears on the mirror and
lens surface, use a soft, lintless cloth. Take utmost precautions when cleaning
the viewing screen surface.
· Keep the shutter in released state when
your camera is not in use. lit possible, take out the battery from the battery
compartment.
· Do not subject your camera to sudden changes
in temperature. It may cause the electrical contacts to corrode and may
bring about poor electrical contact.
· When installing the battery, make it a
rule to wipe both ends clean. Oily smears on the contact surface may cause
poor electrical contact.
· When the camera is to be left unused for
any great length of time, take out the battery from its compartment.
· When going out on long tours, make it a
rule to car spare battery.
· To prevent hazards, do not under any circumstances
throw used batteries into an open fire.
Your CONTAX RTS is designed to function normally
ambient temperature or +45 degrees to -10degre Because of the temperature
characteristics of the battery in use, the battery checker display may fail
to come c extremely low temperature. In such a case, replace battery with
a new one.
Batteries which fail to work in low temperature
will cover sufficient power when left for some time in normal ambient temperature.
For best results in extremely low temperature, the
use an alkaline battery is recommended.
