Lens Changing
<Mounting the Lens>
First remove the camera-body cap and then insert the
lens mount into the camera-body mount, matching the
red dot on the lens mount with that on the camera
body. Then, gripping the lens barrel firmly, turn the
lens clockwise until it locks with a click. When
mounted correctly, the aperture/distance scale index
on the lens will point toward the top of the camera.
When using a lens cap of the snap on type, attach or
remove it from the lens by pressing in the two side-
tabs.
<Removing the Lens>
While pressing the lens release button, turn the lens
counterclockwise slightly and remove it from the
camera-body mount. Always keep caps on the camera-
body mount and the lens mount when the lens is left
off the camera.
Avoid touching camera interior or lens surface with
your fingers. Avoid direct sunlight when removing or
mounting the lens with film loaded in the camera.
Installing Batteries
Batteries power all the cameras functions
including shutter system, exposure control, etc.
The FX-70 Quartz will not operate without
batteries.
Use two 1.55 V silver-oxide batteries (SR44,
Eveready S76, Ucar S76, Mallory MS-76 or
equivalent) or 1.5 V alkaline-manganese batteries
(LR44 or equivalent).
1. Open the battery compartment cover on camera
base by turning it counterclockwise with a coin.View original page 5Page 6 · Read text
2. Insert two batteries into the battery holder according to polarity diagram shown on the holder. Then replace the holder in the battery compartment and firmly secure the compartment cover. If the battery polarities are inserted incorrectly, the camera will not operate. 3. Set the shutter selector to "AUTO" (or X, B), and while looking into the viewfinder, press the shutter release lightly to check that the viewfinder LEDs light steadily or flash. <Battery Check> Battery condition is indicated by the LED display inside the viewfinder. When batteries are good, the LEDS will light steadily, or flash at regular intervals. When batteries are weak, the camera will warn you of this condition by changing to the flashing LED display shown in the diagram shown below. The camera will continue to operate for a period in this condition, but you should replace the batteries with new ones as soon a possible. When battery power falls below rated voltage, the LEDs will not light, and the camera will not operate. The LED display will remain lit for about 10 seconds after you release your finger from the shutter release button. <Battery Precautions> * Battery life is approximately 1 year with silver-oxide batteries, and about 6 months with alkaline - manganese batteries, but this may vary depending on frequency of camera use, the strength of batteries at time of purchase, ambient temperature, etc.View original page 6

* Batteries are apt to perform poorly in sub-zero temperatures, causing picture taking difficulties and LED
failure. Keep the camera as warm as possible and carry extra batteries just in case those in the camera should
fail. Batteries affected by such extreme temperatures will recover power after being kept warm for a while.
* When installing batteries, wipe the cell cap and base clean. Oily residue on battery terminals could cause poor
electrical contact.
* Remove the batteries when the camera is not used for extended periods.
* Make it a rule to carry spare batteries with you on long trips.
* Do not throw batteries into a fire or attempt to take them apart.
THIS IS DANGEROUS. Also keep batteries out of reach of small children.
Film Loading
Always use a standard 35 mm film
cartridge (12, 20, 24 or 36 exposure roll).
Avoid direct sunlight when loading film.
1. Open the camera back by pulling the
film rewind knob all the way out.
2. Place the film cartridge in the film
chamber. Then, push the rewind knob
back in, turning it slightly until it falls
into position, if necessary.
3. Draw out the film leader and insert the
tip into any slot on the take-up spool.
(4) Advance the film slightly with the film
advance lever until the perforations on both
sides of the film engage the sprocket teeth. If
necessary, trip the shutter for blank shots and
keep advancing the film until both rows of
perforations engage the sprocket. Close the
camera back and Dress until it locks into place.View original page 7Page 8 · Read text
<Film Advance Lever> Use one full stroke of
the film advance lever to advance the film. The
electromagnetic shutter release will not function
unless the lever is given a full stroke. The film
advance lever is easier to I operate if it is kept in
the standoff position (20 degree arc)
5. Unfold the rewind crank and turn it gently in
the direction of the arrow to take up film slack.
(6) Wind the film advance lever and trip
the shutter alternately until the exposure
counter reads "1". Now you can start
taking pictures. If the film rewind knob
rotates in unison with the operation of the
film advance lever, it means that the film
is feeding properly.
When taking blank exposures, remove the
lens cap and point the camera toward a
bright area, or set the shutter selector "X"
or "B" and press the shutter release button.
If blank exposures are made with the lens
cap in place and the shutter selector set to
"AUTO", excessively long exposures will
result.View original page 8Page 9 · Read text
www.butkus.us
<Exposure Counter> The exposure counter moves each time the film advance lever is fully stroked, and
automatically resets to "S" (Start) when the camera back is opened, regardless of whether the camera is loaded
or not. The exposure counter starts with "S", then "1", followed by even numbers from "4" through "36". The
odd numbers are indicated by dots marked between the even numbers. The orange-colored numbers "12", "20",
"24" and "36" correspond to the number of exposures in standard 35 mm film cartridges.
Setting the film speed
Proper film speed setting is necessary to assure correct film
exposure. The film speed number (ASA/ISO) in normally
indicated on the film box.
While pressing the film-speed dial release-button, rotate the
film speed dial until the ASA/ISO film speed number for the
film being used lines up with the exposure compensation
index mark "X1" (orange-colored). Then, release the button
and check to see that the dial is set on the proper click stop.
Film Speed Values (ASA/ISO)View original page 9Page 10 · Read text
Shutter selector This shutter controls the amount of time the film is exposed to light. All shutter speeds on the FX-70 Quartz, including "AUTO" (automatic exposure), "B" (bulb), and "X" (Flash Sync-Speed), are controlled by an electronic circuit using a highly accurate quartz oscillating element. <Shutter Selector Modes> "OFF"..... In this position, the batteries are turned off and the camera does not operate. When not using the camera, set the shutter selector to this position to avoid unnecessary battery drain and accidental exposures. "AUTO".... In this position, the shutter speed is automatically controlled to give correct film exposure for the aperture setting selected, subject brightness, and speed of film being used. This setting is also used when making flash pictures with the electronic flash unit CS-201 Auto, (or the Contax TLA20, TLA30). "B" ...... (Bulb) In this position, the shutter remains open for as long as the shutter release button is depressed. "X"..... (Flash Sync-Speed) In this position, electronic flash units other than the CS-201 Auto (or Contax TLA20, TLA30) can be used for making flash exposures. The flash sync-speed is set at 1/100 second.View original page 10

Aperture Ring
The aperture ring regulates the amount of light
transmitted to the film plane. The amount of light
transmission is halved when the aperture is changed to
the next larger F value (for example, when f/4 is changed
to f/5.6), and doubled when it is changed to the next
smaller f value. The aperture also controls the depth of
field, a lens property giving you varying depth in the
plane of focus at different apertures. (Refer to page 76)
To set the aperture, turn the aperture ring until the desired
aperture setting is aligned with the aperture/distance scale
index. The aperture ring can be used at in-between
positions. With the exception of PC Distagon and mirror
lenses, all Yashica and Zeiss interchangeable lenses
feature automatic diaphragms that stop down the selected
aperture when the shutter is activated. Thus, your
viewfinder always gives you a bright image at full
aperture of the lens used.
Focusing
Focusing with the FX-70 Quartz is done by using any element of its
convenient Freeway focusing system consisting of a split image spot, a
microprism collar and an outer matte field.
<Horizontal Split image Spot>
When using the split-image spot to focus, turn the focusing ring until the top
and bottom halves of the image merge. If the image is out of focus, the two
halves will not merge.
<Microprism Collar/Matte Field>
To focus with the microprism collar, turn the focusing ring until the
glittering effect disappears from the collar area, giving you a sharp, clear
image when in focus. To focus with the outer matte field, turn the focusing
ring until the image appears sharp and clear, free of any foggy effect.View original page 11Page 12 · Read text
· When using long focal length lenses, or
lenses with a relatively small maximum
aperture 04 or slower), or when
performing close-up photography at high
magnification, the microprism collar and
split image spot may become dark,
making focusing difficult. In this case,
focus using the outer matte field.
<Diopter Lenses> Special correction
lenses are available for those who find it
difficult to focus with their eyeglasses on.
There are 8 types available: -5D
(diopters), -4D, -3D, -2D, OD, + 1 D, +
2D, and + 3D. Choose the one suited to
your eyesight needs. These lenses should
be used with an accessory eyecup.
Holding the camera
In order to take a beautiful, in-focus photograph, it
is necessary to hold the camera steadily. Since most
blurred pictures are caused by camera shake
(moving the camera at the instant of exposure), you
should practice with the camera until you feel
accustomed to holding it properly.
Hold the camera in the palm of your left hand,
using your fingers to rotate the focusing ring. Hold
the camera's handgrip firmly in your right hand,
resting your forefinger on the shutter release
button. With your left elbow against your body,
hold the camera up to your face firmly, and while
looking through the viewfinder, press the shutter
release lightly. Besides the horizontal position, the
camera can of course also be used to take pictures
in the vertical position. In any event, practice until
you find the positions that best suit your own
photographic style.
Depending on conditions, it may also be a good
idea to stabilize the camera by leaning your body
against a building, resting the camera on a fence or
other support, etc.View original page 12Page 13 · Read text
www.butkus.us Inside the viewfinder <LED Indicators> When the shutter release button is pressed lightly, the red LEDs (light emitting diodes) will light or flash to indicate the shutter speed at time of exposure. The LEDs will remain lit for about 10 seconds after you remove your finger from the shutter release button. <Flash-Ready Signal Mark> When using the flash unit "CS-201 Auto" or the Contax "TLA30", "TLA20" flash units, this signal mark will light green when the flash unit is recharged and ready to use. <Shutter Speed Scale> The numbers in black at the right of the viewfinder indicate the camera's shutter speeds in fractions of seconds (e.g. "1" = 1 second, "2" = 1/2 second, "125" = 1/125 second, ... "1000" = 1/1000 second). The red "2" means 2 seconds, and the "LT" means automatic "longtime" exposures up to 11 seconds. "B" indicates underexposure or use of the B (Bulb) shutter selector setting, and "OVER" indicates overexposure.View original page 13

Film rewind When all frames on a roll of film have been exposed, you will be unable to operate the film advance lever. Do not attempt to advance the film further, as tom film may result Check the exposure counter, and when it shows you have completed a roll of film, always be sure to rewind the film into its cassette before opening the camera back. After removing the film, have it processed as early as possible. 1. Press the film rewind release button on the base of the camera. Continuous pressing is unnecessary as the button is an automatically resetting type. 2. Unfold the film rewind crank and turn it in the direction of the arrow. Keep turning until you feel a light resistance shortly before the film comes off the take-up spool and continue turning until the crank eventually rotates freely. Light metering system The FX-70 Quartz features a TTL fall- aperture metering system that measures the light coming through the lens at the lens's fully open (largess aperture. The light meter is a "center-weighted" type, meaning that the meter primarily measures subject brightness at the center of the viewfinder, giving less emphasis to surrounding areas. The metering method is "aperture priority", meaning that once the film speed and lens aperture have been set, shutter speed is controlled automatically in response to subject brightness, to give correctly exposed photographs. The shutter speed at time of exposre is indicated by the LED display inside the viewfinder.View original page 14

www.butkus.us
<Built-ln Exposure Meter>
The shutter release button of the FX-70 Quartz also acts as the switch for the built-in exposure meter. When the
shutter release button is touched lightly, the switch is turned ON, and the LEDs inside the viewfinder light
steadily or flash to indicate the exposure at that time. After removing your finger from the shutter release
button, or after taking a picture, the exposure meter remains ON, turning itself OFF automatically 10 seconds
later.
If the shutter release button is pressed further, the shutter will be tripped.
Since this is a centenweighted type metering system, the center ring in the viewfinder should be placed on the
subject you wish to photograph in order to ensure correct exposure.
<LED Indicators during Automatic Exposure> When exposure is correctly metered, the LED beside the
shutter speed at that time will light steadily. If the ambient light conditions exceed the metering capabilities of
the camera, the "OVER" or "B" indicators will flash to indicate respectively over-exposure and underexposure.
· When a LED from "1000" through "LT" lights
up: Correct exposure has been metered and a picture
may be taken. The LED will light beside the correct
shutter speed for that time. If two LEDs light
simultaneously, the exposure will be made at a shutter
speed in between the two indicated values. If the LED
indicates a shutter speed of 1/30 second or slower,
handheld exposures may result in camera shake. In this
case, use a larger lens aperture, a flash unit, or mount
the camera on a tripod to steady it.View original page 15Page 16 · Read text
· When the "OVER" LED flashes: This indicates
that the subject is too bright, and overexposure of the
film will result. In this case, stop-down the lens
aperture until the indicated shutter speed is 1/1000
second or slower. If the LED continues to flash even
after the lens is closed to its minimum aperture, a
separately purchased ND (neutral density) filter should
be used on the lens to reduce the amount of light
transmitted.
· When the "B" LED flashes: This indicates that the
subject is too dark, and under exposure will result. In
this case, open the lens aperture until the indicated
shutter speed is "LT" or faster.
<Light Reading Range> The table gives the EV Light reading range for various lenses, showing the inter-
relationship between aperture, shutter speed and EV (exposure values). For instance, when an f/1.4 lens at
ASA/ISO 100 is used the reading range spanning the points that the vertical lines (EV) and the horizontal linesView original page 16Page 17 · Read text
www.butkus.us
(shutter speed) intersect with the diagonal lines extending from the f values of "1.4" to "16" (representing the
minimum aperture of the Yashica Lens ML 50 mm f/1.4), denotes the reading range from EV 1 to 18.
* The EV denotes the value of exposure through combination of the shutter speed and the lens aperture that
yield the same exposure effect on a film when the photographing conditions (film speed rating and prevailing
illumination) remain the same. For example, when using EV 13 from the chart as a guide, it can be seen that the
same exposure effect is attained using the combinations of f/16 at 1/30 sec. and f/8 at 1/125 sec.
* The table showing EV from 1 to 18 and shutter speeds from 11 to 1/1000 sec. denotes the range over which
the camera correctly meters the light in the AUTO mode.
* That part of the operating range which is shown in color denotes the light reading range when using an f/1.4
lens at ASA/ISO 100.
Automatic Exposure
The FX-70 Quartz gives correct
exposures automatically merely by
setting the lens to your desired aperture,
thus allowing you to photograph while
paying fall attention to your subject.
(1) Set the Shutter Selector to
"AUTO". This place the camera in the
automatic exposure mode, so that the
shutter speed is set automatically.
(2) Set the Aperture.
Turns the aperture ring on the lens to your desired f/stop.
Intermediate positions may also be used.
(3) Focusing and Composing. Point the camera at the
subject, and while looking through the viewfinder focus by
turning the focusing ring, and compose the picture.View original page 17Page 18 · Read text
(4) Check the Exposure and Shoot.
Press the shutter release button lightly and check the LED
indicators within the viewfinder. If any of the LEDs from
"1000" to "LT" light, the indicated shutter speed will give
you the correct exposure, and you may press the shutter
release button further to take the picture.
<Shooting at Your Selected Shutter Speed>
By applying the interrelation between aperture setting and
shutter speed (the larger the aperture, the faster the shutter
speed, and vice versa), your can vary the aperture setting in
order to photograph your subject at a particular shutter
speed when desired.
<Shooting Away from Viewfinder in Auto Mode>
Exposure metering can be affected by stray light entering
via the eyepiece when it is left unshielded during Auto
mode shooting using a self-timer or remote control
accessory. In this case, attach an accessory eyecup to the
viewfinder eyepiece as shown in the illustration, slide it up
and fold the rubber part so that it blocks out any stray light.
Exposure compensation
In automatic exposure photography, there may be cases
when correct exposure of the subject cannot be achieved
normally due to strong backlighting, or a large difference in
the amount of light falling on the subject and background.
In these cases, as well as when you wish to take deliberately
under or overexposed photographs for special effects,
exposure compensation is necessary. The FX-70 Quartz is
equipped with a one-touch AE lock lever, and an exposure
compensation scale, both of which allow you to perform
exposure compensation when required.
<Using the AE (Automatic Exposure) Lock Lever>
This device memorizes the exposure (shutter speed) at time
of exposure metering. When the AE lock lever is turned in
the direction of the handgrip, the shutter speed indicated at
that time will be memorized inside the camera, and the LED
beside that shutter speed in the viewfinder will begin
flashing. To expose the picture, press the shutter release
button while continuing to hold the AE Lock lever in
position. When the AE Lock lever is released, the
memorized shutter speed will be cleared, and the LED will
light steadily, automatically going out 10 seconds later.View original page 18Page 19 · Read text
www.butkus.us
<Examples Using the AE Lock>
As shown in the photograph on the
next page, when a strongly backlit
subject (bright light coming from
behind the subject) is photographed
without compensation, the subject
may appear very dark in relation to
the background. In this case,
approach the subject closely so that
the subject fills the entire field of
view in the viewfinder, and while
holding the AE lock lever toward
the handgrip, return to your
original positin and take the
picture. In this way the central
subject will be exposed with the
proper brightness. Using the AE
lock lever in this way allows you to
achieve good results simply, under
such difficult conditions as
backlighting, bright background
lighting, or when the subject is
illuminated by spotlight, etc.
<Using the Film Speed Dial>
For normal automatic photography, the numerical film
speed value (ASA/ISO number) of the film used is set
opposite the "X1" position on the exposure compensation
scale, but in order to perform exposure compensation,
depress the film-speed-dial release button, and turn the dial
until the speed value of the film in use lines up with the
desired compensation scale reading. The exposure
compensation scale can be used at intermediate settings and
can be click-stopped in 1/3 increments between scale
readings.
Always reset the ASA speed value for the film being used
to "X1" when exposure compensation is no longer needed.View original page 19Page 20 · Read text
· At some film speeds, exposure compensation settings cannot be used, as indicated in the table as follows (these settings exceed the camera's film speed range). Values "2" and "4" Increase the Amount of Exposure In situations such as shooting against the light or where your subject is back-lit by a bright sky or beach scene, or when you want to overexpose intentionally, set the dial at "2" or "4". The "2" setting corresponds to a change of one f-stop, and the "4" to two f-stops. Values "1/2" and "1/4" Decrease the Amount of Exposure In situations where the background is dark because of spotlighting of the subject or where you want to underexpose intentionally, set the dial to "1/2" or "1/4". The "1/2 " setting corresponds to a change of one f- stop, and the "1/4" to two f-stops. Flash Photography When shooting indoors or at night, the use of an electronic flash unit is recommended. For this purpose, the dedicated electronic flash "CS-201 Auto" can be used with the FX-70 Quartz. <Using the "CS-201 Auto"> When the FX-70 Quartz is used in combination with the CS-201 Auto flash unit, automatic flash photography can be performed with the shutter selector set to the "AUTO" position. Set the flash unit's selector to "AUTO". When the unit is fully charged, the camera will automatically switch to the flash synchro shutter speed of 1/100 second, and the flash ready signal " ~ " inside the viewfinder will light, showing that the camera and flash are ready to photograph. When the shutter release button is pressed lightly, the LED beside the "125" will flash.View original page 20
Page 22 · Read text
<Finder Display>
When combined with the CS-201 Auto flash, the camera's
flash ready signal " ", and the LED display function
will operate as shown right, regardless of the flash mode
(auto, manual). In addition to the CS-201 Auto flash, the
viewfinder display will be the same when the Contax
"TLA30" or "TLA20" flash units are used, but in this case,
TTL flash metering will not be performed.
<Using Other Flash Units>
The FX-70 Quartz is provided with an X-synch contact for
1/100 sec. shutter speed. Set the shutter speed selector to
"X". (The shutter speed LED opposite "125" will flash.)
* You can also take flash pictures with the selector set at "AUTO". In this case, make sure the shutter speed
indicator in the viewfinder shows 1/60 sec. or slower.
* When using other electronic flash or flash bulb unit, use one of the cordless type.
* With flash bulb units, use a shutter speed of 1/30 sec. or slower.
Quartz Self-Timer
The self-timer is used when taking group pictures or
on other occasions, when you wish to include yourself
in the photograph. When the shatter release button is
pressed, the self-timer LED flashes to let you know the
self-timer is operating.
(1) First, focus the camera, then turn the self-timer
lever in the direction of the arrow until it stops. The
self-timer is now set. The self-timer can be set either
before or after advancing the film.
(2) Check to make sure the film is
advanced, then press the shutter release
button. The self-timer LED will begin
flashing, and 10 seconds later, the
shutter will be automatically tripped.
During the last two seconds before the
shutter trips, the flashing of the self-
timer LED will become more rabid.
letting you know that the shutter is about
to be released.
During the operation of the self-timer,
you can cancel the self-timer by pushing
the lever back to its original position.View original page 22Page 23 · Read text
www.butkus.us After completing use of the self-timer, be sure to return the self-timer lever to its home position. If left in the set position, the self-timer will operate each time the shutter release button is pressed. * When using the self-timer for automatic exposures, use an eyecup to shield the viewfinder eyepiece from outside light (refer to p. 52) * During the operation of the self-timer, the LED indicators inside the viewfinder will go out. * The self-timer will not operate when the shutter selector is in the "B" position. "B" (Bulb) photography When making photographs of starts, or other photography at night requiring long exposure times (1 second or longer), set the shutter selector to "B" (Bulb). In this mode, the shutter will remain open, and the film will be exposed, for as long as the shutter release button is held depressed. In this case, camera shake is inevitable with hand-held photography, thus the camera should always be mounted on a tripod, or rested on a solid surface to keep.it immobile. To further remove any possibility of camera shake, the Cable Switch S (optional accessory) should be connected to the camera. Inside the viewfinder, the LED will flash at the "B" position, and when appropriate, another LED will light steadily beside the shutter speed appropriate for the aperture which has been set.View original page 23
