· The batteries packed with the camera are supplied as tester. It can be used only for testing all available camera functions.

Turning ON and OFF the Camera
The power switch of the camera is turned on and off by means of the Shutter Dial. If you set the Shutter Dial at any position other than "OFF", it will turn on the power switch of the camera. If you are not taking pictures, set the Shutter Dial at "OFF" to prevent the shutter from tripping accidentally and save the battery power.

Film Loading

Set the Shutter Control Dial to any position other than "OFF", open the Camera Back and load the film. Open the Camera Back by pushing down the Camera Back Lock while pressing in the button on it. To insert the film, first fit the recess of cassette to the shaft on the top of the film chamber and push in the film cassette smoothly.4www.butkus.org

· Always load and unload film in subdued light.
· Use DX-coded film. If non DX-coded film is used, the camera will set its film speed to ISO 100 automatically.

2. Insert the film leader under the orange mark
 "" -- "" and close the Camera Back.
Engage the film perforations with the teeth on sprocket and insert the leader of film in the slot under the orange mark "" -- "" at the end of the film channel. Make sure the film lies flat on the film channel as shown.

· If the leader of the film is too long, adjust its length by rewinding it back into the film cassette.

3. Slightly depress the Shutter Release and the film will automatically advance to the first frame. If you depress the Shutter Release, the film will automatically advance and the Exposure Counter will switch from "S" to "1". After the film has advanced, take up the film slack by erecting the Film Rewind Crank, follow the direction of arrow and turn it gently as far as it will go. Reset the Film Rewind Crank to the original position after taking up the film slack. The camera is ready to take pictures. If the Film Rewind Knob turns after you have depressed the Shutter Release, the film is advancing properly.

< Exposure Counter > 
The exposure counter advances every time the automatic winding mechanism operates, and returns to "S" (Start) when the camera back is opened, regardless of whether or not there is film in the camera. 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", "24" and "36" correspond to the number of exposures in standard 35mm film cartridges.4www.butkus.org

The Shutter Dial is used as the power switch of camera, it is also used for seeing auto exposure modes and shutter speeds in case of manual exposure. Turn and set the dial to your desired exposure position.

< Shutter Dial Setting >
"PROGRAM" - standard programmed auto exposure The camera will automatically select the correct combination of shutter speed and aperture from its program according to the brightness of the subject. "HP" High-speed Programmed auto exposure This mode will give a priority to a fast shutter speed for providing correct exposure. This mode is useful for shooting quick sports scenes or sharp portraits against a blurred background. It is also good for avoiding camera shake when taking pictures with a telephoto lens.

"AV" Aperture-priority auto exposure If you set your camera at the desired aperture, the camera will automatically control the shutter speed according to the brightness of the subject to provide correct exposure. This mode is suited for shooting with lens with depth-of-field emphasis. 

"2000,1000 - 2, 1"
"In the manual exposure mode, choose your desired shutter speed on this dial. "2000" means 1/2000 second, "1000" means 1/1000 second, , and "1" means 1 second.

"B" Bulb
As long as the Shutter Release is held depressed, the shutter will remain open to expose the film. 

"X" Flash synchronizing speed Set the Shutter Dial to "X" it pictures are taken with flash units other than dedicated flash (CS-140 FLASH or CS-220 AUTO FLASH). The synchro socket of the camera is a direct "X contact" type and the shutter will trip at 1/90 sec. "OFF" Camera OFF The power switch of the camera is turned off.

* Intermediate setting are not available on the Shutter Dial index. Do not set in-between positions.

< Drive Selector >

With the Drive Selector, you can set the film drive mode at either "S" (Single) or "C" (Continuous). Switch it to suit your purpose. "S" Each time the Shutter Release is depressed, the shutter trips to expose one frame, then the film will advance to the next frame, before it will stop.

"C" As long as the Shutter Release is held depressed, the shutter will trip in succession to take pictures one after another. If you take your finger off the Shutter Release, then the film will advance to the next frame, before it will stop.4www.butkus.org

Holding the Camera
To take sharp picture, it is important to hold the camera still. Because the main cause of blurred pictures is camera shake, it is recommended to learn how to hold the camera and find the best position that suits you. Place the camera in the palm of your left hand, hold the len's focusing ring so that you can turn it with your fingers; grip the camera with your right hand and put the forefinger lightly on the Shutter Release. Stick the left elbow to your body, press the camera lightly against your face and look through the viewfinder. Always depress the Shutter Release slowly and gently. To accommodate objects of different shapes, the camera can be used both in the horizontal and in the vertical position. In either case, choose the position that suits you best.  Sometimes you could gain stability and support by leaning against a building or tree when pictures are taken.

Display In the Viewfinder

If the Shutter Release is lightly depressed when the camera switch is on, the relevant display in the viewfinder will light up or blink for about 8 seconds showing the following shooting information's.


" " Lights up: When the Shutter Dial is set to an auto exposure mode ("HP", "PROGRAM ", or "AV").

" " Blink: When the control range of the program is narrow. The lens cannot be adjusted down to the "HP" or "PROGRAM" mode. In this case, adjust it to its minimum aperture (or the largest f-number).

"" Lights up: When the exposure is correct in the manual exposure mode.

""Blinks: When the Shutter Dial is set to "B" (Bulb).

"" or "" Lights up: In manual exposure, when the exposure is over " "" " or under "" within 1 EV relative to the correct exposure.

"" " or " "' Blinks: In manual exposure, when the exposure is over " " or under " " by more than 1 EV relative to the correct exposure. In aperture-priority auto exposure (AV), when the set aperture is not within the camera exposure control range.

"" Lights up: When it is fully charged on a dedicated flash (CS-140 FLASH or CS-220 AUTO FLASH).

" " Blinks: When the shutter speed is slower than 1/30 second in an auto exposure mode, this sign is to warn you of a risk of camera shake In this case, use a flash unit or support the camera with a tripod.


Focusing is done with the split image in the center of the viewfinder, the microprism collar around it, or the surrounding matte screen.

<Horizontal Split-lmage Spot> 4www.butkus.org
While looking through the viewfinder, turn the focusing ring until the upper and lower halves of the split image coincide. If the image is not in properly focused, the two halves do not coincide.


< Microprism Collar and Matter Screen > Turn the focusing ring until the image on the microprism or mane screen appears sharpest. If the subject is not in sharp focus, the image on the matte screen unsharp.

·If you are using a "slow" lens or taking close-up with a high magnification, you may not be able to focus properly. In such case, focus with the surrounding mane screen.

·If you are far-sighted or near-sighted, use an optional FL type diopter lens. There are eight types available, (-5, -4, -3, -2, O. +1, +2 and +3), which can be attached to the Viewfinder Eyepiece.

Rewinding the Film

After the entire roll of film has been exposed, the shutter will no longer trip. Sometimes the Reflex-mirror inside the body may stop halfway up. Make sure the end of the film is reached on the camera.

1. Press in the Film Rewind Button on the bottom of the camera.

· It is not necessary to hold the button down. 2. Turn off the battery power of the camera. Erect the Film Rewind Crank and turn it in the direction of the arrow to rewind the film.

Lights up - Underexposure within 1 EV.

Blinks Underexposure of more than 1 EV.

3.  Focus the lens and compose your picture Focus the lens by turning its focusing ring, compose your picture and shoot.

Bulb Exposure
To take night scenes or pictures of the sky at night requiring long exposure time, set the Shutter Dial at "B" (Bulb). Then, as long as the Shutter Release is depressed, the shutter remains open to allow long exposure time on the film. To avoid blurred pictures, mount the camera on a tripod or put it on a stable base and trip the shutter with a Cable Switch (optional accessory).

* When the Shutter Dial is set at "B" the lamp "" will blink in the viewfinder by depress)  the Shutter Release

Backlight Compensation Button
If you are shooting in an auto exposure mode ("HP", "PROGRAM", or "AV") and your subject is black-lighted or situates in front of a bright window, it will be underexposed and appears dark in the picture. In this case, trip the shutter while pressing in the Exposure Compensation Button. Your subject will be exposed with an exposure compensation of +1.5 EV.

If you want to include yourself in a group picture or a souvenir picture, use the self-timer. 1. Focus the lens on the subject and compose your picture. 2. Depress the Self-timer Button. The Self-timer LED will turn on and the shutter will automatically trip in about 10 seconds. The Self-timer LED will light up for the first 8 seconds, then will blink for the remaining 2 seconds to warn you right before tripped of the shutter.4www.butkus.org

· To stop the self-timer after it has been activated, simply press the Self-timer Button once again.

· If you depress the Shutter Release while the self-timer is running, the shutter will trip immediately.

· Under strong daylight, if you start the self-timer without putting your eye on the Viewfinder Eyepiece, it is advisable to cover the eyepiece with the Eyepiece Cover. However, you need not attach the Eyepiece Cover in manual mode.

Flash Photography
If the lamp "" blinks, the subject is dimly lighted. To avoid camera shake, it is recommended to use a dedicated flash. (The CS-140 FLASH and CS-220 AUTO FLASH are available as optical accessories).
  If you use any of these flash units, the lamp "" will light up in the viewfinder as soon as the flash is fully charged.

<Using a dedicated flash> 
Set the camera for aperture-priority auto exposure or manual exposure. Choose and set the aperture according to the instructions in your flash manual. In the aperture-priority auto exposure mode, as soon as the flash is fully charged, the shutter speed will automatically switch to 1/90 second. If you are shooting manual exposure mode and the shutter speed has been set to "2000" (1/2000) - "125" (1/125) see, it will switch automatically to 1/90 sec. If it has been set to "60" ( 1/60) sec. or slower, the shutter will trip at the speed that has been set.

<Using an ordinary flash> 
Select the manual exposure mode and set the Shutter Dial at "X" or "60" ( 1/60) sec. or slower. Choose the correct aperture setting according to the instruction in your flash manual

<Slow-shutter flash> 
If you choose a shutter speed slower than 1/60 sec. in the manual exposure mode. you can take pictures in a twilight or night scene with flash. Choose the correct aperture according to the instructions in your flash manual. While checking the marks " "***" " and " "***" " in the viewfinder, ad just correct exposure by turning the Shutter Dial. Thus, the subject will look better against a clear background. Because the shutter speed is slow, it is recommended to mount the camera on a tripod to avoid blurred exposure.4www.butkus.org

<Daylight flash> 
If you are shooting an object with strong backlight, or in front of a bright window, it will appear to be darker than its background. In this case, if you use flash as fill-in light, the extreme contrast between your object and its backgrounds will be balanced out. When shooting in the aperture-priority auto exposure mode, the overexposure warning "***" may blink because the shutter speed automatically switches to 1/90 sec. In this case, decrease the aperture until this warning light goes out. In the manual exposure mode the shutter speed must be set to 1/90 sec. (by automatic switching) or " X " on the Shutter Dial. Then, adjust the aperture properly by checking against the " "***" " and "***" marks in the viewfinder. In this mode, you can use flash as fill-in light.


When the lens is focused on a subject, not the subject itself, but also a certain zone in front and behind of it will appear as acceptably well focused. This range is called the depth-of-field of a lens and it changes in following ways: 

1. The smaller the aperture, the deeper the depth-of-field, and vice versa.

2. The longer the subject distance, the deeper the depth-of field, and vice versa.

3. The zone of sharpness behind the point on which the lens is focused is larger than that in front of it. Also the shorter the focal length, the wider the range of depth-of-field, and vice versa.

Certain zoom lenses are not provided with a depth-of-field

Infra-red' Compensation Mark
To take infra-red pictures with B & W infra-red film (by using an infra-red filter), compensation on focusing is necessary. The point of focus will shift slightly relative to that in normal photography. For this purpose, an infra-red compensation mark is provided on the depth-of-f ield as normal, then put on the filter, shift that distance to the infra-red mark and shoot.

· If you use color infra-red film, follow the instruction sheet in the film package.4www.butkus.org

Release Socket/interchangeable Camera Back

<Release Socket> 
This socket may be used to attach remote control units as the Yashica/Contax Cable Switch. It transmits electric signal from them to operate the shutter

<Interchangeable Camera Back> 
You can replace the Camera Back with an Data Back DA-2 (optional accessory) for imprint date or time on your picture. The Camera Back can be detached by pushing down the Back Cover Release Pin.

Attaching the Accessories

<Stray Light Prevention Adaptor> 
A stray light prevention adapter has been supplied with your camera for preventing stray light from entering the viewfinder when using the self-timer or remote control system. Slip it onto your carrying strap as illustrated, and use it by fitting it onto the viewfinder eyepiece.

<Attaching the Strap>
Attach the Strap to the camera's Strap Lug as shown.

<Attaching the Eyecup> 
Attach the Eyecup to the Viewfinder Eyepiece as shown. The optional FL-type Diopter Lenses are attached as shown. The Eyecup can be placed over the Diopter Lens.

Battery Check
The lamps "", or "" and "" in the viewfinder are also used as battery checking indicators. If the battery voltage is nominal, the lamps will light up steadily or blink at a constant frequency (6 times per second). If the battery voltage is low, the lamp will no longer light up steadily or it will blink with irregular interruption. In this case, the batteries still have enough power for exposing the film remaining in the camera, but you will have to change them after exposing the entire roll of film. If the battery voltage falls below the specified level, all lamps in the viewfinder will blink and you cannot trip the shutter. Replace all batteries immediately with new ones (four AAA size Alkaline batteries).

· Fast blinking - aperture warning

· Slowing blinking - batteries warning

Battery Precautions

· Always replace all four batteries at the same time with new ones of the same type and brand. Never mix new and old ones.

· Battery performance would be reduced in extreme low temperatures (i.e. 0°C or below). If you are shooting in extreme cold weather, use new batteries and keep the camera warm before shooting. Even if batteries performance is reduced temporarily in low temperatures, it will recover once room temperature is resumed.

· Wipe both caps of battery cell clean with a piece of dry cloth before use. Batteries soiled by sweat, oil or grease will cause poor contact and malfunction.

· If you are going on a long trip, bring spare fresh batteries along with you.

· Do not throw used batteries into a fire or attempted to take then apart because it is dangerous.

· To take full advantage of the outstanding features of this camera, we recommended you to use our interchangeable lenses and accessories designed for it.4www.butkus.org

· We are not responsible for the malfunctions and trouble resulting from the use of products by other makers. It is advisable to use our interchangeable products.

Camera Care/Camera Storage

<Camera Care>
· Do not expose the camera to extreme temperatures (e.g. on a beach in summer or in a parked car under direct sunlight, etc ) for a prolonged period of time. The camera, film and batteries may be adversely affected.

· After taking picture at the seaside or on mountains, clean the camera thoroughly. Salty air would cause corrosion, sand and dust would adversely affect the internal precision parts of the camera.

· To remove dust and dirt on the lens and viewfinder eyepiece, use an air blower or a soft lens brush. Wipe off fingerprints lightly with lens tissue. Remove dust and soil on the mirror surface with a lens brush.

· The lens and viewfinder glass may be clouded if the camera is carried into a warm room from outdoors where it is cold. Cloudiness caused by condensation disappears quickly. But, it is recommended to avoid sudden changes internal corrosion.

· If you are going to use the camera for important events such as an overseas trip or wedding ceremony, test it before hand to make sure it functions properly. It is also advisable to bring spare batteries along with you.
