The KONICA Autoreflex T's TTL meter takes two 1.3V mercury battery cells as its electric source. Wipe the separately enclosed mercury battery cells with a piece of dry and clean cloth and put them into the mercury battery chamber.

(Webmaster: this is a mercury battery, not available for sale in the U.S.  Check my web page for Mercury Battery Replacements.   There are several options.

1. Turn the cover of the Mercury Battery Chamber (39) counterclockwise with a coin or something alike and detach it from the chamber.

2. Insert the two cells into the mercury battery chamber the "+" side up, as indicated in the figure printed on the seal inside the chamber.

Turn the cover of the mercury battery chamber clockwise and make sure that it has been screwed tightly.4.butkus.org

Meter Switch

The meter-switch will be put ON when the Lock Lever (3) placed under the Shutter Button (1) is turned so that it comes in alignment with the red index point.

Unless pictures are to be taken, set the lever to "L" and the switch will be kept put OFF, preventing the mercury battery cells from accidentally running down. At the same time, the shutter button wish be locked. Use this system when the camera is to be carried around with the film cocking lever wound.
 

Check of Batteries

The expected span of serviceability of a mercury battery cell will be over one year in normal use. With the span of its serviceability getting to a close, its voltage will suddenly diminish. The degree to which the cells have run down may be checked while pictures are taken, but it will also be possible to check it in the following manner.

1. While the Lens Interchanging Button (23) is depressed, turn the lens counterclockwise and detach it From the camera. (Refer to Page 54.) There is no need to dismount your lens, if it is not an automatic aperture one with an EE mark.

2. Grip and lift up the place outside the Shutter Speed Dial (17) and set the film speed to ASA 100.

3. Turn the shutter speed dial and set it to 1/125 sec.

4. While looking into the viewfinder, depress the Battery Check Button (27) on the bottom of your camera. The capacity of the battery cells will be adequate if the Meter Needle (45) is found to be swinging under the Battery Check Mark (46). If the meter needle is no longer able to reach the mark, replace the battery cells with new ones.

As mentioned above, every index point for the battery check is indicated in red. In a word, the essential thing will be for the meter needle to swing under the red mark after the film and shutter speeds are aligned with the red marks.

· The meter takes two 1.3V National H-C, Mallory PX-675 or Eveready EPX-675 mercury battery cells. Care must be exercised in selecting the cells as there are cells which look identical in shape but differ in stipulated voltage, such as battery cells.

· In the event that your camera is not to be used over a long span of time, take out the mercury battery cells and keep them in a place free from moisture.

FILM LOADING

The KONICA Autoreflex T takes 35mm rod film, which comes in a cartridge. For film loading, avoid the direct sunlight and do it in the shade. If there is no shade, one way would be to use the shadow of your body.
 
 

1. Put the Back Cover Lock (24) and open the Back Cover,
2. Put a film cartridge into the Film Chamber (26) as though it skid into the chamber at a slant from above the underside.

3. Pun out the film while the cartridge is lightly pressed down and then choose any slit of the Film Take-up Spool (32) into which the film tip may be inserted with ease and insert the film into the slit.

4. While lightly pressing down the cartridge, turn the Film Cocking Lever (13) and take up the film on the spool. Ascertain that the teeth of the Sprocket (31) are in gear with film perforations before the back cover is closed. Depress the back cover with a finger tip, and it will be closed with ease.4.butkus.org

5. Flip up the Film Rewind Crank (19) and turn it in the direction indicated by an arrow mark on it to reduce the slack of the film.

6. Turn the film cocking lever until it does not move further and depress the Shutter Button (1). Repeat this action tin the figure "1" comes in alignment with the index mark in the window of the Film Counter. (2). If the him is transported in the correct manner when the film cocking lever is turned, the Film Rewind Knob (20) will revolve counterclockwise. If it
does not turn counterclockwise, rewind the film (see Page 48) and

· Turn the film cocking lever until it does not move further and the film will be transported by one frame and the shutter charged at the same time. The mirror and the automatic aperture will also be set. Simultaneously, the film counter will advance by one reading.

7. Set Film Speed (ASA)

Lift and turn the external ring of the Shutter Speed Dial (17) and align the reading equivalent to the speed of the film loaded in your camera with the index mark of the Film Speed Indicator Window (ASA) (14). When they are aligned, the ring drops and is fixed into position.

· The ASA and DIN scales visible in the film speed indicator window indicate the degrees to which film is sensitive to light. The film speed of your film is indicated on the box in which it is contained and in its instruction booklet. (Figures in brackets refer to intermediate points of sensitivity.)

SHUTTER

A shutter is designed to control the amount of light reaching the film surface in terms of time and photographically to fix an image of a subject on it. The shutter speed scale has calibrations of B and I to 1/1000 sec. and the denominator of each speed is indicated on the shutter speed dial. The shutter speed may be adjusted simply by bringing a reading in line with the index mark

· Shutter speed calibrations are also visible in the viewfinder, thus making it possible to ascertain the speed while looking through the viewfinder.

·"B" stands for bulb exposure and is used when there is the need for the exposure of over one second. (Page 53)

· The red figure of "125" is the maximum shutter speed for synchronization with an electronic light.

· Do not turn the shutter speed dial when the shutter button is depressed.4.butkus.org
 

APERTURE

The lens aperture is designed to control the amount of light reaching the film surface in terms of area and the depth of field (see Page 40). Your camera's EE system will automatically determine the correct aperture value, once the EE mark on the aperture ring is aligned with the index mark. Manual aperture is also usable (Page 35). In either event the fully automatic aperture system will work and the lens will be stopped down to a determined f-number only during the split moment when the shutter is depressed and then automatically return to the full opening after a picture has been taken.

· The amount of light going through the lens will reduce in proportion to a rise in the aperture value. The correlation, as indicated in the above figure, is such that the brightness of the lens reduces by half in proportion as the aperture enlarges by one reading.

· The lens having the EE Release Button (12) at its aperture ring is equipped with an EE lock. In the event that the camera is released from the electric eye system and used for manual aperture, depress this button and turn it.

· The aperture is continually variable, and therefore an intermediate point between readings on the aperture ring is usable.
 

METERING SYSTEMS OF TTL METER

The KONICA Autoreflex T's TTL meter not only measures light reaching the film plane through the lens but also incorporates a variable metering system in which the spot metering method, the center spot metering method and the all-frame average metering method are automatically selected, depending on the coverage of the lens. This system makes it possible to measure light with the lens kept at its full opening while looking through the bright viewfinder and to measure light with the lens stopped down to a desired f-number.

It is the most ideal metering system in which deep hoods are fitted to the two compound CdS.cells on both sides of the viewfinder . eyepiece and the light intake device is slanted inwards and in which the brightness of a subject whose image is formed on the focusing glass plate as indicated in the figure is measured while a curvature of the
 
 

NOTE: The KONICA Autoreflex T does not take any fully automatic EE aperture lens prepared for the Autoreflex as it is. Make sure that you use it after it has been remodeled into a lens for use on the Autoreflex T (with f-numbers). Remodeling work is quite simple.4.butkus.org

LOOKING AT METER INSIDE VIEWFINDER

F-NUMBER FOR CORRECT EXPOSURE: When the Meter Needle (45) stops within the range of correct exposure, the f-number on the aperture scale (47) to which the meter needle points is the aperture to which the taking lens will be set when the shutter is released for a shot.

CORRECT EXPOSURE RANGE: For an AR lens which is not f/1.2 in brightness, the Mark Indicating the F-number (44) at the Full Lens Opening shows the f-number at the full opening of the lens used on your camera. If the meter needle is aligned with this red mark, pictures will be under-exposed. The mark indicating the f-number at the full opening of the lens win move down if the meter is not coupled. In other words, the mark will also show the range where the meter is coupled. In EE picture-taking, therefore, the area sandwiched between the upper and lower red marks is the correct exposure range.

INDICATION OF SHUTTER SPEED SCALE: The speed at which the shutter will be released is indicated on the Shutter Speed Scale (42) in the lower part of the viewfinder

MANUAL INDICATOR MARK: When the EE device is released and the camera is set to manual picture-taking or when the stopped-down metering system is used, the Manual Aperture Indicator Mark (43) "M" will appear over the meter window, showing that a picture is not to be taken under EE system.

INDEX POINT FOR STOPPED-DOWN METERING: For stopped-down metering, the meter needle will be brought in line with the Index Point for Stopped-down Metering (41) to secure a correct exposure. (Refer to "Stopped-down Metering" on Page 57.)

BATTERY CHECK MARK: The Battery Check Mark (46) is used to check the serviceability of the mercury battery cells which serve as the electric source of the meter. (Refer to 'Battery Check" on Page 16.)
 

ELECTRIC-EYE PHOTOGRAPHY

(Light Metering at Full Lens Opening)

This method is commonly used when pictures are taken under the EE system with an AR lens having the EE mark.

1. Set Your Camera to EE Mark.

Turn the Aperture Ring (11) arid bring the EE Mark (4) in line with the index point. The EE lock will click into position.

2. Determine Shutter Speed.

Turn the Shutter Speed Dial (17), select a reading on the Shutter Speed Scale (16) suitable for your subject and bring it in line with the index mark. In normal circumstances, it is convenient to set the shutter speed to 1/125 see, for outdoor shooting and 1/30 sec. for indoor picture-taking.

3. Look Through Viewfinder.

Train your camera at the subject look through the viewfinder, focus the lens, flame your subject and look at the Meter Needle (45) in the viewfinder. If the meter needle is not aligned with the upper or lower red mark (exposure limit mark), You will always be able to secure correct exposure.


(Webmaster: depending on the lens installed, the top red mark will cover more of the larger F-stops.   In the overexposure image note the red meter arm in the bottom of the metering range in the red.   Most other camera makers have the overexposure at the TOP of the metering range)

When the meter needle indicates an under-exposure, choose a slower shutter speed. When it indicates an over-exposure, select a faster shutter speed. Correct exposure may be secured as long as the meter needle is not aligned with the upper or lower red mark.

In the event that you want to give priority to the selection of a lens aperture over a shutter speed because of a desired depth of field, turn the shutter speed dial and make an adjustment so that the needle will indicate the desired f-number. No intermediate points between shutter speed readings are usable, so make sure that the shutter speed dial clicks into position.

·It will be quite meaningless even if the meter is visible within the correct exposure range with the shutter speed dial set to the `'B" reading. Do not use this method.

(Webmaster: in real English - In BULB the meter does not work.  It's experience and using the setting off the film box time)
 
 

Manual Picture-Taking

When a picture is to be taken while using the manual aperture button in ascertaining a depth of field or when it is to be taken with a flash light, release the EE system and set your camera to manual aperture. While the EE release button is depressed, turn the aperture ring, detach the EE mark from the index mark and determine an exposure according to the Manual Aperture Scale (8).

Hold Your Camera Tight

To take a sharp picture, the important thing is to hold your camera in a stable manner to prevent it from being jarred when the shutter button is depressed. Hold your camera in both hands and make it stable by holding it against your face and pressing the elbow of your hand supporting the camera against your body.

Particularly, it is more difficult to hold the camera, the long side up than to hold it, the long side down. It would be advisable to get yourself accustomed to the vertical holding of your camera.

· In taking pictures at slow shutter speeds or with a telephoto lens, the camera is likely to be jarred -if it is held in the hands. Here, the use of a tripod and a cable release is advisable. The tripod win be fixed to the Tripod Tap-hole (38) of the underside of the camera and the cable release to the tap-hole of the shutter button.
 
 

Focusing is done by turning the Focusing Ring (10) and watching the Micro Dia Prism (49) at the center of the viewfinder. When the lens is not focused, the image on the micro die prism looks rugged. The image is clearly visible, however, when the lens is accurately focused. The image of the periphery is also clearly visible. When an interchangeable lens, long in focal length, is used, it is difficult to observe the Micro Dia Prism. For focusing, it is advisable to use the Mat Plane (50). To ensure the accurate focusing of the lens, it is necessary to correct the eyesight of the viewfinder. Eyesight adjustment lenses are available for short- and long-sighted people.

The viewfinder is of the single-lens-reflex real-image type. Regardless whether the taking distance is far or short and whether or not a lens is interchanged, the image visible in the field of view is the same as that exposed on film.4.butkus.org
 
 

DEPTH OF FIELD

When the lens is focused on a subject at some distance, not only the subject but also a certain area around the subject will be sharply delineated in a photograph, and this area is known as a depth of field and has the following features.

a The bigger the f-number, the larger the depth of field,
b. The further the distance at which the lens is focused, the bigger the depth of field is.

c. When the lens is focused on a subject the depth of field is bigger for the section in Wont of the subject than the area behind the subject

d The shorter the focal length, the bigger the depth of field

The depth of field may be ascertained either with the depth-of-field scale or with the manual aperture, As for details, reference is made to the table of depths of field.

Using Table of Depths of Field: The Depth-of-Field Scale (6) is so calibrated that readings identical to those of the lens aperture are provided on both sides of the Distance Index Mark (51). For example, let us assume that the distance between the film plane and the subject on which a 57mm f/1.4 lens has been focused is 30 feet. The depth of field will be 22 to 46 feet for f/4 and 13 feet to on (infinity) for f/16.


 

INFRARED FILM COMPENSATION MARK:

The point of focus is somewhat different in infrared photography as compared to normal photography. After the lens has been focused as in normal photography, read the calibration on the Distance Scale (7) aligned with the Distance Scale Index Mark (51) and bring this reading in line with the Infrared Film Compensation Mark (52) before the shutter is released for a shot

Using Manual Aperture: The AR lens having an EE mark is equipped with a fully automatic aperture and therefore constantly set to the full opening. If you want to ascertain the depth of field while looking through the viewfinder turn the aperture ring to detach the EE mark from the index mark and determine an f-number. While depressing the manual aperture button (37), look through the viewfinder to ascertain the depth of field.

FOCAL PLANE MARK: The distances shown on the distance scale are those between subjects and the Focal Plane Mark  "" (18) which indicates the position of the film plane.

(Webmaster: In English - the distance marks on the lens means the distance from the subject to the film, not front of the lens)

(Two pages of detailed Depth Of Field tables were omitted)

USE OF SELF TIMER

The self-timer of the KONICA Autoreflex T is usable in EE manual and synchroflash photography. Use the self-timer when you are to take pictures of your companions and yourself and when it is to take the place of a cable release to prevent your camera from being accidentally jarred

After the film cocking lever has been wound, fully turn the SelfTimer Lever (5) and set the selftimer (the self-timer may also be set before the cocking lever is wound).

Depress the shutter button and the self-timer will be put to operation. The shutter will be released in about 10 seconds.4.butkus.org

· Instead of fully turning it, the self-timer may be set midway to reduce the time lag before the shutter release.

NOTE: When the self-timer is used in EE photography, note that strong light accidentally comes in the camera through the eyepiece as the shutter button is depressed and it leaves a strong impact on exposure. When the shutter button is to be depressed, therefore, look through the viewfinder or cover the eyepiece with a hand to prevent strong light from accidentally coming through the eyepiece. When the shutter button is to be depressed with your eye detached from the eyepiece, make sure that you do not stand right in front of your camera. Otherwise, the exposure will be determined on the basis of brightness of your clothing.

After a pre-determined number of pictures have been taken on the film loaded in your camera, the film needs to be wound back into the original cartridge.

If the back cover of your camera is opened without rewinding the film, the film win be exposed to light and all of the film will become useless.

· When the cocking lever no longer moves further after the advance of the last frame of the film, do not try forcibly to cock the lever Put the lever back to the original position.
 
 

1. Depress the Film Rewind Button (36) on the underside of your camera. Once it is depressed, the button will remain sunken.

2. Flip up the Film Rewind Crank (19) and turn it in the direction indicated by an arrow mark on the crank. This action will take the exposed film back into the cartridge.

3. The film rewind action comes to an end when there is a sudden easing of the load on the film rewind crank. Avoid the direct sunlight and open the back cover to take out the cartridge.

The film counter will return to the original position "S" when the back cover is opened.

· The film rewind button will also return to the original position when the film cocking lever is wound.
 
 

SYNCHROFLASH PHOTOGRAPHY

When pictures are to be taken during the night or in a dark room which does not permit EE photography, or when there is the need to use an auxiliary light during the daytime, use synchroflash bulbs or an electronic light in taking pictures.

For synchroflash photography, use Accessory Clip 3 which makes it possible to mount either a KONICA Cube Flash or a small electronic light on the eyepiece assembly.4.butkus.org

As your camera is equipped with a tap-hole each for Classes M and X, insert the plug into Tap-hole "M" for bulbs of Classes M, FP and MF (flash cubes) and into Tap-hole "X" for an electronic light.

·As for the KONICA Autoreflex T. the time lag is set at 18 millseconds for Class M and zero for Class X.


 

Exposure for Synchroflash Pictures

The Electric-Eye system is not usable for synchroflash photography and your camera must be set to manual aperture. The required lens aperture is computed by dividing the guide number of the used synchroflash bulb or electronic light with the taking distance.
 

For example, let us assume that a bulb of Class M is used, the guide number is 110 for the pre-determined shutter speed and the taking distance is 10 feet. For a correct exposure, your camera win have to be set to fill on the manual aperture scale, whereas 110 . 10 = 11. As regards the shutter speeds with which each synchroflash bulb or electronic light is synchronized, refer to the table.
 
 

B (BULB) EXPOSURE

Turn the shutter speed dial to align the "B" mark with the index mark and release the shutter, and the shutter will be kept during the moment when the shutter button is kept depressed. This process is usable when there is the need to expose film for more than one second

The bulb exposure cannot be used in the EE system. Set your camera to manual aperture.

· To prevent your camera from accidentally being jarred, the use of a tripod and a cable release is advisable. The KONICA Cable Release designed exclusively for the cameras is equipped with a T stop, which makes possible time exposure. In T exposure, the film win be kept exposed even if the finger is detached from the release.
 
 

To Dismount the Lens:

While the Lens Interchanging Button (23) is depressed, grip the silver part of the lens barrel and revolve it counterclockwise, Pun out the lens when the red dots of the barrel and camera have been aligned with each other.
 
 
 

To Mount a Lens:

Bring the red dot of the lens in line with the lens mount index mark (red dot) on the camera body and gently sink the lens barrel into the camera. Grip the silver part of the lens barrel and turn it clockwise until it clicks into position.4.butkus.org
 
 

NOTES:

· When the lens is detached, see to it that dust will not come in the camera and lens barrel and the lens surface will not be either scratched or marred with fingerprints. Under any circumstances, do not touch the inner parts of the camera.

· When the lens is taken out of the camera over a certain length of time, use a camera body cap and a mount cap which is snapped on to the rear part of the lens.

· When the lens is to be mounted on your camera, make sure that the lens is sunken into the camera while the red dots of the lens and camera are aligned with each other

PHOTOGRAPHING IN STOPPED-DOWN METERING SYSTEM

The AR lens provided with an EE mark is so designed that light can be measured at the full opening of the lens with automatic aperture either in EE or manual photography Exposure win be determined in the stopped-down metering system for the following instances, however.

1. When an ARP lens equipped with manually preset aperture or an ARM lens with manual click aperture is used 2. When automatic aperture cannot be put to use due to the utilization of an extension ring and bellows.
3. When a KONICA FS, FP or FM, or a lens produced by other camera manufacturer is used for the Autoreflex T together with a lens mount adapter. Exposure Determination

The aperture scale visible in the viewfinder is not usable for the stopped-down metering system. Turn either the aperture ring or the shutter speed dial and align the Meter Needle (45) with the Index Point for Stopped-down Metering (41) situated at the reading "f/ 1.4" to secure a correct exposure.

If the combination of aperture and shutter speed is improper, the needle win not come in alignment with the index mark. Pictures win be under-exposed when the needle is situated above the index mark and R will be over-exposed when it is located under the mark. Here, make an adjustment either with aperture or shutter speed.
 
 

· In the stopped-down metering system, the eyepiece tends to be affected by adverse light than in the system in which light is measured at the full lens opening. Determine the exposure while your eye is put as close to the eyepiece as possible. The needle swings in a very slow pace. Take a picture after it has been ascertained that the needle is aligned with the index mark.4.butkus.org

· In the event that a manually preset aperture lens is to be used on your camera, set the preset aperture ring to the reading of the smallest lens aperture in advance and then turn the aperture ring. This action will make easier the manipulation.

· Microphotogrphic pictures are also taken under the stopped-down metering system. Make an adjustment either with shutter speed or according to the brightness of the light source since no aperture is available.
