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,

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)

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.
 
 

· 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.

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.

· KONICA Filters

As the KONICA Autoreflex T is of the TTL type, there is no need to worry about a filter factor according to the type of filter used on your camera. It is advisable to use a filter to boost photographic effects.
 
 

Color	Name	Effects
Colorless	UV (L 39)	Absorbs only ultra-violet rays. Used for color photography since it produces no effects on colors. Also serves as a lens protector.
Light Yellow Yellow Dark-Yellow	Y I (Y 44)  Y 2 (Y 48)  Y 3 (Y 52)	Absorbs ultra-violet rays, purple and blue. For landscapes, portraits and snapshots. Assures proper contrast in brightness and dimensional effects. For black-andwhite.
Orange	01 (0 56)	Produces powerful contrast due to its wide absorbing range. For mountains, distant scenes and architecture. For black-and-white.
Red		Extremely strong contrast. Daytime landscapes sometimes look as if they were night scenes. Can be used with infrared film. For black-and-white.
Yellowish green		Brings film characteristics closest to the human eyes. Shows colors naturally. For outdoor portraits as it has the same characteristics as the light yellow filter.
Light gray  Gray  Dark gray	ND 2  ND 4 ND 8	Absolutely no effect on colors reduces light. Used with  both color and black-and-white. Light IS reduced 1/2 with ND2, 1/4 with ND4 and 1/8 with ND8.
Light pink SKYLIGHT		Like the ND filter, it absorbs ultra-violet rays Prevent distant scopes with sky and shades from becoming bluish in color pictures. For color film.
Light amber	A 2	Absorbs blue light from shadows; also from cloudy scenes. Use to reduce color temperature for daylight type color film.
Light blue	B 2	Absorbs red from scenes taken at sunrise and sunset. Raises color temperature for daylight-type color film.
Blue	B 8	Used with flashbulbs (clear bulbs) and daylight-type color film to reduce red tone and raise color temperature.
Dark blue	B 12	Used with photo-reflector lamp (3,200°K) and daylight type color film to reduce red tone and to raise color.

MAINTENANCE OF CAMERA AND LENS

· In wiping the camera body and lens barrel, take off dust with a brush and blower before they are cleaned with a piece of soft cloth. Use a brush or blower in taking out dust inside the camera and do not go as far as to wipe the mirror, which is a special plane mirror.

· Use a soft brush in taking off dust on the surface of the lens. in the event that it is marred with fingerprints or water drops prepare a piece of wed washed, clean cotton cloth and dampen it with a small quantity of absolute alcohol (it is advisable to mix it with ether). Lightly wipe the lens surface in a whirlpool starting at the center.

· To store the camera and lens, choose a place free from moisture. Take out the mercury battery cells. The best and safest method will be to keep them in a polyethylene bag together with a desiccant, such as silica gel.
