Manual Photography

To manually set the exposure with your Konica FS-1, merely set the lens to any aperture other than the AE position. A red LED will pulse at the "M" mark in the viewfinder to signify manual operation.

 


The Konica FS-1 through the lens (TTL)--automatic exposure (AK) system operates at all times, even during manual operation displaying the correct exposure in the viewfinder, for the scene, even though you have set an aperture and shutter speed combination manually.4.butkus.org


Selection of Shutter Speed
The shutter speeds range from B 2, 1 to 1/1000 sec. The shutter speeds are calibrated on the dial. An intermediate point between readings is not usable, so make sure that the dial clicks into position.

Your camera is equipped with a system of giving priority to shutter speed. Depending on the brightness and movement of a subject, a shutter speed may be optionally selected.



Basis for Shutter Speed Selection
In a broad term, the recommended shutter speed is 1/125 to 1/250 sec. for outdoor photography and 1/30 to 1/60 sec. for outdoor shooting. For a moving subject, determine the shutter speed in the following manner:

1) If you want a moving subject to look still in a finished picture select a fast speed from a range of 1/250 to 1./;000 second.

2) If you want to stress the movement of a moving subject, select a slow speed from a range of 1/30 to 1/60 second.



Aperture vs Depth-of-Field
When the lens is focused on a subject there is a range around the subject which will be clearly be delineated in a finished picture. This range is known as a depth of field.

1) The larger the aperture value (i.e., the smaller the lens aperture), 2) the longer the camera-to-subject distance, 3) the shorter the focal length, the greater the depth of field. The depth of field is shallow for the area in front of the focal point and deep for the area behind. The actual depth may be known by checking the depth-of-field scale.

Reading of Depth of-Field Scale
For a depth-of-field scale, identical aperture readings are calibrated in parallel on both sides of the distance index mark. The range which is sandwiched between a pair of identical aperture readings is a depth of field in which the image will be clearly delineated in a finished picture.

For example when the camera-to-subject distance is 7 m with a 40 mm standard lens, the depth of field will be about 5~10 m for f/4 and about 3 m to infinity for f/8.

The red colored "4" on the depth-of-field scale is an infrared compensation mark, which is used for a compensation of the focal point with the use of infrared film. For example, if the camera-to-subject distance is infinity, the infinity mark will be brought in line with the infrared compensation mark.

When priority is to be given to the determination of a lens aperture, turn the shutter speed dial while looking through the finder, slightly press down the shutter button and change the shutter speed so that the LED will be turned on at the reading of the desired lens aperture.

Exposure Compensation for Backlight Photography
In normal TTL-AE photography, the correct exposure may be obtained. However, in a situation where the subject is in backlight, where there is much difference between the bright and dim parts of the main subject's periphery, or where it is desirable to produce special effects in a finished picture, the exposure may be compensated to raise the effects.4.butkus.org



In a situation where the subject is dark against a bright background scene

The AE responds to the overall bright background and in some cases the subject may appear dark (underexposed). For such situations:

1 ) You may change the ASA scale by half to compensate for the backlight situation and shoot in AE mode.

Example: ASA of film 400, change ASA scale to 200 or 2) You may note the aperture LED in the viewfinder and manually set the aperture ring on the lens by one stop. For example: meter reading AE=f11, set lens manually to f8.

In a situation where the subject is bright and background dark, reverse the above instructions

1) Double the ASA number. Example: 400 to 800 or 2) You may read the aperture in the viewfinder and set the lens manually to the next f stop. Example: meter reading f5.6--set lens manually to f8.

· After special exposure photography, be sure to reset the AE mark, and/or reset the ASA speed dial to the correct sensitivity of the film.


Stopped-down Metering Method
With a Hexanon AR lens bearing an AE mark, the correct exposure is determined at the full opening of the lens both in AE and manual photography, to determine the correct exposure in stopped-down metering situation.

1 ) A manual pre-set aperture ARP lens or a manual pre-set ARM lens is in use.

2) The AE cannot be used because of the use of an extension ring or bellows.

3) A lens of some other make is used on a lens mount adapter.


Exposure Determination

For stopped-down metering, look through the finder and turn the aperture ring or the shutter speed dial, while the shutter button is lightly depressed.

When the LED positioned between the "M" and "f/1.4" mark glows, you have set the correct exposure.

· Stopped-down metering tends to be affected by the rays inversely straying into the eyepiece. Prevent the rays with an eyecup or some other device.

· Stopped-down metering is also done for microscopic photography. Adjust the shutter speed according to the brightness of the light source.


Electronic Flash Photography
During the night or in a dark room where AE photography is unsuitable, the use of the Konica X-24 Auto electronic flash is recommended. The X-24 flash was especially designed for use with the Konica FS-1camera to eliminate complicated exposure calculations.


To use the Konica X-24 Auto Flash
1) Use four AA Alkaline or nickel cadmium rechargeable batteries to power the Konica X-24 auto flash.
2) Attach the X-24 auto flash to the hotshoe a top the Konica FS-1 camera and set the F value scale to distance green (f5.6) or close range red (f11).
3) When the X-24 autoflash is charged --ready to shoot

a. the shutter speed will automatically change to 1/100th second flash sync speed.
b. the aperture will automatically change to f5.6 or f11 as preselected on the X-24 scale.
c. the LED in the viewfinder at f5.6 or f11 will pulse indicating that the flash is ready.

If the picture is taken before the flash is ready, the picture will be exposed in AE mode. Be sure to observe the under/over exposure warning signals.

· With flash photography using the self timer, check that the charge is complete before depressing the self timer switch.4.butkus.org

The range for automatic flash is:
ASA 100 film--f5.6 0.7 - 4.3m (2.3 - 14.2 ft) f11 0.7 2.1m (2.3 - 7.0ft)
ASA 400 film--f5.6 1.0 - 8.6m (3.3 - 28.4 ft) f 1 1 0.7 4.3m (2.3 - 14.2 ft)

Use of Other Types of Electronic Flash Units
An electronic light with a hotshoe, such as the Konica X-28, X-20 and X-14, may be electrically connected simply by fitting it to the hotshoe clip. With an electronic light without a hotshoe connector, insert the plug of its cord into the X flash contact taphole of the camera body.

1) set the shutter speed to 1/60 sec. for all types electronic flash except Konica X-24 Autoflash.
2) set the lens aperture manually per the instructions of the electronic flash unit.
3) when using automatic flash units such as the Konica X-24, set the lens aperture as indicated by the autoflash.
4) for manual flash units, determine the correct aperture to set by dividing the guide number by the camera to subject distance. Example: Using ASA 100 film with a Konica X-20 flash, you will get a guide number (GN) of 20, divided by the distance (5 meters) results in a lens aperture of f4 (20 . 5 = 4).


Use of the Strap
The strap for the Konica FS-1 is constructed of wide, very durable nylon which can be used either as an adjustable neck strap or functional hand strap.


· To use as Neck Strap
1) Open the lock at the tip of the suspension ring.
2) Insert the lock through the strap eyelet on the front of the camera body and close it. Make sure that the side bearing a Konica mark faces outside.
3) Insert the other end of the strap through the eyelet on the back of the camera body and fasten the drum-shaped button into the long cut of the strap.
4) The length of the neckstrap can be adjusted by flipping up the lever at the mid point of the strap.

· To use as a Hand Strap
1 ) The shorter strap fitted to the back is for use as a hand strap. Hold the base of the metal connector with finger tips.
2) Insert the hand strap about 3 cm, and push down the stopper pin outward.
3) Pull out the straps and separate them. Detach the longer one from the camera.
4) The adjustment ring fitted to the hand strap may be used in tightening the wrist with the strap or preventing light from straying into the eyepiece.


Precautions for use
· At cold places where the temperature is below 0° C, the batteries will run down. Warm your camera before you use it.
· When the battery cells are to be exchanged, use AA alkali manganese dry cells. All the four cells must be replaced.
· When you know you will use the camera at a cold place, make sure that you will have spare battery cells and keep them warm with your body or in some other means to prevent a drop in the battery performance.

O Konica X-24 Automatic Electronic Flash
This flash unit was especially created for use with the Konica FS-1 camera. It conforms to the FS-1 camera contours and functions in collaboration with the Konica FS-1 central processing unit (CPU) for automatic flash operation.

When mounted stop the Konica FS-1 camera, you only set the automatic distance control (green f5.6 or red f11). When the X-24 is turned on and reaches 95% of flash power, it automatically signals the Konica FS-1 camera to change shutter speed to a fast 1/100th second, to change the lens aperture to f5.6 or f11 and displays a blinking LED signal in the viewfinder that the flash is ready.


o Cable Switch - This switch type cable release is used in place of the conventional cable release since, the Konica FS-1 features an electromagnetic release mechanism. When this switch is connected to the terminal of the camera, it is possible to trip the shutter by operating the hand-held switch. This switch is useful for bulb exposure and also close-ups, telephoto shots, and also helps cancel out camera shake when using slow shutter speeds.


o Remote Control Switch - The cord is 5m in length. Operating the switch on your end of the cord, the shutter may be released at a place away from the camera.

O Double Cable Switch - The double cable release switch for the use of Auto Bellows with an automatic aperture makes it possible to use any Auto Bellows on the Konica FS-1.

O Interval Timer (To be put on sale)
This device allows photographs to be taken repeatedly at fixed intervals of time. When it is mounted on the camera and the switch is turned on, the shutter is repeatedly tripped at the pre-set

o Close-up Lens - This lens permits AE close-ups simply by screwing it onto the front of the lens and mounting it in place. This makes close-up photographs of plants and flowers as well as copies of documents and pictures easy work.

o Angle-Magnifinder - This helpful gadget makes it possible to look into the viewfinder from above the camera and it comes in handy for when pictures are to be taken at a low level such as in copying, close-ups and micro-photography. Furthermore, when the lever is rotated, the image in the center of the viewfinder is enlarged two-fold with the magnifying glass and so focusing can be performed very accurately for close-ups, copying, telephoto photography and micro-photography.

O Cable-less Switch (To be put on sale)
This switch is made up of a receiver, which will be fitted to the camera, and a transmitter, which will be used on your side. The infra-red rays transmitted by the transmitter will be intercepted by the receiver, making it possible to operate the shutter with electric signals. Only the Konica FS-1 with an automatic wind AE mechanism makes unmanned photographing possible and fully displays its performance in taking, say, ecological pictures of animals, to which man cannot come
