The EDINA is a precision 35 mm. camera and available in two Models – Model II with coupled rangefinder and Model I without coupled rangefinder.
The rangefinder of the EDINA II is designed to the highest precision so that the most accurate results will be obtained. It is coupled with the helical focusing mount of the lens in a new and simplified manner that guarantees smooth operation. This rangefinder can easily be adjusted in the event that the camera should be dropped or it should otherwise become necessary to do so.
All models have a rapid winding lever which permits you to take pictures in very fast sequence so that serial shots can be taken with the greatest of ease. With two rapid movements you transport the film and cock the shutter, so that no separate operation is necessary for the latter. This also warrants double exposure prevention. The shutter is released smoothly with a knob located on the body of the camera convenient for operation with your right hand so that you can release the shutter immediately after winding it. In the same manner, you do not have to remove the camera from the eye when setting the distance on the Model II with coupled rangefinder. Simply set the distance and wind the shutter while focusing – then release the shutter.
Loading the camera is simple and can be done extremely fast. Detailed instructions are given in the corresponding chapters of these instructions. Since this is a precision instrument, we urge you to study the instructions carefully before using your camera. We recommend that you make a couple of tests with one roll of film first. Should you encounter any difficulties in operating your camera, do not attempt to make repairs on your own.
Your EDINA Camera is designed to take standard 35 mm. cassettes for 20 or 36 exposures.
The first step is to open the back of the camera. This is done by pushing up the latch of the camera back. Then the rewind knob has to be pulled up and the film cassette is inserted into the camera with the leader facing in the direction of the take-up spool.
Turn take-up spool (without using the lever) until two slots become visible. Bend the end of the film about half an inch and and insert the tongue of the film into the slot in the take-up spool. It does not matter whether the film tongue is on top or bottom or if there is no tongue at all (as in bulk film).
It is advisable to move the film by hand until the perforations properly engage the sprockets. Close the back of the camera by pushing the latch down. To eliminate that portion of the film exposed by loading the camera and to bring fresh film into taking position, turn the winding lever three times. Be careful to move the lever each time as far as it will go. Push the body trigger release and repeat operation. Now the film is in taking position.
The film counter indicates the number of pictures still remaining in the cassette and, therefore, must be set on “20” or “36” (depending on the film used). The film counter is set through the setting knob either with your fingernail or with a small coin. The film counter can be moved in either direction. You are now ready to take the first picture.
Measure the distance from the camera to the object and set the corresponding distance on the distance setting ring. If there should be no corresponding figure on the ring to the measured distance, you have to move closer or back away from the object, or, if that is not possible, select a setting between the two closest figures.
EDINA II with coupled rangefinder
Focus with your left eye through the rangefinder window while turning the distance setting ring of the lens with your left hand. You will notice that the image in the window consists of two parts. The camera is in focus when the two images are in a straight line (see picture).
By turning the outer ring the shutter speed selected will appear in the small cut off. The number “1” means 1 sec. “2” however 1/2 sec., 5 1/5 sec., and so on. “B” means time exposure – as long as you press the body release the shutter remains opened. Time exposures and all exposures longer than 1/25 sec. must be done with a cable release. In this case a tripod or another support must be used. For long exposures of a few seconds we recommend a locking cable release. Some shutters as the “Pronto” shutter are equipped with delaying action device (selftimers). To use the selftimer you push the lever with the red button clockwise, release the shutter and move yourself into the taking position facng the camera. Distance, shutter speed and diaphragm setting as usual. The delay is about 15 seconds which gives you ample time to get yourself into the picture.
Diaphragm opening – the shutter of the camera controls the amount of light permitted to enter and register on the negative. On the top of the shutter you will notice markings from f/2.8 or f/3.5 to f/16. These are the diaphragm openings or stops. Open the back of the camera (when not loaded of course) set the shutter speed on “B”, wind the lever and advance the film sprocket as far as it will go to the right once by hand. Then press the body release and keep it down, if desired, with a locking cable release, while holding the camera up to your eye. The diaphragm can then be seen against the light. Please note that of the pointer from f/2.8 to f/16 is moved, the opening behind the lens gets smaller. This variable diaphragm opening controls the amount of light that can enter the camera at any given shutter speed. When taking pictures indoors, when all the available light is required to enter the camera, use a larger diaphragm setting such as f/2.8 or f/3.5. When taking pictures in sunlight, when the prevention of too much light from entering the camera id desired, a small opening of f/8 should be used.
Depth of Field
An important characteristic of lens operations of worth noting. When a small diaphragm opening is used, the resulting snapshot has a large depth of field. Objects in front of and in back of the focusing distance will register sharply in focus. When a large diaphragm opening is used, only a short distance before and after the focusing distance will also be in focus. On the shutter is engraved the depth of field table which indicates to you the depth of field for the given distance and diaphragm. The distances on the focusing ring opposite the diaphragm numbers give you the range of the sharpness. For example:-
|Diaphragm||Distance||Depth of Field|
|8||7 feet||5.5 feet to 10 feet.|
|8||10 feet||7 feet to 18 feet|
The amount of light which falls on the film can be controlled in two ways:1. by regulating the diaphragm opening
2. through the various shutter speeds
The stopping down of the diaphragm opening gives you the advantage of a greater depth of field. In general use a speed of 1/25 or 1/50 sec. and regulate the diaphragm according to prevailing light conditions. However, when pictures of fast moving objects have to be taken a faster speed, say 1/100 sec. must be selected. In this case, of course, a larger stop must be used.
We recommend to use one of the light meters sold by your photo dealer. If you are a colour enthusiast an electrical exposure meter is useful because of its accuracy.
To facilitate the taking of pictures for the beginner, there is a so-called universal setting. You set your camera for the speed of 1/25 or 1/50 sec. depending on the light, and you set your distance to 20 ft. The diaphragm opening should be f/8. In this position most of the objects in front of the camera will be sharp in the picture and the exposure time will also be correct. However, you can use this universal setting only on certain days and only when you use black-and-white film since you have a wider exposure latitude with black-and-white film. Colour pictures have to be exposed very accurately. If you use colour film we suggest that you follow the instructions given by the film manufacturers. Also if you want to take pictures of moving objects, you will have to use a faster speed and a large diaphragm opening. Follow rules about shutter speeds for moving objects. Colour pictures should not be taken with a diaphragm opening slower than f/6.3. Our lenses are therefore specially corrected for the diaphragm opening speed range from full opening to f/8. We recommend consequently to stay within this range even with black-and-white film and if necessary to use instead a shorter exposure time.
Taking the Picture
Hold the camera with both hands so that the viewfinder window is in front of the right eye. Trip the shutter with the firefinger of your right hand and wind the film with the thumb of your right hand. As pointed out in the introduction, it is this way possible to take pictures in fast sequence without removing the camera from your eye, and on the model with coupled rangefinder you can set the distance at the same time.
After having made your exposure you move your film for the next picture by twice winding your lever. Our camera is designed for double winding of the lever, because it takes the same time as single winding (the way is the same) but it is more comfortable. The lever comes back into the original position automatically. While transporting the film the rewind knob turns and you can observe if the film is properly transported.
After you have taken all the pictures, the film must be rewound into the original cassette. Move the rewind button to rewind position (to the left). Then rewind the film into the cassette by turning the rewind knob clockwise. As long as there is still film in the camera you feel the effort of winding, which stops as soon as all of the film is back in the cassette. You can further control this operation by observing the numbers of the counter which moves backwards, and when the film is rewound it shows again No. 36 or 20 (depending on the film used). To facilitate the rewinding operation a msall lever is inserted in the rewind knob, which has to be pushed up.
On the shutter there is a flash synchro nipple into which you insert the plug of the flash cord. All of the shutters are synchronized for the speeds of 1/50 and slower for flash and bulbs and at all speeds for electronic flashguns. The Prontor SV shutter however is fully synchronized, that means, you can take flash pictures with all speeds using flash bulbs and electronic guns.
Treatment of the Edina
It is advisable to keep the camera in the Everready Case at all times since the case will protect it from dust. The case is designed so that it does not have to be removed when taking pictures.
Treat your EDINA camera gently and carefully. From time to time the interior of the camera has to be cleaned and the dust removed with a fine camel hair brush, especially when you take the camera to the beach, fine sand may enter and cause scratches on the lens and the film. The lens and different parts of the camera should be cleaned with a soft cotton cloth (which has been washed several times without detergents) soaked in alcohol.
Table of Depth of Focus
All measurements given in the table, the distances focused as well as the distances given for the depth of focus, are to be taken from the objective glass only. All figures in feet.
