 PRACTICAL HINTS
• If the beginning of the film is not properly anchored on the take-up spool, it may slip out and will not be advanced on pressing the combi-plunger. To check: Unfold the rewind crank and let it hang down. Hold the camera horizontally to see whether the crank turns when you work the plunger. If it does not move, the beginning of the film has slipped out and must be fixed afresh to the take-up spool after opening the camera back (see page 6).
• Deliberate double exposures (e. g. for trick shots) are quite easy, despite the automatic double exposure lock. Proceed as follows: After the first exposure depress the rewind button, let go, and then fully push in the combi-plunger. This tensions the shutter without advancing the film, and you can make a second exposure. Then work the combi-plunger as already described.
If in doubt about the correct exposure, expose black-and-white film generously; a certain amount of overexposure does not matter much. Underexposure, however, always gives poor results. With colour film, exposure must be accurate; use an electric exposure meter at all times.

SPEED-SYNCHRONIZED FLASH SHOTS
The SYNCHRO-COMPUR makes possible flash shots of moving subjects at any shutter speed, including '/500 second. You can use the flash as the sole light source or else combine it with daylight or artificial light. With against-the-light shots you obtain excellent illumination of the shadow areas. All flash units on the market, including electronic flash, can be used with the shutter. Light-weight guns can simply be pushed into the accessory shoe; larger ones are mounted on a bracket which is screwed into the tripod bush and kept at the left-hand side of the camera (see. ill.). Picture

The flash lead which connects the flash gun with the camera carries on one end a round plug which is inserted into the sunk socket in the left-hand front door. The other end has the plug for the flash gun. This is often a safety plug with one thin and one thick pin which can be connected only in the correct way.

THE SETTINGS ON THE SYNCHRO-COMPUR SHUTTER
 Synchronization, exposure time, and aperture must be set according to the type of flash in use to ensure that the peak brightness of the flash coincides with the instant when the shutter is fully open.
Flash bulbs and electronic flash tubes vary in their firing delay times, and are classified in the table on the right. The synchronizing lever on the shutter must be set to either X or M, according to the type of flash in use (see ill.). Then set the shutter speed according to the values given under X and M and tension the shutter in the usual way.
Picture

For setting the correct aperture look up the so-called "guide numbers", which will be found in the instructions supplied with all types of flash. The correct aperture number will be found by dividing the respective guide-number by the distance in feet between the camera with flash and the subject. (Aperture = Guide-Number / Distance)

X-Setting
The contact closes at the moment when the shutter is fully open.


M-Setting
The contact closes a short time-corresponding to the firing delay of class M bulbs - before the shutter begins to open.

Electrical Data - Click here for chart of Flash Bulb Settings
The flash contact will carry the firing current of all types of electronic flash tubes. With flash bulbs it will carry a temporary load of 10 amps at 24 volts, thus allowing simultaneous firing of several bulbs connected in parallel. The longest permissible exposure time in this case is '/,o second.
Caution: The flash contacts must never be used to fire bulbs from 110 or 220 volt supply mains.
To avoid wiring up the leads the wrong way round, get an electrician to fix the cable to the flash gun in the first instance, since the outer pole of the flash socket is earthed.

 FLASH CASE
 The use of flash has become a matter of course for the up-to-date amateur photographer, not only after dark, but also in daylight. A flash bulb can give useful illumination to the often too black shadows of against-the-light shots; it can give the subject an effect of sunlight on a dull day, enable you to take hand-held snapshots with insufficient natural light, and so on.
To save you the inconvenience of carrying a flash gun separately, Voigtlander have created for you a Flash Case which carries in the smallest possible space both your camera and your flash gun. When you open the case and have inserted the lamp and done the setting you are immediately ready to use the flash gun because you can leave the flash lead connected to the camera even with the case closed.
Please ask your dealer for the detailed prospectus.		 Picture



THE "KONTUR" PUSH-ON VIEWFINDER
Quicker sighting of moving subjects and clearer presentation of pictorial scenes - those are the invaluable advantages of the KONTUR viewfinder. The large eye-piece of /s inch diameter gets rid of all the former viewfinder troubles, particularly for spectacle wearers.
Keep both eyes open while sighting the subject. The eye watching the subject directly will see it in its natural size and brightness, while the eye looking into the finder sees the frame outlining the picture area. You will see the two separate impressions as one single picture in your normal field of view.
A dotted line indicates the parallax error with close-ups from 3.3 to 6.6 feet. 
Caution: Never allow direct sunlight to reach the eye-piece of the finder. 		Picture Picture

Push the KONTUR finder into the accessory shoe from the front of the camera and push it back as far as it will go.


FILTERS - LENS HOOD
The high-efficiency lens of your camera will satisfy your most exacting demands for superb definition, but you can greatly enhance the mood of your pictures and obtain special effects with the help of filters.
It is surprising how often you can attain pictorial effects with these simple aids which are quite unobtainable without them, and they should not be missing from any photographer's equipment. Voigtlander Filters are made of massive, spectroscopically tested, glasses and ground absolutely parallel. Every filter is fitted in a bayonet mount and can remain in position on the camera when this is closed.		 Picture


The lens hood is indispensable for against-the-light shots and those taken with artificial light, for it screens the lens from all stray light. It also serves to protect the lens from raindrops in bad weather conditions.
The Leather Case for Accessories fits on the strap of the camera case and can take three filters and the lens hood.

CLOSE-UPS WITH SUPPLEMENTARY LENSES

Do not miss this highly interesting branch of photography which, unfortunately, so many amateurs neglect. Large-scale pictures of flowers, butterflies, and other small animals, small "objects d'art" etc. may yield effects of extraordinary beauty. With the help of Voigtldnder Focar Lenses you can, moreover, excellently copy pages of a book, stamps, or small pictures. Care, however, is recommended in portraiture, as perspective may easily appear distorted in this case.

The effect of the Focar lenses is that they shorten the focal length: this permits the camera to be brought much nearer the subject. Thus the subject is reproduced on a much bigger scale.

With the Voigtldnder Focar lenses you have three close-up ranges at your disposal, viz:

FOCAR 1 (1.25 Diopters) from 2' 71/2" to 1' 5 1/2"

FOCAR 2 (2.25 Diopters) from 1' 5' 1/2" to 1' 

FOCARS 1 and 2 combined (3.5 Diopters).... from 11'/4" to 8'/4"

HOW TO USE THE FOCAR LENSES:
With close-ups the viewfinder image does no longer correspond to the area reproduced, but is shifted upwards and to the left (parallax - see ill. below). With the FOCAR 1 the difference is up to 1/8, with the FOCAR 2 up to 1/4, and with the FOCARS 1 and 2 combined up to 1/2, of the viewfinder area.

 


APERTURE AND DEPTH OF FIELD
The iris diaphragm regulates the amount of light which reaches the film, and thus controls the exposure as well as the depth of field. Note that the aperture becomes smaller as the aperture number becomes larger, and vice-versa. Going from one number to the next, the exposure time required is always doubled or halved respectively. For example:

Aperture f/2 f/2.8 f/4  f/5.6  f/8 f/11 f/16
Exposure (e. g.) 1/500 1/250 1/100 1/50 1/25 1/10  1/5 second

The "depth of field" of a picture is that part of the photographed area which is still reproduced fully sharp in front of, and behind, the actual focused distance.

Note: Large aperture = small depth of field; small aperture = great depth of field.
You can read off the extent of the depth of field from the focusing scale and the depth of field indicator. The values of the unnumbered distance settings are shown in illustration (. After focusing the V mark points to the exact subject distance. Two series of aperture numbers are arranged symmetrically on either side of the mark. 
The depth of field then extends from the distance shown by the figure opposite the selected aperture number on the left to the distance opposite the identical aperture number on the right.

Picture Picture Picture

• For Example, if you have focused on 14 feet, the depth of field scale shows that at f/2 everything will be sharp from about 13 to 16 feet, at f/4 from about 12 to 20 feet, at f/5.6 from about 10 to 25 feet, at f/8 from about 9 to 30 feet, at f/11 from about 8 to 60 feet, and at f/16 from about 7 feet to 00 (infinity) T.

• To find the most suitable settings for aperture and distance for a given depth of field, set the limits of the sharp zone required opposite two equal aperture numbers. For instance, for a depth from about 7 to 30 feet, illustration ® shows that you have to stop down to f/11. The indicator then automatically shows the required distance setting.  

CARE OF CAMERA AND LENS
Successful work and long life of your camera depend largely on correct handling and careful treatment.
•   Do, please, handle it carefully and gently, and never use force. If anything should not go smoothly, it is much better to read again the relevant sections of this booklet.
•   Before loading the camera, clean off any dust that may have collected inside, with a soft brush.
•   At the seaside, or when there is a strong wind outdoors, carry the camera in its closed ever-ready case (beware sand); open case and camera only when making an exposure.
•   You must avoid finger prints on the lens because they spoil definition. The windows of the view- and rangefinder must also be kept clean, otherwise you will find it difficult to focus correctly.
• The lens is coated even on the outer surfaces (anti-reflection layer). It may be cleaned with a very soft brush, or a piece of soft, clean, linen. Grease spots may be removed by gentle dabbing with a wad of cotton wool moistened in medicinal alcohol or ether.
