Clje moJt imp opt ant point
of the whole booklet of instructions is on this page: You are requested to read
the instructions carefully, and to ma ke yourself familiar with the man ipulation
of your camera before you startt9k ing photographs or investigate its mechanical
construction.
We suggest that you practice the operating of the camera, as shown in Section 1,
without loading if. Having thus gained some experience, read on to get a
complete impression, and only then load your first film.
You should always bear in mind that the PROMINENT is a mechanical precision
instrument which must be handled with feeling and understanding. It will repay
your care with an endless number of beautiful and wonderfully sharp pictures.

apply only
to the standard 50 mm. lenses, i. e. the ULTRON 1/2 and
the NOKTON 1/1.5.
The TELOMAR f 5.5/ 100 mm.
telephoto lens with reflex housing is supplied with a special
6
instruction booklet.
Changing the Lenses
The quick-change mount allows rapid changing of all lenses.
For removing simply pull the catch of the bayonet lock
forward (left), turn the lens by abt. 45 degrees to the left or
the right and lift it out.
When inserting turn the lens until the catch engages wifh a
click. With the lens correctly in position, the catch must show
downwards. When changing lenses proceed gently; never
use force!
Stops and Shutter Speeds
The aperture (or stop) of the iris diaphragm controls Ihe
amount of light falling on the film, and thus the exposure.
It also controls the depth of field (see p. 26).
The slated speed of the lens (e. g. 112 with the ULTRON, f/ l.S
with the NOKTON), is always the largest lens apertur~ . Each
successive setting on
the aperture scale approximately
halves the light Iransmitted by the lens.
Therefore every
aperture number requires double or half Ihe exposure of Ihe
preceding or following aperture respectively. For instance:

Turn the shutter speed ring until the selected speed is opposite the
index line on the lens mount. The figure 1 stands for 1 second, all
other figures are fractions of a second . The shutter can be set to any
intermediate speeds, exce pt between 1/10 and 1(", or between 1(,,, and

makes the winding knob a littl e
harder to turn. It is th e refore advisable at this speed to tension th e
shutter directly with the tensioning
lever. Push the lever to the left
towards the red dot w ith your finger
as for as it wi ll go. But rem ember
also to wind the winding knob
through a full turn as far as it will
go. You will feel a slight resistance
while doing so .
Focusing with the Rangefinder
The combined view- and rangefinder is coup led with the lens . On
looking through it, you will see a bright circle in the cen tre of the
view. When the rangefinder is not correctly focused the subiect appears
as a double image wit hin this circle. Turn the focusing knob of the
rongefinder uAtil the two images coincide. The lens is then accurately
focused on the subiect. Alternative ly, set the distance by the scale on
the focusing knob.
Snapshots at f/ 8
These are easy even without the
rangefinder. Simp ly use the twopoint settings on the focusing knob:
Sel to 'V ~ 11 feet, and everything
belween 8 and 16 feet

Set 10 0
33 feet, and everything
will be sharp from 16

Slow Speeds
Instantaneous Exposures
When taking the picture, hold the camera as shown above.
Press it firmly against the face to keep il steady during the
exposure. Keep the eye close behind the eyepiece of the
view- and rangefinder so that you can see all four corners
of the image at once.
Hold your breath while exposing, and gently press the
10 release down as far as it will go. Take care not to jerk it.
To shoot without a rest al
speeds slower than 1/ 25 second, e. g. 1/ 10, 1/ 5, lh, and
possibly even 1 second, you
need a very sleady hand, or
some support for Ihe arms and
body.
A useful trick 10 reduce the risk
of camera shake with shots of
static subjects, e. g. interiors,
is to use the self-timer which
normally serves for taking pictures of yourself.
Tension the shutter in the usuol
way, set Ihe shutter speed, and
startlhe self-timer as described
on Ihe next page. After aboul
10 seconds the shutter will
release itself without any shake.
But do not move the camera
until you have heard the shutter
close wilh an audible click.
The Double Exposure Lock
This au tomatic devi ce prevents
double exposu res and blank
frames.
After the e xposure, the release
button is locked un ti l the film
is w ound on; the film transport
is then lock ed unt i l the next
time you p ress the release .
The Film Release
Time Exposures
over 1 Second
Set the shutter to B. Preferably
use a cable release with locking
screw. The release wil l screw into
the socket behind the body release . The camera must be firm ly
fixed for such shots; the best way
is to mount it on a tripod.
The Self-Timer
When the shutter is tensioned, the
tension in!') lever is next to the red
dot. Pu ll ing it further still as far
as it will go, au tamatica ll y bri ngs
a de lay mechanism into action,
which opens the shutter about
10 secands after re lease. Note :
Da not use the self·timer with the
shutter set to B or ta 1/". secand.
This is needed mainly when
loading the camera or w hen
changing partly exposed films .
A short pressure releases the
film transport fo r one frame.
Continuous pressure releases
the fil m tran sport whil e t he
pres sure lasts. Do not use the
fi lm release when rewinding
the film .
11
Films
The camera uses perforated
miniature film available in
daylight cartridges for 36 exposures 24 X 36 mm.
With
colour film the number of exposures varies with different
makes. Avoid handling the
film cartridge in very bright
light, preferably load and unload the camera in the shade
the shadow of your own
body will do.
The film indicator is provided
to help your memory; choose
a colour code for your films,
and set the indicator straight
12 after loading.
Opening the Camera Back
Press together both latches
and open the hinged back.
When
closing
the
camera
again, make sure both latches engage properly.
The Rewind Key
To pull up the rewind key
when loading the camera,
push the small button on top
in the direction of the arrow,
to make the handle spring up.
Then pull out as far as it
will go.

Inserting the Cartridge
The protruding spool knob
of the cartridge must fit into
the peg at the bottom of the
camera. Then push back the
rewind key
turning it
slightly if necessary, and fold
14 down the handle.
Turn the Take-up Spool
by the winding knob until the longer of the two slots for the film points
sideways. If the winding knob is locked, press the film release.
Thread the film end over the film guides and push well into the long
slot of the take-up spool (arrow, centre picture). It is advisable to fold
sharply the tapered film end by about
'I.
inch towards the emulsion
side before in order to make sure the taking up.
Turn the Winding Knob
Setting the Film Counter
unti l the full w idth of the film lies
over the transport shaft and both
sprockets engage the perforat io n.
Pay atten ti on that the fi lm is running exactly o ver t he sl ide guide
and is winding well.
Turn the winding knob until it locks (if not already locked).
Then pull it up, and turn the counting disc underneath to set
the leller F opposite the index mark. Push the winding knob
back again, turning it slightly, if necessary, so that it fits
snugly on top of the counting disc. Press the film release
once, and turn the winding knob until it locks. Repeat this
once more. The index mark now points to No.1 and the
t5
film is ready for the first exposure.
Now close the camera back.
Partly exposed films
are easily changed at any time
(e. g. black"and-white against
colour). Rewind the partly exposed film as described, but
make a note of the last number on the film counter.
Rewinding the Exposed Film
16
After the last exposure lift up the handle of the rewind key, but do not
pullout the rewind key itself (see illustr. left). Depress th e rewind button
and keep it depressed while turning the rewind key in the direclion of
the engraved arrow (see illustr. right).
While rewinding the film, watch the slotted end of the film transport
shaft turning in the base of the camera. When it ceases to turn, the film
is fully rewound in its cartridge. Release the rewin.d button, and pull out
the rewind key by its handle. Finally open the camera back and take
out the cartridge.
When loading a partly exposed film, proceed in the
usual way up to selling the
film counter to No.1. Then
press the film release, and
keep it pressed down while
turning the winding knob until
the film counter indicates one
number higher than the previously noted number. Now
finish exposing the film in the
norma! way.
Synchronised Flash Shots
The
SYN CH RO-.COM PU R
shutter makes it possible to
take action shots with flash
at the fastest shutter speeds
up to
1/ 500
second. The flash
can be employed either by
itself, or combined with daylight or any other light. It is
particularly useful for lighting
up
the
shadow
areas
in
against-the-light shots.
All makes of flash units
flash guns as well as electronic flash -
can be used with
the Synchro-Compur shutter..
Connecting the flash unit to the camera:
First fix the camera to the bracket with a tripod screw (left) . The flash
unit should be to the left of the camera so as to allow free access to
the body release and winding knob. Some light-weight flash guns can
be fixed directly to the detachable accessory shoe (page 24).
Then connect the special synchronising cable to the flash unit and push
the plug over the tip of the shutter (right).
17
Setting the SYNCHRO-COMPUR:
The flash should reach its peak brightness just when the
shutter is ful,ly 0'Pen. The synchronising-lever - and also
shutler speed and aperture - must therefore be set to suit
the type of flash in use.
Flash bulbs and electronic flash tubes differ in the time they
take 10 reach their 'Peak. They thus fall into several classes
as shown in the table opposite. Set the synchronising-lever
either to "X" or "M", according to the flash used (see illustration). Then set the shutler speed according to the values
shown in the table. Tension the ·shutter in the usual way, and
Ihecamera is ready for the flash shot. Look up the instruction leaflet enclosed with the flash bulbs or electronic
equipment for the correct lens apertures needed.
"X" Selling
The contact closes at the instant
when th e shutter is full y open.
"M" Selling
Flas:h shot's w ith self-timer are, only possible at the shutler
speeds indicated' under "X" in the table. The actual position
of the synchronising le·v er is 'imma·l erial as the "M" setting
18 does not work when you use t:he delayed action release.
The contact closes a short time correspondin g to th e firing delay of
cla ss "M" flash bulbs - before the
shutter is fully open.

Electrical Details:
The oui"er pole of the synchroniser tip is earthed to -the
shutter.
To avoid wiring up the leads
the wrong way round, get an
expert to connect the cable to
the flash gun Ihe first lime.
The flash con-tacl will carry the
fir ing current of all types of
eleclronic flash tubes. When
used with flashbulbs il' will
carry a temporary load up to
10 amps at 24 volts, thus allo w ing simultaneous firing of
several bulbs connected in
parallel. The longest pe rmissible exposure time in this
case is lito second.
Caution : The flash contact must not
be used to fire bulbs from 110 or
220 vo lt electr ic mains .

FOCUSING TABLE
Close-ups with Supplementary Lenses
Do not miss this highly interesting field of photography
wh ich so many amateurs seem to neglect. Large-scale
pictures of flowers, butterflies and other animals, small
"objets d'art " , etc. can yield extraordinarily beautiful
results . With the Voigtlander Focar lenses you can also
copy without trouble pages from books, stamps, or small
pictures. But be careful when using Focar lenses for portraiture as the pictures may easily show distorted perspective.
Distance
scale on
The Focar lenses shorten the focal length of the camera lens
and thus allow the camera to approach the subject much
closer, g iving a larger image .

Working with Focar Lenses:
•
Approach the subiect with your camera until
the image in the finder is of the desired
size. Then push an F 1 or F 2 Focar lens
w hicheve r covers the subiect distance over the camera lens mount .
Accurately measure the distance from the
front surface of the Focar to the centre of
the subiect. Look up this distance in the
second or third column of the table opposite. The first column then shows the required distance setting for the camera lens.
•
At full aperture the image is slightly unsharp, particularly towards the corners. The
definition improves on stopping down, and
reaches its usual standard at fill .
•
The Focar lenses have no effect on the expOlure time. Longer exposures are, of
course, necessary when stopping down.
The closer you approach the subiect the greater will be
the parallax error (difference between what the viewfinder shows and what will appear on the film) . See
table and illustration below.

Improve your shots with filters
Your Voigllander lens will satisfy your
most exacting demands on sharpness,
but you can greatly enhance the
mood or obtain special effects in
your pictures with Voigllander filters.
With a few exceptions, therefore, use
a filter for all outdoor shots whenever
possible. With filters the sky in particular -
with or without clouds -
will show up much more effectively.
Do without a filter only when you
need very short exposure times in
poor light, such as sports shots in dull
22
weather, or fog and mist subjects.
~ filters are made of spectroscopically
tested glass dyed in the mass. All surfaces are carefully polished and are absolutely parallel. All filters
are supplied in a push-on mount (47 mm. diameter for
the PROMINENT) and can be used together with a
Voigllander Focar lens or the lens hood or both.
~ Yellow Filter G 1
A light yellow filter recommended when only slight correction is desired, or where th e increase in exposure
I'ime required with Filter G 2 (medium yellow) cannot be given. - Fi lte r fa ctors (ex pos ure increase ): 1.5-2 times.
~Yellow Filter Gl
The "unive rsal f ilter" for a ll outdoor work . Particular ly suitab le to bring out c loud effects o n blue sky; fair hair,
ripe corn, spri ng and autumn foliage are given more brillance . Indispensable for snow pictures in sunsh ine. '
Facto rs: 2-3 times.
~ Orange Filter Or
A fi lter for special effects, Renders the blue of the sky rather dOl ker than natural, makes yel low and reddISh
colours stand out clea rl y. In distant views it reduces atmospheric mISt, thus bringing out detail. In ou tdoo,
portraits ii" suppresses certain sk in blemishes. -
,Factors 5-6 times.
~ Green Filter G r
for better reproduction of green in landscapes. When us ing certain panchromatic fi lms, highly sensiti ve to red,
th e act ion of green is promoted by subdueing the red, Consequently too pa le lips and too dark eyes are
avoided on portraits in artificial light. - Fa cto rs : 3-4 times .
~UVFilter
This filter is used in high altitudes (mountains) to suppress ultra violet rays which may cause unsharpness.
Wilh black and white material the delicate aerial perspective is fu ll y retained. Wi th co lo ur material it cou nteracts the much dis liked "b lue tinge' , securing warmer tones in general. - Facto rs : No exposure increase for
black and w hite ma terial . 1.5 times for colour material .
13
The Lens Hood
shields the lens against reflections
caused by direct light when shooting into the light and further increases the brilliance of the pictures. Th e hood wi ll fit the lens as
well as the 47 mm. Voigtlander
filters and Focar lenses or combi·
14 nations of the two.
The ~ V iew Finder "KO NTUR"
This finder is excellent for following fast moving subjects (sports, action
shots, etc.). It is ideal for photographers wea ring spectacles. Keep b oth
eyes open, while sighting the subject. The eye watching the subj ect
direc tl y will see it in its natural size and brightness, while the eye
looking into the finder w ill see the fram e outlining the subject. The
point in the finder shows the centre of th e field, wh ile a dotted line
indicates the parallax error wi th close-ups when setting from 3,3 to
6,6 feet
Note! Do not allow any direct sunlight 10 reach th e eyepiece of the
Kontur Finder.
The Ever-ready Case
for the PROMINENT is made of best quality hide, lined inside, and filled with a carrying and neck strap.
This case holds the camera even while taking pictures,
without affeeling its instant readiness for aelion, and has
many advantages:
•
When closed it shields the camera from the effeels of
bad weather, and in addition gives appreciable protection against damage through dropping or knocks .
•
The lid pivots in any direelion. With upright shots it
can not therefore swing accidentally in front of the lens.
25
Aperture and Depth of Field
The deplh of field of a pielure is Ihe pari of Ihe view in fronl of, and beh ind, Ihe focused
dislance which is slill reproduced sharply on Ihe film.
This deplh of field is, howeve r, nol constanl. II becomes gre aler, Ihe more Ihe lens is slopped
down, and it decreases Ihe larger the lens aperture used. So remember :
Large apertures (e. g. f/1.S or 2) produce little depth of field,
Small apertures (e. g. f/ 8 or 11) produce great depth of field .
You can read off Ihe depth of field (with 50 mm. lenses only) for each exposure from the
rangefinder focusing knob. When the rangefinder is sha rply focused, Ihe ... mark points to
the exael subjeel distance. The focus ing knob also carries fwo series of aperture numbers
symmelrically grouped 10 Ihe left and right of the dislance mark, with Ihe distance scale
immediately above. The depth of field always extends from the distance above the aperture
number chosen on the left to the distance above the corresponding aperture number on the
26 right. (The illustration above the seelion on Snapshots at 1/8 on page 9 show~ an example.)
Film Speeds
Fi lm sens itiv ities o r sp ee d s are d eterm i ned by the
ma kers in va ri ous w ays an d often measure d by
d ifferent systems. Th e tabl e on th e right gives a
rough compari son o f the more usual systems .
Films slower than 240 BS Log Index (20 ASA)
are ex tra fine grain fi lms of the highest reso lving power,
allowing very great enlargement. Th ey tend to be some·
what contras ty, and require accura te exposu re.
25-270 BS Log Index (25-40 ASA) Films
are bes;' for average subjects. They are fast and give fine
grain.
Films faster than 290 BS Log Index (64 ASA)
are high speed films for occas ions w hen the lig ht is poor
and the subject demands short exposures. Their high red
sensitivity makes them particular ly suitable for artificial
light photography. Their grain is, however, somewhat
coarser th an with other types of fi lm.
Re me mbe r : Every increase or dec rease of 30 BS Log Index
(doub le or ha lf the ASA Index number) halves or doubles
respective ly the exposure required.
