TTIE NETTAR AIVD TTIE IKONTA CAMERAS
The Nettar and the lkonta are roll film cameras of the
folding tlpe, fitted with a variety of lenses and shutters and
taking di-fferent picture sizes. They are d_esigned to suit the
diverie requirements in dimensions, performance and price
of the amateur photographer. -at It should be stated this stage that lkonta models are
numerous and widely varied. They include, in addition to
the simple roll film cameras dealt with in this guide, more
advanced models with built-in rangefinder, and miniature
cameras for 35 mm. film. These are the subject of separate
Camera Guides.
Both the Nettar and the lkonta have been produced over
a period of almost twenty years. They have in th.e course of
tiine undergone changei in construction and been fitted
with improvements. An)r significant change in the develo.p-
ment oi these camera models is covered in this guide,
though minor alterations which are of no material con-
sequence, may not always be listed.
The two cameras were constructed with particular regard
to simple and quick handling and ability to stand up to hard
wear. Yet they are of the smallest possible dimensions
consistent with full efticiency.
The Nettars
Basically, the Nettar is a standard roll film model equipped
with a rairge of lenses from the inexpensive to the medium
priced, and fitted with appropriate shutters.

with leather bellows to the self-erecting front. Focusing is done by
means of the front cell. The camera is also fitted with a brilliant reflect-
ing finder and direct vision frame finder, and is covered in black
teitherette. The early model (Code 51012), was fitted with an f 7.7
Nettar lens in a 2-sp'eed shutter, with or without built-in delayedaction release. {View original page 6Page 7 · Read text

of this were without body release. Later ones had this addition, but
a!l were fitted with faster lenses and speedier shutter, namely the Nettar
f 6.3, f 4.5, or f 3.5, or Tessar f 4.5 in Derval, Klio, Telma, or Compur
shutters.
The early post-war camera,s were equipped with Vario, Pronto, or
Prontor S shutters.
In 1952 this type was redesigned and marketed as the Nettar ll. lt
was more streamlined, had an optical direct vision finder built into the
camera body (Code 517l2l, and a Novar f 6.3, or f 4.5 in Vario, Pronto,
or Prontor SV shutter was fitted as well as a depth of field indicator.
2. THE lf x 2f in. NETTAR takes 16 exposures on standard 120 size
film and has similar specifications to the 2f x 3i in. model, but is with-
rt out brilf iant-reflecting finder. The early model (Code 510) was fitted
with a Nettar f 6.3 in a Derval shutter. lts successor (Code 515) was of
t nearly identical design but fitted with the f 4.5 Nettar in a Klio shutter, first without, later with, built-in body release. This model has not been
re-introduced since the end of the war.
3. THE 2l x 2! in. NETTAR was first introduced towards the end of
f 938 (Code 5l5ll6), and was designed for 12 exPosures on_standard 120
film. lt is of the same design as the l$ x 2f in. Nettar (Code 515) and
fitted with a Nettar f 6.3 or f 4.5 in a Telma or Klio shutter. Early post-
war models were equipped with Vario, Pronto, or Prontor S shutters.
rl In 1952 the redeiigned 2f, x 2f in. Nettar was introduced on the market as the Nettar ll (Code 517ll6l. This was more streamlined, with
an optical direct vision finder built in, and fitted with a NovarF6.1 9f

The latest development in improving qhe pglfgrmance of a
photographic lens is a process Senerally-called coating or
bloom'ing. lt consists of the application of a microscopically
fine film- of some inorganic substance on the glass sur-
faces, which considerably reduces the light reflection
between glass and air surfaces in the lens. gain will be -The ar fully appriciated if it is understood that, for example, in
Teslar'f 4.5 the loss of light due to surface reflection is in
the region of about 35 per _cent.' a figure wh-ich can be reducei by coating to about 5 per cent. Apart from a gain
in the spebd of the lens which may be in actual Practice 50
per cent. (half a stop), its main importance lies in the elimina-
iion of thi scatter bi llght which impairs the contrast of the
image. This results in-a more brill'iant negative'.especially
' in t[e shadow regions where the tones are most subdued and so brilliance andcontrast are most needed. The post-war
lkonta and Nettar models have factory-coated lenses. With
older cameras the coating, however, can be undertakel by
retiable optical manufactuiers through photographic dealers.
The fact ihat a lens has been coated can be recognized by
observing in the lens reflections of, let us_say'.a l.TP'which
appear dlstinctly- coloured, as a rule a rather deep blue with
a'dinge of red. In the can of factory-coated lenses, a code
mark] the letter "T" in red, is stamped next to the lens
number.
The treatment and care of lenses is a matter of impoftance.
On account of its chemical composition, oPtical glass of
high quality is susceptible to the influence of moisture, and

be avoided. Since complete'cleanedprotection is impossible, the lens surface should be occasionally with a clean,

Also fitted were a number of shutters which are now
discontinued. They include:
THE DERVAL shutter. lt is used in the Nettar and Baby lkonta,

To'use the shutter, set the pointer on top of the shutter to one of
it- the numbers engraved there-25, 50, 1OO-which stand for fractions of seconds and should therefore be read as l/25, l/50, l/100 sec. On
pressing the release lever-or the cable release which may be screwed
bn to the cable release nipple below the release lever-the shutter
opens for the time set.
Ii Short time exposures are obtained by setting the pointer to B. Pressure on the release lever or cable release opens the shutter which closes
i again as soon as the pressure is removed.
Long time exposures are made by setting the pointer to T. By pressing
the release lever or cable release the shutter opens and remains oPen
until a second pressure closes it. t THE TELMA shutter. This is used in the Baby lkonta, l$ x 2f, in., the 2{ x 2} in., 2[ x 3tin.,2t x 4] in. lkontas and the Nettars. lt
has speeds oI 1125, l/50, l/100 sec., T and B settings, and is fitted with
a buiit-in delayed action release. The latest type of Telma shutter has
also l/ 125 sec.
The shutter is operated in the same manner as the Derval shutter
above. When using the delayed action release (which only works with
the instantaneous speeds l/25 to l/100 sec.), set the shutter speed in
the ordinary wayt then press down the delayed action lever on the
right of the shutter (the lever with a #d dot). Pressing the shutter
release sets the escapement in motion, and after l2 sec. automaticall)t
releases the shutter. The delay allows the photographer to take his
place-THE in the picture KLIO shutter is fitted to 2{ x 2} in., 2t x 3i in. and 2[ x 4[in.

f /f 00, lll75 (lll50) sec., T and B settings, and also a built-in delayed
action.
It is operated as the Derval (see above) but requires cocking by turning
the cocking lever on top of the shutter anti-clockwise until it engages.
The delayed action release can be used for all instantaneous speeds from
I to l/175 sec. and is manipulated as described for the Telma shutter
(above).
THE COMPUR shutter is used in some Nettar and lkonta models.
The small size Compur 00, as used in l$ x 2i in. and 2[ x 2[ in.
models has the speeds l, | 12, l/5, l/10, | 125, | 150, | 1100, and l/300 sec.,

Th6 handling of this shutter is the same as described for the Synchro-
Compur model (p. l6).
Viewfinders
The present models of the lkonta and the Nettar are fitted with
built-in, direct vision optical viewfinders. Earlier models haveafolding'
type finder which sprihgs automatically into position on opening the
camera.
Alternatively, the front frame should be pulled towards the front of
the camera, when the back sight will spring into position.
In cameras with mask for two picture sizes, the finder also carries
a mask which has to be lifted up io reduce the field of the finder for
pictures' Brilliontof Finder:half size.Some early models of the Nettar and the lkonta have
also been fitted with a brilliant finder, a reflecting finder fixed to the
shutter holder, which is used at waist level. Looking down into this
finder one sees a brilliant image, upright, but laterally reversed. The
finder can be turned through-9o" ind- can therefore be used also for
the horizontal camera position. The top of the finder shows a square
with a small blocked-out square in each corner. For horizontal photo-
graphs only the horizontal rectangle excluding the blocked-out corners
is uied, while for vertical photogiaphs only the corresponding upright
image counts.
Liter models of the Nettar and lkonta are not fitted with a brilliant
finder but carry a finder support on the top right-han-d side of the lens
holder, into wliich a detachbble reflecting finder may be inserted.
The latest versions of these cameras, with the built-in oPtical finder,
have no provision for a brilliant finder, with the excePtion of the l$ x
2*- in. lkonta. Atbodo Finder: This is an optical viewfinder built into some earlier
lkonta models, in which the actual field covered by the camera is
indicated by a white boundary line which seems to-be iustas far.away
as the subi6ct. As some part-of the surroundings of the field to be in-
cluded on the negative-outside the boundarf line-remains visible
through the finder] it is possible to keep an eye on these surround.ings
at the- same time. Thii is of particuiar vaiue when photographing
moving subjects.
The-actuil handting of the finder is the same as described previously
for the direct vision finder.
tn cameras with mask for two picture sizes, the finder also carries
a mask which has to be lifted up to reduce the field of the finder for
18 pictures of half-size.

Rangefinder for Nettar and Ikonta 1i
As guess work in estimating distances is unsatisfactory, t
.:1particularly with wide apertures, and the use of a taPe
measure is generally quite impracticable, a separate range- i
finder has been made available. This is constructed on the
"coincidence" principle. On one side of the square tube is
the viewing aperture fitted with an eye-cuP. Behind this
(within the tube) is a semi transparent silvered mirror at
an angle of45o, and at the other end ofthe tube a reflecting
prism which can be tilted relatively to the fixed mirror by
means of a cam mechanism attached to the calibrating
focusing disc. Setting the index to infinity (o) and looking
through the viewing aperture one perceives in the middle of
the circular field of view a smaller and lighter circle, and in
this a double image of a near object whose distance from
the camera is to be ascertained. By simply turning the
graduated disc the two images may be made to suPer-
impose so that coincidence is so perfect that only one image,
instead of the previous double image, is visible. By means of

HANDTING
Ioading
Loading of film into the camera is best done in subdued
daylight, i.e. in one's own shadow.
t. Open camera back.
2. Insert empty spool in chamber on winding
key side.
3. Insert rollfilm in other empty chamber.
4. Fix paper end on to empty spool.
5. Wind film transport key two turns.

the end with the slot, while the other end is received by the peg on
the opposite side of the chamber. The peg is on a spring plate which
has to be pulled slightly outwards to allow the spool to drop into
position.
The procedure with the V.P. film of the Boby lkonto is the same
except that the round end of the spool is first pushed over the spring
stud opposite the winding key. Then push the spool down so
that the bar of the key entages as far as possible into the slot, and
turn the key until it catches the spool with a click and turns it.
3. Place the full roll of film into the chamber opposite the one with
the film key by pulling out the side pin on its spring to allow the
spool core to enter and then replace the pin in the central bore of
the core itself. The pointed end of the backing paper on the spool
must point towards the empty take-up spool.
The procedure with the Baby lkonta is the same, except that the
spool is pressed over the spring stud and pushed down to engage
the opposite end on the second stud of the chamber.
4. Now break the gummed paper slip holding down the backing paper
of the full spool and remove as far as possible. Draw the pointed
end of the backing paper across the film aperture and fit into the
longer slit in the core of the empty spool. The black inner side of the
bac"king paper must face the ca'nr6ra lens. 2lView original page 23Page 24 · Read text

5. By turning the film winding key twice in a clockwise direction thc
backing paper is pulled taut. The paper has to lie flat between the
flanges of the empty spool and must on no account chafe or rub them.
lf the paper does not lie flat and straight, it must be adjusted.
5. Close the back of the camera and check by trying to pull it open
without touching the catch.
7. Turn the film winding key until No. I appears in the red window on
the camera back. Where the window has a cover this must, of
course, be opened to allow observation. On models with two
windows, it is always the one farthest away from the film wind key
which is used for setting film to No. | (see p. 8).
Shooting
l. Open camera front.
2. Check that film has been transported.
3. Set distance.
4. Set aperture.
5. Set exposure time.
6. View the image.
7. Release.
8. Wind on fllm for next exposure.
9. Close camera.
t. Press the front-opening button to release the camera front, which
will spring into'proper taking position (hence the name "self-
erecting" camera). The camera should be tilted slightly forward
as it is opened. There is no need to retard the quick-opening tnov€-
ment by applying the hand as a brake (as some users do) to Prevent
the film from being sucked forward out of its focal plane. The camera
is fitted with bellows ventilation which prevents the film from being
pulled out of true when the camera is opened.
2. in the modern models with double exposure lock no special check
is required as the shutter cannot be released unless the film has
been wound on. When using an older model without this device it
is advisable to adhere strictl)' to the sequence of operatlons given
(see No.7, above). Then the film is always wound on after exPosure'
thus confusion and uncertainty will be avoided.
3. The distance is set by rotatins-the front cell of the lens, the scale of
focusing distances b6ing eng[ved on the outside of the lens front.
Turn the lens front until-the distance figure-representing the
distance from the back of the camera to the subiect to be photo-
graphed-comes to lie opposite the index mark fixed to the shutter
casing.
