THE REGUIA CAIVIERA
Th9 Regula camera is a miniature camera producing a
negative lxl{ in. (24x36 mm.) on 35 mm. cine film.-A
single load g{ film in standard iassette will take up to 36
exposures.. The film can be loaded and unloaded in daylight.
The body of the. Regula. is a precision lightweight-die
casting covered with mould free dura-fabric.- Interlor and
outside trim are anodised. The top part of the housing,
shutter base plate and catches are brirsh chrome finishe?
to ensure permanent good appearance and to make the - camera climate proof. Eyeleds are provided for use of a
neck strap.
The dimensions of the Regula are 5x3tx2f in. The weight is 19 oz.
Lens and shutter are connected to the camera front by
arigidlyfixed tube, thus doingaway with opening and closin!
of the camera.
The Regula is fitted with a quick wind transport lever
o.n top of the instrument which tiansports the film, advances
the exposure counter and tensions the shutter simurtan-
eously with a single movement. An interlock mechanism
automatically prevents double exposures or blank frames.
The interlock mechanism is remarkable as releasing and
transport locking takes place simultaneously and n6t, as
is usually the case, as successive actions on releasing. A
bgdy shutter release and accessory shoe are on th6 top
p-late_. The automatic exposure counter is in the centre of
the. film transport lever ihowlng the number of exposures

Interchangeable L,enses
The Regula model lllD ls fitted wlth an interchangeable
lens mount to permit the use of short focus and long focal
length lenses.
To change lenses hold the camera body firmly in your left
hand, push the red lens locking lever which is on the top of
the large serrated lens ring forward and turn the lens in an
anti-clockwise direction by approximately 45' when it can
I be lifted awa)t. To replace a lens match up the red mark on
the locking lever to a similar red mark inside the shutter
frame. Now insert the lens gentl)r and turn it in a clockwise
direction, when it will click into place. Do not use force.
THE WIDE-ANGLE LENSES are the l* in. (28 mm.)
Regula-Ultra Lithagon F3.5, a six element lens with an
angf e of view of T6 compared with 50" of the standard lens,
thus showing a field over half as large again.
The l$ in. (35 mrn). Regula Lithagon F3.5, a four element
lens with an angle of view of 64 compared with the 50'
of the standard lens.
These wide-angle lenses have definite advantages in cases
where the practical distance between camera and subject is
limited and insufficient for the standard lens to record the
subject in its entirety. They are therefore primarily of use
for architectural photography and interiors. In view of their
short focal length the depth of field covered is particularly
wide even at full aperture. The 35 mm. Lithagon can be
employed with advantage as a 'quick shooting' lens for
general purposes where accurate focusing would be incon-
venient (e.g. owing to insufficient time). The Ultra Lithagon
is less suited for this latter purpose but has the advantage
of covering a wider angle. Both lenses are fully colour
corrected, free from vignetting, have a flat field, and are
coated.
THE LONG FOCUS LENSES are the 3{ in. (90 mm.)
Regula Ennalyt f3.5, a four element lens with an angle of view of 27o, giving a linear magnification of two times
compared with the standard lens (: four times field
magnification). 1lView original page 12Page 13 · Read text
The 5$ In. (135 mm.) Regula Ennalyt F3.5, a five element
lens with an angle of 19" giving a linear mangification of
three times compared with the standard lens (: nine times
field magnification).
These lenses are therefore particularly suitable for sub-
jects that are difficult to approach closely, such as animals
or children, architectural detail, sports events, etc. In
photographing distant views without near foreground they
bring the subject nearer; also permit a greater camera-to-
subject distance in portraiture, producing a more pleasing
perspective. At the same time the reduced depth of fielil
concentrates definition on the portrait, avoiding- distracting
sharp backgrounds.
Vieufinders for Interchangeable Regrula lrenses
While there are, at present, no special viewfinders
marketed by the manufacturer of the Regula for their ' alternative lenses, there are nevertheless a range of finders
on the market which show the correct field covered by the
various wide-angle a1d long focus lenses. Two groups of
finders are made, both designed to fit the accessory shoe on
top of the Regula. The individual type, generally tubular
finders for one particular focal length; the universal type of
view-finder which shows the corrett field for a numb6r of
different focal length lenses.
Coated Lenses
The Regula lenses are coared. This coating or blooming,
as it is sometimes called, consisrs of the application of a
microscopically fine coat of an inorganic substance on the
glass surface. This considerably reduces the light reflection
at glass-air surfaces in the lens. The gain will be fully ap-
preciated if it is understood that in a lens like the Tessar,
t.he loss of light due to surface reflection is in the region of
. _ 40 per cent and can be reduced by coating to about 5 per12 cent.
www.butkus.usView original page 13Page 15 · Read text
,
Ap?rt from a gain in the speed of the lens, which may in
actual practice be nearly 50 ier cent (half a stop), the rfiain
importance of coating lies in the elimiriation of th'e scattered
light which impairs the contrast of the image. This results
in a more brilliant negative, especially in the-shadow regions
where the tones are most sribdued and so brilliance'and
contrast are most needed.
The Care of Lenses
The treatment and care of lenses is a matter of importance. ll Due to its chemical composition, optical glass of high quality
! is susceptible to the influence of moistureiand for t[is re.toL
tt touching the glass with the fingers should be avoided. Since
complete protection is impossible, the lens surface should be tl$
cleaned occasionally with a clean, soft, chamois leather. lrt Fo.* coated lenses shoirld be cleaned with a fine camel-hail
lt brush gently used, or. by carefully wiping with a piece of cotton wool moistened with spirit.
The Lens Hood
This is a tube, as a rule made from metal, placed over the
front of the lens to protect it- from light coming from out-
side the actual picture area. There is n-o picture ihich could
not be improved in clarity and brilliance by the use of a
lens hood. The wider th6 aperture of the'lens the more : I important is the use of the hood.
otherwise light coming from obJects outside the actual
picture area will reach the lens anil give rise to scattered t
light by internal reflection which woulJ reduce the brilliance
of the picture considerably. This applies not onry to photo-
graphs taken against the-light-where the leni ho6d be_
comes indispensable-but also to sunshine in general, and
to a less extent, to pictures in diffused rieht ind indoors
(on account of reflectid light). The lens hoo"d can be used in
combination with filters lnd close-up lenses (see pages 63 t4 and 60).

The Shutters
The Regula employs the Prontor SVS shutter with. light
value scali, whit6 ebrlier models are equipped with the
earlier Prontor SVS, Prontor SV, Prontor S, or the Compur-
Rapid or Synchro-Compur shutters.
The shutter requires tensioning in the early Regula
cameras, before exposure, while those of the current series
are automatically tensioned on advancing the film with the
rapid winding l6ver. The shutter release of all models is
actuated by the easily accessible shutter release button on
the camera top plate.
All shutteri ire synchronized for flash photography; on
the Prontor SVS, SV, and Synchro-ComPur, the flash
synchronization can be adjusted to work even with fastest
speeds (see page 75).
THE PRONTOR SVS, SV AND S SF{UTTERS have eight
aspeeds: l,,12,l15,lll0, l/25, l/50, l/l00and l/3g0sec., and
ti setting for time exposures, as well as a built'in delayed
action release.
Operating the shutter requires these actions; settlng th.e
speed, tensioning the shutter (on the early Regula models),
and releasing it.
To set the shutter, turn the outside milled ring until
the red index mark on the rim points to the speed required.
The engraved figures l, 2, 5, 10, 25, 50, 100 and 300 stand
for, | , | 12, | 15, I ll0, l/25, l/50, l/ 100, and l/300 sec. resPect-
ively.
To tension the shutter, pull the tensioning lever, im-
mediately behind the milled setting ring, ant-i-clockwise
as far as it will go. On Regula cameras excePt the first models
the shutter islutomatically tensioned on transPorting the
film.
To release the shutter, Press the large protruding release
button gently downwards.
A deilyed'actlon release (also called self-timer) is. butlt
into the Prontor shutters which permlt the photographer to
appear in the photograph himself. To use the delayed action 15View original page 16Page 17 · Read text
release, set the camera in the usual way and mount lt on 6
rigid suppoft, preferably a tripod. On the Prontor SVS
set the.synch.ronizing lever to V; on the SV shutter press
down the delayed action setting lever as far as it wiil go.
This is the lever with a red doCin its centre on the lovier
p.art the shutter rim. On pressing the shutter release, -of the shutter opens after a delay of apploximately 8 seconds,
giving the photographer rime to talie his placd in the pic-
ture.
On the Prontor SV the synchronizing lever (see page 75)
must be set to X when th6 self-timer Is used.'
THE PRONTOR SVS WITH LIGHT VALUE SCALE fitted
l14, !1th.g.prelglt !.egul1 cameras has 9 speeds: l, l12, ll8, !/15, l/30, 1160, l/125 and 1i300 sec., as well'as a'B
setting.
LIGHT VALUES. On the side of the shutter rim a range of
numbers is engraved in red from 2 to 17 which repre-sent
light_ values for correct exposure. Each light value corres-
ponds to a range of shutter speed-apertuie combinations,
exposure but is covered by a lilgle setting. The built-in meter of the Regula lllB, Cita lll, and lllD is also calibrated
in light.values; the reading can thus be transferred directly
to the shutter.
To set the shutter to the measured light value, press in
the small serrated projection on the diaphragm ring and
hold it securely in this position. Then iotate the milled
shutter speed ring with the other hand until the required
light value on the red scale comes opposite the red tri-
angular mark.
It should be noted that_light values and stops may be set
to the intermediate half-way positions, bui not'shutter
speeds. This latter situation may arise if you reach the
beginning or.end of the aperrure scale while changing the
shutter speed, and must be avoided. The interval Setween
lll25 and l/300 sec. represents lf, stops.
To set the shutter speed and stop independently, wlthout
- _ uslng the llght value, depress the serrated proJectidn for both16 aperture and speed setting.

l LENSES AND SHUTTERS
The Cassar and Trinar (left) are three
component an:ufigmats and on current
Regula models both have a focal length of
lf in. (45 mm.) and a maximum aPerture

..Jh. Synchro-Compu!- and recent Compur-Rapid shutters differ only in their flash synchronization'(see pige 75).
Again three actions are necessary; setiing'th-e re{uired

sec. On the other hand no intermediate speeds between I
sec. and B nor between l/ l0 and | 125 or between l/250
and l/500 can be set.
When turning the outside milled ring of the shutter from
11250 to l/500 sec. a resistance is felt which is due to the
additional spring fitted to achieve this fastest speed.
FOR TIME EXPOSURES with any of the shutters described
set the shutter speed ring to B (brief time). The shutter of
the old Regula models requires tensioning in the usual
way. On releasing, the shutter will remain open as long as
the release button is pressed down and closes as soon as the
pressure on the release is removed. For such time exposures
the camera must be mounted on a firm support such as a
tripod. lt is safest to release the shutter with the help of
a cable release to avoid shaking the camera. This release
is screwed into the cable release socket of the shutter.
To give long time exposures-where the shutter is to
remain open for longer than one can conveniently keep
the release depressed-a cable release with locking screw
should be employed. To make the exposure set the shutter
to B, depress the cable release plunger, and tighten its
fixing screw. The shutter will now remain open until the
fixing screw is unlocked.

3. To set the film indicator on the rewind knob, turn the centre disc
until the appropriate speed in DIN or ASA is opposite the index
mark. In the case of daylight type colour film, turn to 'Color T;
for artificial light colour film, turn to'Colour K'. On camera models
with built-in photo-electric exposure meter-which have no film
type indicator-set the film speed on the meter. See p. 66.
4. Insert the cassette with the film into the empty chamber so that the
beginning of the film points towards the take-up spool.
5. Push back the rewind knob so that its pronged end engages in
the slotted hole of the cassette centre spool.
6. First, turn the take-up spool in the opposite chamber by its edge
until its slot lies uppermost. Then pull the film end icross the
picture aperture and fix it by pushing it into the slot.
7. Turn the take-up spool by its edge until the film pulls right. Only

position. Screw the tripod or the ball-and-socket head
into the tripod bush in the bottom plate of the Regula.
Carrying
However eleg-ant it may be to carry the camera on a long
strap la.nging from the shoulder, this position is quite
unsuitable for quick action. A better method is to cari-y it
on a short strap around the neck, so that it lies on the chbst.
Opening the case and lifting the camera up to the eye is then
a matter of seconds.
The ever-ready case carries the camera ready for use; it
does not have to be removed when taking the photograph.
