PENTAFLEX AK16
OPERATION MANUAL
Translated from German
Good results are guaranteed to you if
you read the first recordings before
the start of your first recording and
have a test piece of film in the hand
of the device
The ak16
(Image 1) a recording camera for
16mm one or two-sided perforated
film, brings through 1hr system many
advantages and expansion
possibilities, which are for the
filmbericht, the scientist and the
amateur.
(2) with which a film exchange can be
made within a few seconds by the
change of the cassette. The cassette
(picture 3) carries the entire transport
mechanisms - with the exception of
the gripper - A sensing-lever-counting
device, which always shows the
remaining film quantity in meters and
/ or. It can be supplied with cassettes
with a film capture capacity of 30m,
60m or 120m.
The ak16
(Ref. 4) shows 1m standstill and in
the run a right-sided, parallar-free and
10-fold magnified matt screen image,
which allows very light and clear disevaluation of the image cut-out and
the image sharpness. The viewfinder
is in the receiving direction.
The sector diaphragm of the AK16
can be continuously adjusted (0closed) in the range of 0 degrees to
180 degrees. It is used mainly for
landing and take-offs, as well as in
conjunction with a sine rewinding
crankshaft.
Furthermore, different exposure times
can be achieved by changes in the
sector opening at the same recording
frequency. for example:
16 speed - sector opening 180
degree = 1/32 seconds
16 speed - sector opening 90 degree
= 1/64 seconds
The table as of the Camera rear gives
an impression of the table
AK16
Lenses (image 7), the following types
are available:
Original Jena wide angle lens 2.8 /
12.5mm
Original Jena standard lenses 1.4 /
25mm
Original Jena telephoto lenses 1.4 /
50mm
Original Jena telephoto lens 2.8 /
80mm
Original Jena telephoto lens 4.0 /
135mm
The first 3 lenses are called standard
objective ones. All lenses have a
depth-of-field scale and are equipped
with anti-reflective coating.
The Ak16
The drive is fitted with a batterydriven battery motor (Fig. 8) that can
be attached to the side or from below
with a bayonet mount. The speeds
are 12,16,20,24 and 32 images / sec.
The running accuracy is plus or
minus 5% despite the voltage
fluctuations between 10.8 and 13
volts. The operating switch is
designed as a pressure switch, which
can be locked in the working position
by sliding in the direction of the
camera as a continuous-action
switch.
When the engine is switched off, the
gearbox and thus also the mirror
diaphragm is automatically set so that
the image can be viewed in the
search beam path. The switch-off
process is thus reduced to max. 2
images limited.
A tipping-resistant lead-over for 12
volt 10amp. Used with a battery
charge at 24 frames / sec. About
2400m film.
The AK16
Offers expansion options for a wide
variety of special areas, such as
hardly any other camera.
Accessories for:
Image frequencies from 3 to 96 F/per

Can be readily applied.
Synchronous coupling with other belt
loops (eg with a magnetic sound
device) is also possible. When the
second drive point of the camera is
coupled to the tape device by a
flexible shaft or by a toothed drive.
Filming in
In the 30meter cassette (picture 3
and 9) do not take place in a bright
sun.
After turning the locking lever (1)
upwards and forwards, the cover (2)
is lifted off.
The empty coil (4) lying in the
cassette (3) is pulled out. From the
full spool (5) about 60cm of film are
unrolled. The counter clock button (6)
is pulled to the right and thus the
space for the insertion of the full coil
is released. Unroll the unrolled end to
the bottom right. When the free end is
finished, the embossed layer scheme
is used.
For this purpose, the two pressure
pads (7) are pressed against one
another by light pressure until they
engage. As a result, the two tooth
drums (8) are released for inserting
the film. At the same time, the
toothed disc (9) of the counterplatform (10) is moved to the right
with simultaneous pivoting inwards
until it engages. When inserting the
film, the perforation must be pushed
into the teeth. By pushing the two
knobs (11), the runners (7) rest
against the tooth drums and
guarantee a firm fit of the film
perforation in the teeth. The counter
platform (10) is pivoted outwards into
the working position with one finger.
With slight fingertip pressure on the
detent button (13), at the same time,
(14), the correct loop size (picture 10)
is set, whereby it must be noted that
the stop pin penetrates through the
perforation and becomes visible in
the hole (15).
The resulting film creep below the full
reel may be somewhat smaller but in
no case larger than in the diagram.
The free end of the film is placed
around the lower deflection roller
(16), guided through the guide rollers
(17) and (18) and fixed on the core of
the empty coil (4). This small coil is
rotated clockwise until the exposed
film is under tension. After the cover
is put on and locked, the cassette is
ready for recording. In order to avoid
damage to the film, as well as
protection from dust and light, it is
recommended to slide the protective
cap (pict. 11) over the cassette neck
to prevent the film from being placed
in the storage space of the cassette.
This film insertion rule is valid for both
cassettes. However, it is to be noted
that daylight coils can only be used in
the 30 m cassette. For the 60m
cassette, the film storage space is
designed in such a way that only
unconsolidated film can be used as a
darkroom filling on the artificial core
known under DIN 15631.
scope of application
The 30m rewinding cassette
Fade-over and fade-out, with a 30m
rewinding cassette in combination
with the Ak 16 is possible.
This rewinding operation can be
performed by hand. I. With the aid of
a manual crank which can be
screwed to the motor coupling
position, as well as by means of an
intermediate transmission. When a
hand crank is used, a crank rotation
in the direction of the arrow
corresponds to the back rotation of an
image
When the camera is rewound, there
is a slight imagery shift. If an
exposure of the film is not desired
during rewinding, the lens must be
covered before the start.
To insert the F1. Mes in the 30m and
60m rewind cassettes are subject to
the same instructions. The cassettes
are marked with an R on the back.
Unlike the 30m cassette, the opposite
stage (10) is not swiveled inwards,
but remains in a fixed position. The
film is inserted into the film channel
between the opposite stage and the
cassette edge (figure 10)
Maintenance and Care
The filling channel of the cassette
must be cleaned from the time of film
dust deposits. For this purpose, the
counter-platform (Fig. 10, No. 10) can
be withdrawn at the lock (Fig. 10 No.
10a) after unlocking. Above all, the
plush strips used for light sealing are
to be cleaned and brushed.
Operational readiness of the camera
To insert the cartridge (fig. 12), the
handle (19) is turned to "A" with its
white marking. This means that the
gripper moves out of the movie
theater, the transmission is locked
and the cassette locking lever moves
into the "open" position. The
protective cap (fig. 11) is pulled from
the cassette neck, the cassette neck
is inserted into the shaft until the
cassette with the horizontal sliding
surfaces sits on the frame (20),
pressed slightly downwards by the
hand - and by turning the handle (19
). The locking device must be
actuated quickly and the
Push the cassette about 5mm
forward without removing it from the
chess frame.
After the end of this rotation, the
handle (19) is turned towards the "Z"
by its white marking.
Of the three lenses used in the turret
head, the upper one is in the working
position. If another lens is to be
shifted into the beam path. The snap
button (Fig. 6 no. 21) must be
pressed briefly and at the same time
the turret head must be swung until it
clicks into place. Of the lens
assembly, the 2 locking levers
belonging to the lens (Fig. 6 No.22)
must be pressed simultaneously to
the center of the lens.
This releases the lens and can be
removed (Fig. 5). When inserting, it is
important to note that the lens nose
and the glare drive are plugged into
the corresponding receptacles. The
easiest way to do this is when the
aperture of the lens and the lens
mount are rotated to Ansohlag. With
the 12.5mm lens a vignetting occurs
when the 135mm lens sits at the
same time on the revolver head. The
viewfinder eyepiece (fig. 13 no. 23)
must be adjusted in such a way that
the matt disc grain can be seen with
the greatest sharpness. Using the
plus or minus dioptric adjustable
eyepieces, the spectacle wearer can
adjust this setting to suit the eye and
fix it with the help of the conter ring.
The sharpness of the film image is
fundamentally controlled by the mirror
reflex detector, only second lens
should be used. In the case of
distance mea- surement, the film
must be of the same size (Fig. 5 No.
24).
The drive motor (Fig. 13) is removed
as a tripod camera, or from below,
after removing the protective cap on
the motor connection at the side of
the housing
Used as a handle of the hand-held
camera. Condition is that the red
point on the camera is opposite to
that of the motor, and that the motor
is pressed into the bayonet and
turned to the right until it snaps into
place. The clutch motor axle camera
axis is automatically found. (When
removing the motor, pull the motor
knob (fig. 13 no. 25) away from the
camera and turn it to the left at the
same time, after inserting the filled
cassette (Fig. 8 nr.26).
The AK 16
(30) cassettes (31) are fitted with a
gear box (35), the high-performance
motor with gearbox (27), the spring
mechanism (28), the single image
switch (29) , 3 filters (32), the drive
cable (33) and 2 additional lenses
(34). The suitcase is covered with
black artificial leather and has a red
effect on the inside
Maintenance and care suggestions
The camera, engine and cassette
oiling is required by the manufacturer
or the authorized repair shops after
50 operating hours. The camera drive
is provided with non-resinous, lowviscosity, cold-resistant oil. For this, a
few drops are sufficient.
The optics of the search beam, the
mirror and the lenses in the turret
must be checked for cleanliness
before each shot. When cleaning the
dust, gently clean the glasses with a
soft hairbrush.
The film channel in the cassette must
be cleaned of the film dust deposits
after each shot. Likewise, the image
slider in the camera must be cleaned
with a soft cloth or brush after each
run. Due to its construction, further
maintenance of the camera is not
necessary.
Accumulator (battery)
Is particularly important to disconnect
the plug from the mains before
starting up and recharge the battery
with pure battery acid-specific weight
1.28 = 32degree Beaums to approx.
0.5cm over the mark Saurestand
max. In this condition, leave the
battery to stand for about 3 hours,
then replenish the plates after the
suction cup (if the water level drops).
Then connect the battery to the DC
source, connect the positive pole of
the line to the positive pole of the
battery and the negative pole to the
negative pole.
The charging current should be 1
amp. Not exceed. Ladedaur about 15
hours charge is terminated when the
battery has reached a voltage of
approx. 15-16 volt under current. This
is about 2.5 to 2.6 volts per cell. After
the current has been switched off, the
superfluous acid has to be peeled off
to the mark. Screw on the battery,
siphon the battery of acid residues
and lightly polish the pole rests.
Charging: The weider charging is like
the start-up. Liquid lost by
evaporation (electolytics) must be
replenished by refilling of distilled
water. After the end of the charge,
remove excess acid as indicated
above. The acid level must not fall
below the mark.
All the 2-volts are to be tested for
equal stress, likewise the density of
the acid with the acid compound
added is uniform
(Figure 15). If cells are under the
voltage individually, these
rechargeable batteries or
rechargeable batteries must be
adjusted. The acid density of the
charged battery has 1.28 spec.
Weight = 32 degrees beaume. At
discharge, the voltage has dropped to
1.8 volt. When not used, it should be
noted that charging must take place
every 6 weeks. The plates must be
constantly under acid.
