The Arriflex 16S/B-GS
[With 60-Cycle Generator and
Automatic Startmarker]
The 16S /B-GS is a special model of
the basic Arrilflex 16 S/B. It is factory
equipped with a 60-cycle generator, an
automatic startmarker and a manually
operated cue marker, designed to
work with all ¼” tape recorders
equipped with the pilotone system.
The 60-Cycle Signal Generator
A miniature generator is built into the
camera. When the camera runs at 24
fps, the generator ooutput is a 60-cycle
signal of approximately 1.2 volts. This
signal is the heart of all Piloton
synchronizing systems. The output
appears across pins 1 and 2 of the
camera’s 5-pin Tuchel outlet, after a
300 milli-second delay. Sync cables
are used to carry this signal to the tape
recorder. (See price list for various
types).
Automatic Clapstick
The 16 S/B-GS has an automatic startmarker capable of putting start-
marks on the film and on the tape, automatically, each time the camera is
started.

The miniature lamp, which is visible just over the camera hand grip is paired with
another lamp, located inside the camera. The inside lamp flashes whole frames
of film, during camera run-up time. The result is that the beginning of each take,
three or four frames of film are flashed. The start mark on the tape corresponds
with the point just past the last flashed frame on the film. Light from the interior
marking lamp in visible in the viewfinder, during run-up time. Note that the lamps
are activated only when a properly wired cable is plugged into the 5-pin Tuchel
outlet.
To remove the start marking lamps for
replacement, turn the plastic housing on
its metal base counterclockwise. The pair
of lamps are secured to the ends of the
black rod (P1) which may be lifted out.
These lamps are resistance matched
pairs, and must always be replaced with a
new, matched pair.
8 Volt DC Output
At the same time, during which the start mark lamps are energized, the camera
will supply 8 volts DC through pin 3 on the Tuchel outlet. (See schematic).
This voltage energizes a 1000 cycle oscillator built into the tape recorder. The
1000 cycle signal is recorded on the tape and serves as a start-mark in the
sound track. The oscillator is cut off simultaneously with the marking lamps in
the camera. Therefore, the point where the 100 cycle signal ends on the tape,
corresponds with the point where the flashed frames end on the film and
constitute the sync point.
Edge Marking System
The edge-marking lamp is mounted in the
base of the camera under the coin slotted
contact screw. The mating indicator lamp
for edge marking is located on top of the
small generator casting on the right side
of the camera. These lamps are also a
matched pair and should be replaced with
matched pairs.
At the start of a take, the edge-marking lamps work simultaneously with the full
frame marking lamps. However, these lamps mark the film at the edge only, and
the edge marking is displace on the film by about 3 ½ frames from the aperture in
direction of travel. The edge-marking lamp can be energized manually during a
take for event marks of various kinds.

Arriflex 16S
Operating Instructions

NOTE: Numbers in ( ) refer to callouts on front overleaf.
Holding the Camera
Place thumb of right hand between
contour grip (21) and side of camera,
while the other fingers reach forward
around the “bulge” so they are free to
actuate the follow-focus grips (38) and
diaphragm ring of the lens in taking
position. Place palm of left hand
around finder housing on left side of
camera, fingers over ON-OFF switch
this way, camera can be held steady
and comfortably.
When the “ON” switch (10) is pressed
down, it remains locked in the down-
position until the release lever (11) is
pushed in.
An accessory PISTOL GRIP WITH OR WITHOUT SHOULDER BRACE IS ALSO
AVAILABLE. It is attached to the tripod socket in the base of the camea and has
its own release trigger which activates a switch inside the tripod socket.

Viewing
Place eye against finder eyecup.
(Eyeglass wearers should remove or
raise glasses to forehead and sight
without them). For left eye viewing, the
eyecup can be rotated. A periscope
finder can be used for left eye viewing
when a magazine is attached to the
camera.
If viewing is obstructed by the closed
mirroe shutter, turn the inching knob (27)
on the motor to open the viewing system.
First focus your eye to the ground glass
or fiber screen by turning the knurled
diopter adjustment ring (5) at the
eyepiece until the grain structure of the
ground glass appears sharp. You best
do this without a lens in the turret socket. The adjustment ring (5) should then be
secured with the diopter lock ring (7). This setting need never be changed
unless other persons use the camera. Once proper finder focusing is obtained,
you can focus on a subject by actuating the focusing mount of the lens. For
critical sharpness, always focus the lens with its diaphragm wide open.
While the optical system of the finder is constructed so that it prevents light from
entering and fogging the film, the eyepiece must be shielded from direct
(horizontal) sunlight or powerful back light when the eye is removed from the
eyepiece. For this purpose a light cover (18) is provided inside the rubber
eyecup. During filming always press eye firmly against eyecup or close the cover
door (18) on the eyepiece. The automatic eyepiece, available as an option, will
close the reflex finder system anytime pressure against the eyecup is removed.

Detachable Eyepiece
The detachable eyepiece, the same on
all Arriflex cameras, permits the use of a
variety of finder accessories like the
PERISOPIC ACCESSORY FINDER,
WHICH FACILITATES VIEWING FROM
THE SIDE OR THE TOP (for instance if
camera is on a microscope or copy
stand), or viewing with the left eye when
a 400 ft. MAGAZINE is attached to the
camera. A finder extender can also be
mounted when working in unusual
situation.
To remove the eyepiece, turn the knurled chrome-plated collar (6) clockwise. To
re-mount it, first engage the keyed flange properly then turn the collar (6)
counterclockwise. Exercise care not to cross thread the collar and make sure the
eyepiece is flush against the finder flange.
The rubber eyecup swivels freely in its ball-stop bearing and can be pulled off for
cleaning. The installation of a prescription corrective lens –of 15.5mm diameter
–is possible in a specially provided recess in the eyecup assembly.
Ground Glasses/Fiber Screens
The standard ground glass, supplied with the camera, is marked to show: center
cross, TV safe action and camera aperture. It can be interchanged for a special
ground glass with center cross and projector aperture only, or for a clear glass
with reference reticle for cinemicroscopy. (See price list for details.) Such
installations must be done only by skilled, Arriflex trained technicians and require
special tools.

All 16 S cameras equipped with APEC have the new fiber screen in place of a
ground glass. The fiber screen has distinctly greater brilliance, which is
especially noticeable in low light conditions or at small lens apertures. Fiber
screens are available for later installation in any Arriflex 16S above serial number
8981. On Arriflex 16S cameras with Serial Number 6101 to 8980,
exchangeability of the ground glass to fiber screen is possible by using a finder
modernization kit (see price list for details).
The Three Lens Divergent Turret
The Arriflex 16 features a heavy-duty three-lens turret (37). The lenses are
mounted in a divergent manner of 21o to prevent optical and mechanical
interference between wide-angle and telephoto lenses.
A turret lock prevents the turret from being turned unintentionally. To lock the
turret, be sure the taking lens is precisely located by the turret detent
mechanism, then turn the lock lever clockwise as far as it will go. (See
illustration 6). To open the turret lock, turn th elever counterclockwise. Three
turret grips (47) make it easy to rotate the selected lens into taking position.
Always turn the turret by means of the grips, never by the lenses.
The back of each turret grip (47) is coded with either one, two or three dots.
These dots can be seen from the rear, while filming and can therefore be used to
indicate if the wide angle, normal or telephoto lens is in taking position.
Standard Lens Mounts
Two of the three lens cavities are for
standard Arriflex lens mounts. These
are ideal for fixed focal length lenses or
average size. To seat lenses in standard
Arri mounts: Press the pair of lens
locking levers (38) together, align the
keyway in the lens mount with the key in
the socket and carefully place the lens in
the socket. When the lents is seated,
release the lock levers, and check that
the lens is locked safely in place.
Always keep lens mount and lens socket
lubricated with a trace of the instrument
grease supplied with your camera.
To remove standard Arri mounted lenses: Press the lens locking levers (38)
together, then lift the lens straight out. Always keep empty lens cavities covered
with cavity caps.

Bayonet Lock Lens Mounts
One of the three lens sockets is for lenses in Bayonet Lock Mounts. This stronger
mount, is primarily intended for zoom lenses or other larger, heavier lenses.
To seat Bayonet Lock Lenses: Note the locking lugs at the rear of the lens mount
-position the lens so the lens data engravings are on the top, and the lugs are in
line with the keyways in the socket. (See illustration). Insert the lens as far as it
will go and then twist the entire lens clockwise by 15°. You will hear and feel the
mount latch into place. The lens locking levers (38) operate automatically in this
case and need not be depressed.
To remove Bayonet Lock Lenses: Press the Locking Levers (38) together, rotate
the lens counterclockwise. Then lift the lens out of the cavity.
Always try to hold the lens on a fixed part of the barrel. Don't rotate the lens for
mounting purposes by the focusing or iris rings. The Bayonet Lock mount
provides seating and lens alignment of superior precision and durability. Use
zoom lenses always in Arri Bayonet Lock Lens Mounts.
Lenses for Arriflex are made by the
world's leading optical manufacturers
and represent the ultimate in optical
and mechanical quality. Lenses
available for the Arriflex 16 range in
focal length from 5.7mm on up.
Standard lenses are equipped with
follow-focus grips (20) and most have
diaphragm click-stops. Use only
lenses in genuine Arriflex lens mounts
to insure trouble-free operation and
optimum image quality. For extremely
long or heavy lenses, lens support
systems of various types are
available, the most practical of which
is the standard ARRIFLEX bridge
plate system.

Standard Matte Box and
Filter Holder
To attach the matte box to the camera,
slide the end of the boom into the special
shoe (19) on the front of the camera
housing. Lock it into position by turning
the knurled (44) knob at the front of the
boom.
The rear stage of the matte box is
adjustable to accommodate lenses of
various lengths. The front is adjustable
for optimum protection from side light
and to prevent vignetting irrespective of
lens focal length.
SPECIAL EFFECT MATTES such as
key holes, binoculars, etc. can be
inserted into a slot in the front frame.
Two filter stages accept rectangular 60x75mm and 60x100mm GLASS FILTERS,
or ARRI FILTER HOLDERS with frame for 2" square gelatine or glass filters. One
of the stages can be rotated for use with GRADUATED OR POLARIZING
FILTERS. (For filter listing see separate filter price list). The rear opening of the
matte box is threaded to accept a screw-in adapter ring for Series 8 mounted
filters.
Universal Matte Box
The Universal Matte Box, especially designed for Zoom lenses also
accommodates many standard and telephoto fixed focal length lenses. Features
include adjustable front and rear standards, two filter stages, one of which may
be rotated for polarizing filters. 3"x3", 75mmx100mm graduated filters, and 4"x4"
filters can be used.
