SL-35 MARK III
INSTRUCTION MANUAL
INTRODUCTION
The SL-35 Mark III camera is built specifically as a lightweight 35mm Motion Picture
Camera. Weighing less than 2.4 kg this new camera is ideal for Steadicam, mounts, and
remote uses. Lightweight materials such as magnesium and Delrin Plastics are used to
one of lightest crystal controlled 35mm cameras made.
This advanced camera system features a specially modified Arriflex 35mm camera,
remanufactured Arriflex 2C High Speed movement, and proprietary camera electronics.
The system comes with a video door, or may be used with Arriflex or Jurgens doors.
The SL-35 Mark III can be used with a variety of magazine configurations. PL, Super
PL, Panavision, and Panavision Super 35 lens mounts are also available.
HISTORY
The SL-35 Mark III camera is actually a new concept from on an old idea. Each SL-35
Mark III is based on a special Arriflex camera similar to an Arriflex 2c that was used in
the medical industry. These cameras were used in medical angio and cath labs, where
they were used for fluorography. Now, after 8 years of research and development, and
new advances in plastics and electronics, an old camera has be re-born.
PACKING AND SHIPPING
When transporting the camera always do so without a lens, magazine or additional
accessories attached to the camera. The lens port and Magazine port covers should
always be used. Also when Shipping, use a case suitable for the camera’s size and
weight. Such cases are available from a variety of manufacturers or from SL Cine.
PARTS IDENTIFICATION
MOUNTING THE CAMERA
When mounting the use caution when using the center hole. Only a screw that protrudes
less than 4mm can be used. The film transport tray inside the camera can be permanently
damaged if the screw is longer than 4mm.
CAMERA POWER
The SL-35 Mark III is designed to work with 24 – 30V DC batteries. Check with SL
Cine to see if your batteries are compatible with the camera.
CAUTION! Make sure that the polarity of the battery is congruent with the polarity
needs of the camera body, as failure to do so can result in permanent damage to the
camera’s electronics.
ACCESORY POWER SUPPLY
12 V accessories can be attached to either of the two 11 pin accessory sockets. These
sockets each provide 4.25A of power.
24 V accessories can be attached to either of the two lemo pin accessory sockets on the
front of the camera. Each Socket provides the same voltage as battery.
MOUNTING LENSES
When mounting a lens, be sure that the lens and the mount are free from debris. Rotate
the lens mount lever counter clockwise until the mount hits the stopper. Remove the lens
port cover and insert the lens. Once the lens is properly seated, rotate the lens mount
clockwise until the lens is seated snugly. It is good practice to slowly advance the
inching knob to assure that the mirror shutter is not being hit by the back of the lens
before starting the camera.
As mentioned earlier, PL, Super PL, Panavision, and Super 35 Panavision mounts are
available for the SL-35 Mark III. Also keep in mind that the SL-35 Mark III has a full
gate and allows for full frame exposure no matter which format you are shooting.
REMOVING THE DOOR
Each SL-35 Mark III comes with a completely redesigned video door. To remove the
door, remove the video camera power cable. Then slide the door latch to the left. The
door can now be removed for film loading. To replace the door, reseat it so all edges are
snug against the camera body and move the door latch to the right. Pull lightly on the
door to assure yourself that the door is locked into position. Replace the video camera
power cable.
NOTE: It is a common practice among camera assistants to tape around the edges of the
door to add peace of mind and guard against light leaks.
ATTACHING MAGAZINES
To attach a magazine, turn the magazine release knob counter clockwise until it “pops”
away from the camera body. Remove the magazine port cover. Remove the Video Door
and open the gate. Insert a magazine into the magazine port while carefully guiding the
film through the magazine port and into the open gate (see THREADING THE FILM).
Turn the magazine release knob clockwise until the magazine is securely attached.
NOTE: Some SL-35 Mark III’s have a magazine release knob on the side of the camera.
To release the magazine port cover, pull the knob out and then turn it counter clockwise
until the cover can be removed. Follow the procedure as outlined above. Once the
magazine is seated, rotate the knob clockwise until is secures the magazine.
THREADING THE FILM
Remove the Video Door and open the gate door and attach the magazine as previously
explained. The magazine loop should have 54 perforations. Insert the loop into the gate.
You may have too use the inching knob to move the pulldown pin away from the gate to
allow the film to seat. Inch the pin to the top insertion point. Adjust the pin / perforation
relationship so the top loop is in line with the loop marking printed inside the camera.
When this is achieved, close the gate door. Inch the movement to make sure all is seated
and running properly. Test the camera by turning it on and by watching and listening for
any problems.
ELECTRONICS
One of the most exciting features of the SL-35 Mark III is the advanced electronics
designed specifically for the camera. Years of research and development have led to a
crystal controlled drive mechanism that can run the camera from .01 – 80 frames per
second. Also compatibility with external speed controllers and other accessories has
been maintained.
SPEED CONTROL
Desired camera speed can be programmed in two different ways:
1. Mode Selector. Preset camera speeds are engraved on the electronics face plate and
are adjustable by rotating the mode selector. The selected mode is displayed on the left
side of the LED screen. All speeds are crystal controlled. The mode selector was
designed to be used with SL Cine’s underwater housing. Camera speed can be adjusted
from outside of the housing easily by a knob that connects to the mode selector.
NOTE: The mode selector has priority and preempts any speed indicated by the Digi
Switch
2. Digi Switch (Push Pin Switch). Any speed from 00.01 to 80.00 Fps can be selected.
All speeds are crystal controlled. Settings on the Digi Switch are only recognized when
the mode selector is set to “A”.
The camera is started and stopped by use of the Run / Stop toggle Switch.
REVERSE OPERATION
The camera can be operated in both forward and reverse. To select reverse, use a small
flathead screwdriver and turn the selector until the reverse LED lights red. All camera
speeds are respected in both forward and reverse.
LED DISPLAY
At rest, the LED display shows the footage shot in feet and frames. At run, the frames
indicator is replaced by camera speed (i.e. 24 FPS)
FOOTAGE RESET
The footage counter can be reset at magazine changes simply by depressing the Footage
Counter Reset Button. The footage counter is also fully functional in reverse.
CAMERA ACCESSORIES
External speed controllers and remote switches can be used by connecting them through
one of the two Fischer 11 connectors on the back of the camera. Each of the connectors
can provide up to 12V and 4.25 amps of supporting power.
24 Volt accessories can be powered by one of the two power connectors on the front face
of the camera. These ports reflect the voltage of the main power battery.
CHANGING LENS MOUNTS
Lens mounts should be performed and checked by qualified individuals. Not doing so
can result in unacceptable images.
When changing from a standard mount to a Super 35 mount, a new ground glass holder,
ground glass and reducing lens must be installed. These parts and specific instructions
are available directly from SL Cine
Maintenance
Lubrication:
Approximately every 40,000 – 50,000 feet, or about once a year, the camera should be
sent in for general lubrication maintenance.
The camera has bee designed to be relatively maintenance-free. Regular maintenance is
the best protection against camera problems
