SECTION Ill
General
The
Eclair 16
is provided with a turret with 2 lens mounts: one for "CA"
(Cameflex) mount (E 51), the second for universal "C" mount (E 49).
The dimensions for the focal length from the film plane to the bearing
face of the lens are respectively:
48 mm. -0
and 17.52 mm. -0
+0.01
+0.01
On request, the
Eclair 16
can be supplied with 2 "C" mounts, however,
the use of "CA" mount lenses is strongly recommended, as this mount
provides a superior seating, especially for zoom or long focal length
lenses.
Positioning the turret (E 50)
1. Turn central knurled button (F 54) in the direction of the arrow "D".
2. Pull out the button (F 54) to remove the turret from its housing.
3. Turn the turret through 180
°
.
4. Push the turret back to its new position, without forcing.
5. Lock button (F 54) by turning in the direction of the arrow "S".
Fitting the lenses
The distance between the axes ofthe 2 lenses allows the simultaneous
mounting of a short focus lens, KinoptikTegea F-5.7 mm. (or Angenieux
F- 10 mm.) and an 12 x 120 mm. zoom without the latter entering the
field of the short focus lens. Reflex viewing allows full advantage to be
taken of this feature in all situations.
"C" Mount:
Remove protective cover (F 49), screw the lens firmly into place without
using unnecessary force.
"CA" Mount:
Remove protective cap (E 51) by turning it counter-clockwise and then

Lens turret
pulling it out. Push the lens mount into the cup taking care that the slot
in one of the flanges locates on the stud which is at the top of the cup;
turn the lens clockwise to lock it. Do not force.
Always replace the protective cap into the mounts when no lens is
mounted to prevent dust entering the camera.
Intermediate mounts:
The following can be supplied:
- CINTA for converting lens cup "C" (F 49) to "CA" mount (Cameflex)
- CARRI for converting lens cup "CA" (E 51) to "Arriflex" mounts
- CIRAD for converting lens cup "C" (F 49) to "Arriflex" mounts.
The above intermediates should only be considered for emergency use,
as the "Intermediate/Lens" unit will not assure precision especially
with zoom or long focus lenses.
Lens holder
For zoom or long focus lenses, the use is recommended of an (E 33)
support with (E 34) rod, which fits in socket (E 32). To place this rod in
position, remove the knurled button
.
(E 35), push the rod in the socket,
groove downwards. Tighten button (E 35). Place the lens in position
and raise the support (E 33) until it is in contact with the lens. Tighten
the knurled buUon of the support.
Matt box:
Bellows type matt boxes can be supplied.
CIPAR (F 57), with two mounts for 60 x 85 mm. filters, one of which
is free to swivel.
RO PAR, with two mounts for square 76 x 76 mm. filters, one of which
is free to swivel.
The swivelling filter-holder may be used for polarising filters or for a
graduated sky light-filter.
