6.2 CAMERA CONVERSION
The 35-III camera can easily be converted from Standard35 to Super35
and back. A quick lateral sliding of the viewfinder and lens mount,
that’s all there is to it.
6.2.1 Lens-Mount Repositionning
The lens-mount is on a titanium seat which rests on the camera
main chassis ; this seat can laterally move by 1.27mm between two
stop pins. To have access to the seat, remove the two front rods and
the lens locking ring, unscrew the four retaining screws of the front
cap and remove the cap. The titanium lens mount seat is now
accessible. Loosen (3 or 4 turns) the three screws which appear in
elongated cut-outs ; push the titanium seat against the pin on the
VIDEO-ASSIST SIDE to set the camera in SUPER35 (or push the
titanium seat against the pin on the DISPLAY SIDE to set the
camera in STANDARD35). Retighten the three screws, reinstall the
front cap, the lens locking ring and the front rods.
Please note: if you are frequently swaping formats, it is advisable to
install a Super35 engraved (or Standard35 engraved) front cap ins-
tead of the universal front cap delivered with the 35III camera.
These format specific caps can’t be fixed on the central chassis if the
titanium seat is not in the position engraved on the cap itself ; this
external engraving brings peace of mind to the camera-assistant and
to the prep. people.
6.2.2 Shifting the Viewfinder
The optical axis of the viewfinder need to be set to the optical cen-
ter of the main taking lens. The viewfinder and the carrying handle
form a block, which can easily be shifted laterally. This block is
attached to the camera central chassis by 4 screws located at the base
of the carrying handle. To set the viewfinder to SUPER35, loosen
the 4 screws, shift the handle toward the VIDEO-ASSIST side
