5.1 LENS
5.1.1 Lens Elements
The front and rear surface of your lenses should be inspected regu-
larly and always kept clean of dust particles, smudges, fingerprints,
etc. First, blow off any large particles of debris using an air syringe.
Lens elements should then be cleaned using lens cleaning fluid with
lens tissue. Apply a few drops of cleaning fluid to a fresh lens tissue
or directly to the lens. Wipe the lens in a circular fashion, starting
from the center and working towards the outter edge....

port ring completely free of dirt and debris. Clean this surface, as
well as the threads of the lens lock ring using alcohol or a multi-pur-
pose cleaner applied to a Q-tip.
5.2.3 Camera Gate
The gate should be cleaned of film particles by means of a pointed
wooden or plastic orange stick. The tool used should be of a soft
and pliable enough material (like wood) to conform to the grooved
side channels of the gate without breaking. Make sure to inspect and
clean the right and left channels, the frame of...

the body. Remove the viewing screen. Clean both upper and lower
surfaces of the screen and reinstall.
5.3.2 Eyepiece
Clean the eyepiece lens, which is the outermost element closest to
your eye, by first blowing the surface with canned air, then cleaning
with lens fluid and a Q-tip. Remove the eyepiece and clean the field
lens, which is located on the inside of the eyepiece, in the same
fashion.
5.3.3 Viewfinder
Do not install the eyepiece back right now. First, look inside the
cameraÕs eyepiece seat, and...

with soft bristles to clean particles from tight crevices. Afterwards,
use canned air and thoroughly blow out any remaining dust in the
throat and chamber.

6.1 SUPER VS STANDARD 35MM
6.1.1 The Super35 Format
Super35 is a comeback to the cinema origins: silent cameras were
exposing all the available area between perforations of the 35mm
film.  When came the ÒtalkiesÓ the picture had to be reduced to give
room to the 2.54mm-wide optical sound track.  Equipment manu-
facturers had to shift the optical axis of all their cameras and projec-
tors by 2.54/2 = 1.27mm.   Sixty years later Super35 is coming back
because it records 16/9 pictures with much less of a...

cal Òreduction and axis shiftÓ at the interpositve stage. 
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,
thatÕs 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...

(until it reaches its stop), and then tighten back the screws.  To set
the viewfinder to STANDARD35, shift the handle toward the DIS-
PLAY side.
6.2.3 Selecting a Viewing Screen
There is a wide choice of Standard35 viewing screens and four
Super35 ones to the 1.78, 1.85, 2.35 and Scope aspect ratios.  To
install a new one, please read chapter II, viewing screen section.
WARNING: when shooting Standard35 DO NOT leave the camera
in the Super35 alignment, thinking that framing with a Standard35
screen will...
