ANGENIEUX ZOOM LENS

INSTALLATION
Panhandle
1. Loosen the three thumbscrews so that
they do not protrude into the interior of
the panhandle.
2. With the focus drag control in the up
position, gently slide the panhandle onto the
panhandle shaft. A male and female hexagon
focus shaft assembly must mate with each
other; therefore, DO NOT force the pan-
handle on to the associated shaft.
3. Tighten the three thumbscrews until the
panhandle is firmly secured to the associ-
ated shaft.
4. Loosen the handle bolt and position the
panhandle to
suit the Color Camera oper-
ator, then retighten the bolt securely.
CAUTION
IF THE PANHANDLE IS RE-
MOVED FROM THE CAMERA,
COVER THE SHAFT WITH A PRO-
TECTIVE MATERIAL TO AVOID
DAMAGE.
Extenders
The extenders are shipped from the fac-
tory with their focus ring correctly set
allowing for installation without having to
make focus adjustments. If, however, focus
tracking cannot be attained, the procedures
under Focus Tracking, below, must be per-
formed.
Although the extender increases
the focal length of the Zoom Lens, the focal
length meter on the Camera viewfinder
indicates only the focal length from 18mm
to 180mm. To obtain the focal length with
an extender in use, the meter reading must
be multiplied by the extender focal power,
either 2X or 3X.
1. Release the two cam locks securing
the removeable panel from the overall Zoom
Lens drive assembly shroud.
2. Remove the panel.
3. Using the thumb and forefinger, reach
underneath the shroud and loosen the two
thumbscrew lens locks.
4. Slide the Zoom Lens drive assembly
forward so that the extender can be instal-
led behind the Zoom Lens.
5. Screw the extender onto the end of the
Zoom Lens.
6. Return the Zoom Lens drive assembly
towards the Camera until the extender focus
ring fits
snugly against the front of the
Camera.
7. Tighten the two Zoom Lens bed thumb-
screws.
8. Run the Zoom Lens to
its narrow -
angle
position and focus the Lens using
the
panhandle grip focus control. Check
focus
tracking through the
entire
range
of
the Zoom lens.
If
it
is not attained,
perform the steps under Focus Tracking,
below.
Focus Tracking
1. Loosen the three Allen screws that
secure the extender focus ring to the exten-
der.
2. Rotate the zoom control until the Zoom
Lens is in its wide-angle position.
3. Make certain that the extender is seated
against the front of the Camera, then ro-
tate the extender focus ring until the pic-
ture on the Camera viewfinder is in focus.
4. Rotate the zoom control until the Zoom
Lens is in the narrow -angle position.
5. Rotate the panhandle grip focus con-
trol until the picture on the Camera view-
finder is in focus.
6. Return the Zoom Lens to the wide-
angle position and recheck to insure that
focus tracking has been maintained.
7. Return the Zoom Lens to the narrow -
angle position and recheck to insure that
focus tracking has been maintained.
8. If, after initially setting
the focus
ring, focus
tracking cannot be achieved,
steps 2 through 7 must be repeated until
it is.
