Characteristics
• Type of photometer: to adjust by comparison
manual setting of aperture ring.
• Type of measurement: behind the lens (T.T.L.)
semi-spot 4 mm dia, angle 100 with F. 25 mm
semi- spot 7 mm dia, balanced at 50%.
• Sensitivity range: 25 to 400 ASA.
• Sensing element : rapid response C D S cell.
compensated sensitivity range.
• Display: 7 Light emissive diodes (LED) resolu-
tion interval, 0,5 dia/1 dia/1.5 diaphragm.
• Light computation : resolving prism (= 25 % on
the CIDS cell) neutrallsing the semi-reflective
deposits.
• Compensation Stop-go: electronic compensa-
tion; automatic compensation.

Audible warning device in magazine:
This system S (fig. YZ) also called
« ghost indicator » functions if the film loop is
resorbed; it produces a clicking sound which
warns the cameraman.
resorbed; it produces a clicking sound which
warns the cameraman.
In that case :
• Stop the camera and remove the magazine.
• Check the loop and divide it normally.
• Re-mount the magazine on to the camera.
• Restart the camera.
• Check the loop and divide it normally.
• Re-mount the magazine on to the camera.
• Restart the camera.
Should this occur again, check in a
changing bag the threading of the magazine;
you will probably find a film jamming due to
some damaged perforations.

The light intensity received by the
photo resistive element is compared with the
reference determined by the gauge, and
intensity already memorised by the computer
(fig. U).
The seven diodes are mounted on a ceramic
base situated next to the ground glass,
outside the field of view (fig. T); they indicate
the zero or the difference in aperture (either +

1.5 stops, each diode representing about one
half stop (fig. U).
