Mechanical
system
Electric motor,
electronically regulated by impulses, for optimum use of the power
of the battery and perfectly constant filming speeds
Filming speeds of 10, 12, 18, 20, 24, 25, 32, 40 and 50 f.p.s +
single-frame. • 24 and 25 f.p.s. filming speed accuracy in accordance
with sync pulse standards
Possibility of sound synchronization with crystal control accessory
at 24 and 25 f.p.s. (Maximun deviation for 400 ft of film: less
than one frame) Camera stops with shutter closed for all functions.
Practically instant start and stop, with no noticeable overexposure
of the first or last frame of a take
Unlimited reverse running.
Built-in device for testing the power pack charge. The electric
current is automatically switched off as soon as the power pack
voltage drops below the critical level.
170° rotary shutter opening. Automatic film threading. Spool ejector.
Loop former. Powered by SAFT NiCd battery with low internal resistance,
nominal voltage 12V - DC. |
Light
meter
High performance, built-in light meter. Through-the-lens measurement
of the light by a cell which fits in front of the filming aperture
while de diaphragm is being set. Instant reaction, linear characteristic
silicon cell, for electronic processing of the data: film sensitivity,
filming speed, exposure of the cell. It has no memory and is practically
insensitive to blinding, ageing and variations in temperature. Sensitivity
range: 25 to 1600 ASA (15 to 33 DIN) with automatic coupling at all
filming speeds. The silicon cell is "adapted" to the spectral sensitivity
of the film by an optical filter. Measurement of the light in the
centre of the field of view over about 35% of the picture area. Manual
operation of the diaphragm setting ring, the correct opening being
set by balancing the brilliance of the two light-emitting diodes located
in the viewfinder. Possibility of detecting an over - or under - exposure
of 1 stop. |
