The automatic exposure control of this model is based
on the proven PENTACON internal light metering system through the
lens (TTL) with beam splitter, condeser and photo resistant cell.
With it the correct exposure is regularly obtained, as only the light
which is used to produce the picture takes part in measuring.The measuring
angle and the picture angle of the lens areidentical and theexposure
factors for filters and extension accessories are covered when measuring.
A genuine exposure auotmation is obtained: either the aperture or
the shutter speed are pre-selected and the appropriate second factor
for the exposure is obtaiined by lining up the pointer with the indicator
in the viewfinder. Metering is done stopped down by depressing the
conveniently designed measuring key which is arranged close to the
Plus and minus symbols above and below the mark in
the viewfinder warn against over- and under-exposure.
Other technical features of this model: steel blade
focal plane shutter (shutter speeds 1/500 to 1 sec. and B). Flash
synchronisation for electroniic flash units and flash lamps: flash
connection through centre contact of the integral accessory shoe,
and flash socket for cable connection at camera front (two flash units
can so be simultaneously used even if they are of different electrical
connection - convenient utilisation of the dual flash technique).
Shortest synchro speed for electronic flash units about 1/125 sec.
Prism finder with large brightest finder image being always true to
side and upright. Readiness indicator in the viewfinder. Brightness
increasing Fresnel lens with metering wedges, micro-prism centre,
and matt glass ring for fine focussing. Automatic PL-Filmloading for
the simplest loading imaginable. Conveniently placed angled shutter
release. Return mirror (the finder image is practically always visible
and disappears only for the duration of the actual exposure which
is generally only a fraction of a second). Quick cocking lever with
short winding angle. Hinged-on back. Automatic frame counter (self-resetting
on opening the back of the camera). Pleasant elastic camera cover.
