These lenses are rationally grouped in series, whereby those
exactly adaptable to one’s particular photographing objectives are
optionally selectable with ease.
4. Lens-shutter system suitable for electronic flash
photography
By adopting the lens-shutter system, electronic flash is synchro-
nized with all shutter speeds, making it possible to produce highly
impressive photographs.
5. Double-exposure prevention and multiexposure
devices
An interlocking device for double-exposure prevention is incor-
porated in the Pro-S roll film holder. Since this device is interlocked
with the Pro-S body mechanism, the shutter cannot be released
unless the film is advanced. Also, film advance for the next expo-
sure is impossible unless the shutter is released.
When the shutter is released, the film wind-stop is automatically
released.
Multiple exposure photography is available simply by switching a
lever.
6. Vertical or horizontal picture format quickly changed
over with the revolving adapter
A revolving adapter is provided as a standard outfit, whereby the
vertical or horizontal picture format is promptly selected by turning
the camera body back by 90°. without changing the camera position.
This is especially convenient when the camera is mounted on a
tripod.
7. Finder format index interlocked with revolving adapter
When the revolving adapter is turned up to
horizontal format
picture index red lines appear (or disappear), presenting proper
picture composition.
8. Excellent film flatness ensured by Pro-S roll film holder
Various tests have been applied to the Pro-S roll film holder to
stabilize film flatness. As a result, film flatness has been further
improved.
9. Camera back adapter changeable according to photo-
graphing objectives
By changing the back adapter, depending on your photographic
objective, the range of film applications can be widened to include
120 and 220 roll films, dry plates, cut films,
