Mamiya feels confident that the extensive versatility and capabilities of the Pro-S will meet and satisfy the requirements of all photographers. 1. Rational 6 x 7cm format Since the 6 x 7cm format covers an area 4.5 times the 3 5 m m format, excellent picture quality is obtainable. Especially, it demonstrates superb results in color photography. The ratio between the length and width of 6 x 7cm formats is almost the same as that of large photographic paper, permitting economical enlargements without cropping. When designing a magazine layout, a sufficient blank space is reserved for headlines and explanatory notes, s o that the entire picture format can be fully utilized. 2. Single-lens reflex camera offering a bright, large finder image Since parallax-free focusing in the outstanding feature of the single-lens reflex camera, speedy camera operation is possible through brilliant, precise 6 x 7cm picture composition. 3. Excellent Mamiya Sekor lenses Mamiya Sekor lenses boast excellent image rendition and color balance. Various types ranging from wide-angle lenses to telephoto lenses are available. 2 These lenses are rationally grouped in series, whereby those exactly adaptable to one's particular photographing objectives are optionally selectable with ease. 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. 4. Lens-shutter system suitable for electronic flash photography By adopting the lens-shutter system, electronic flash is synchronized with all shutter speeds, making it possible to produce highly impressive photographs. 7. Finder format index interlocked with revolving adapter When the revolving adapter is turned up to 90", horizontal format picture index red lines appear (or disappear), presenting proper picture composition. 5. Double-exposure prevention and multiexposure devices An interlocking device for double-exposure prevention is incorporated 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 exposure 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. 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 photographing 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, 3 and 70mm film. The film holders and back adapters are very easily exchanged. on the photographing objectives, a checker, a rangefinder spot, a microprism, and a cross-hair can be selected at your option. 10. Unique mirror shockless mechanism By adopting a unique centrifuged friction governor system, the mirror functions smoothly without sensing shocks. Mirror shock, constituting the most important problem involved in large, singlelens reflex cameras, has been solved. 12. Excellent heat- and cold-resistant capacity Camera component parts are capable of demonstrating their functions within a wide temperature range from approximately 120°F to - 5OF (5OOC to - 2OOC). The lens-shutter maintains accurate function, even in severe cold, and shutter speed deviation is negligible. Its resistivity to coldness is superb. Although the camera operating unit grows sluggish at or below 15OF (-loo C), it is sufficiently capable of operating the camera until the temperature drops to approximately - 50° F (-ZOO C). 11. Large variety of finders A big selection of finders conforming to your photographic objective are available. They include a CdS finder (appropriate exposure obtainable with Through-the-lens measuring system), a Prism finder (subjects can be seen as an erect image), a CdS prism finder (former two types of finders are combined). a Magnifying hood (easily visible and bright), a Dual magnifying hood (performs precision focusing by speedily changing the magnifier of high magnification), and a Universal sportsfinder (permits focusing on the focusing screen after it has been installed). The focusing screens are also easily exchangeable. Depending 13. Mirror-up photography (independent mirror release) possible When sharp pictures are demanded, the mirror-up mechanism plays a big role. When taking a picture unhurriedly with the camera mounted on a tripod. or when photographing at slow shutter speeds or using a telephoto lens, the mirror-up operation merit is highly effective. 4 14. Close-up photography through full use of bellows characteristic features Since the bellows can be extended up to 46mm, photographing small subjects in the frame full size is possible. When auto extension tubes are used, the subject can be further enlarged. When a standard lens is employed, life-size (1 : 1) or larger pictures can be photographed. 17. Dark slide lock for safety while carrying A dark slide lock is provided for the Pro-S roll film holder so that the dark slide will not slip off while carrying the holder detached from the camera body. 16.
