User manual OLYMPUS OM-2

[. . . ] To an OM-2 Owner The OM-2 is a unique 35mm single lens reflex, utilizing the Olympus TTL Direct (Off-the-Film) Light Measuring System for unprecedented accuracy of automatic exposure. In addition, it offers full manual exposure control at the flip of a lever switch. OM-2 has set a new standard for reliability and versatility in a compact SLR, to meet the demands of the professional and amateur alike, for standard as well as scientific and technical photography pursuits. OM-2 is part of the total Olympus OM System, enabling you to capture life as it happens, from photomicrography to astrophotography, from photojournalism to portraiture. [. . . ] The sensors measure flash intensity as it builds up and cut off its light at the source when the correct exposure level is reached. Even during 5-frame-per-second motor drive operation, this Method insures correct ex- posure for each frame individually. The Method operates accurately in far dimmer light than other systems.

A full-scale system camera is distinguishable by some of the prerequisite characteristics as broadly mentioned below: · Interchangeability of focusing screens. · Adaptability to high speed motor drive photography. · A wide range of high quality system components, including interchangeable lenses. · Compatibility of the camera body with an electronic flash unit allowing high technic flash photography with extreme ease and accuracy. · Tough and reliable shutter, viewfinder, etc. that withstand harsh handling without failing. When these exacting conditions have been satis- fied, an OM-2 is born as a true system camera that controls an entire SLR comprehensive system. The OM-2 is backed up with over 300 components systematically organized under eight groups -- Interchangeable Lens, Finder, Flash, Motor Drive, Phototechnical, Macrophoto, Photomicro and Case. 50 ZUIKO INTERCHANGEABLE LENS GROUP One of many advantages of the single lens reflex camera is the large variety of interchangeable lens- es available. The Zuiko Interchangeable Lens Group (designed and manufactured by Olympus) comprises 33 lenses. Zuiko lenses have always enjoyed a high reputation in photographic circles -- the most modern design technology and employment of newly developed optical glass have made possible a new series of innovative, high performance lenses. These lenses have a host of special features including new construction that compensates for close focus aberrations, increased aperture ratio in the wide angle lenses, and reduction in telephoto lens size and weight. The OM System adopts 49mm filters for most lenses from 21mm to 200mm. As part of the OM System design all the lenses now offer higher performance in small configurations. Olympus has produced lenses for microscopes for decades and the new Zuiko lenses benefit from this scientific experience. See the "OM System Zuiko Interchangeable Lenses" manual for further information. 51 TABLE OF INTERCHANGEABLE LENSES OPTICAL TYPE INTERCHANGEABLE LENSES ANGLE OF VIEW CONSTRUCTION DIAPHRAGM AUTO. ) ELEMENT-GROUP FISHEYE ZUIKO FISHEYE ZUIKO FISHEYE ZUIKO MC ZUIKO MC ZUIKO ZUIKO MC ZUIKO (meters) 8mm F2. 8 16mm F3. 5 18mm F3. 5 180°(circle) 180° 100° 92° 92° 84° 84° 75° 75° 63° 63° 43° 47° 47° 47° 64° ~ 34° 32° ~ 16° 29° ~ 10° 29° 24° 18° 18° 14° 12° 12° 11­7 11­8 11­9 SUPER WIDE ZUIKO MC ZUIKO WIDE ZUIKO MC ZUIKO ZUIKO SHIFT ZUIKO ZUIKO MC ZUIKO ZUIKO MC MACRO ZUIKO MC ZOOM ZOOM 21mm 21mm 24mm 24mm 28mm 28mm 35mm 35mm F2 F3. 5 F2 F2. 8 F2 F3. 5 F2 F2. 8 11­9 7­7 10­8 8­7 9­8 7­7 8­7 7­7 8­6 7­7 7­6 6­5 5­4 10­8 15­11 15­11 5­4 5­5 5­5 5­4 5­5 AUTO, AUTO.
