If the Exposure Needle Does Not Center on the Index
If an exposure or a shutter speed is improperly selected, the exposure needle will not center on the index. Reset the shutter speed or F stop until the needle is centered. You may use an ND (neutral density) filter if the subject is too bright, or an electronic flash or flash bulb if the subject is too dark.
Light Measuring Range of the Exposure Meter
The measuring range is EV 1.5-EV17 (ASA 100, with F1.2 55mm lens). The list above summarizes the lowest measurable limits in dealing with extreme low light conditions.
CAUTION: If the aperture ring or shutter speed ring is turned below the limits in the list, with ex-
tremely low lighting or the selector lever OFF,
the needle sometimes moves, but the meter is not functioning.

Transport the film advance lever with your right thumb and squeeze the release button smoothly using the cushion, not the tip, of your index finger.
NOTE: For telephotography, or slow shutter speed photography, it is recommended that you use a tripod and hold the camera steady with

your hands.

UNLOADING THE CAMERA
MAKING MULTIPLE EXPOSURES
Should you wish to make more than one exposure on the same frame:

Can I operate the camera without the motor drive socket cap in place? No. Light will enter the camera body through this hole, fogging the film. Also, dust and dirt may enter, causing a camera malfunction. Why doesn't my electronic flash unit fire when I release the shutter? If the shutter speed is 1 /125 second or faster in conjunction with the electronic flash T32 or T20, the built-in incorrect flash prevention system does not permit flashing. Confirm the shutter speed. (See page 31.) Why do I feel a small electrical shock when I touch the terminal contact of the accessory shoe? This is normal when using a side-mounting type flash. When using flash that is not connected to the accessory shoe, remove or cover the shoe.

OM SYSTEM

The OM System is comprehensively arrayed to meet an ever-expanding universe of photographic conditions for any subjects from the stars to microorganisms. 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.

INTERCHANGEABLE LENS GROUP UNITS

Lens Hoods

Lens hoods protect against extraneous light striking the lens and causing unwanted glare. Hoods for standard lenses are cover types and can be reversed to provide easy storage even when the camera is in the case. Five lens hoods are optionally available (see TABLE OF INTERCHANGEABLE LENSES on pp. 53-54).

FINDER GROUP

The viewfinder is one of the most important features of a single lens reflex camera. Since every photographic subject is turned into a visual image by means of the finder, a finder that is dark or difficult to look through is an obstacle to good photography. However enriched an SLR camera is with a wide range of interchangeable lenses, the SLR cannot be expected to fulfill its essential function without the provision for changing of focusing screens. The OM-2 is provided with a viewfinder that offers a far brighter, large image than previous 35mm SLR cameras. The Finder Group supplements this basic advantage with a comprehensive set of 14 focusing screens for a wide variety of applications from photomicrography to astrophotography. Unless the most suitable focusing screen for a given photographic purpose is available, the potentialities of a system camera cannot be utilized. For fast, accurate focusing, the OM System Finder Group offers the unique Varimagni Finder with a magnification selector, the Eyecup 1 that accepts a variety of Dioptric Correction Lenses, Eyecoupler, etc.

Since the outer area has a matte surface, the screen can be used in the same way as the standard 1-1 and 1-3 Screens. When a lens with a maximum speed of F5.6 or slower is used, the prisms darken and the focusing must be made on the matte area. Most suitable for normal photography. The central split-image range finder, encircled by a microprism collar, is inclined 45 degrees to allow easy focusing on subjects with vertical or horizontal lines.

MOTOR DRIVE GROUP

The attraction of the motor drive is its ability to capture fleeting phenomena which exceed the capabilities of human response. Tailored perfectly to match the OM camera body, each unit of the Motor Drive Group has been reduced in size to enhance its maneuverability and ease of operation. The basic motor drive package (Motor Drive 1 + M. 18V Control Grip 1,or Motor Drive 1 + M. 15V Ni-Cd Control Pack 1) features an amazingly compact and lightweight design, permitting handheld photography even with a 300mm telephoto lens, for shooting sports and news events or other action subjects. The Winder 2 is designed for the ultimate compactness operating on self-contained batteries to perform single or sequential shooting. The 250 Film Back 1, which holds enough bulk film to give 250 exposures, attaches to the OM camera body without cords. The M. AC Control Box is useful for copy work, time-lapse and other photography by transforming household current to DC for motor drive use via a relay cord. The many uses of the units of the Motor Drive Group in conjunction with other units of the Macrophoto, Photomicro and Flash Photo Groups permit even a greater range of photographic possibilities with the motor drive than originally imagined.

MACROPHOTOGRAPHY GROUP
Due to recent advances in macrophotography, it has become possible to discover patterns and colors of unsuspected beauty in the minutiae of nature. A fast growing number of scientists and amateurs are taking the opportunity to explore the living world around them to new depths. The Macrophotography Group of the OM System provides all the tools necessary to capture this world of perfection on film, offering a complete
range of convenient high performance accessories
designed for specialists in the various fields of macrophotography. Starting from close-up photography with simple accessories such as Close-up Lenses, and Extension Tubes, you can extend your photographic excursions into the macrophoto world with the five Macro Lenses, Auto Bellows, Stands, Adapters, and a large variety of lighting equipment. This Group has no equal in its wide variety of accessories for macrophotography with a magnification range from 1/1 Ox to
about 10x, and heightens the value of the OM
