Olympus OM system
From Wikipedia, the free encyclopedia
The Olympus OM system was a line of 35mm single-lens reflex cameras and their associated lenses and accessories sold by Olympus between 1972 and 2002 (some accessories were sold through early 2003).

[edit] Camera models
Olympus produced a wide variety of OM camera models over the years. These were divided into two distinct series. Cameras with single-digit model numbers were the professional series, optimised for features and ruggedness rather than ease of use. Two-digit (or more) model numbers, or letters, meant a consumer camera designed for ease of use.
All the consumer-grade models were discontinued after 1992, since the market for manual focus cameras in this segment had dried up. Professional and advanced amateur demand for the high-end models continued, and they were produced until 2002.[1]

[edit] Professional cameras
[edit] OM-1
The Olympus OM-1 is a manually operated 35mm single-lens reflex camera forming the ground of the OM system introduced in 1972, at first called the Olympus M-1, Leica disputed this designation and it was changed to OM. It was designed by a team led by Yoshihisa Maitani with a through-the-lens exposure meter controlling a needle visible in the viewfinder. It was noted for its reduction of size, weight and noise. These features were essentially retained on later models.
[edit] OM-2
Introduced in 1975, the Olympus OM-2 was a semi automatic, aperture priority camera based on the OM-1 body, retaining compatibility with accessories and lenses. It boasts automatic through-the-lens (TTL) off-the-film (OTF) metering: exposure was considered very accurate, calculated by the measured light reflected off the surface of the shutter and/or the film surface during the actual exposure. The camera also offered a manual light-meter mode, as in the OM-1. It also introduces the integration of electronic flash into the exposure system via the same TTL exposure system.
[edit] OM-3
The OM-3 was an updated version of the OM-1, a manual camera without automatic exposure modes, and an entirely mechanical shutter. It featured a multi-spot metering in addition to the centre weighted metering on the earlier body.
[edit] OM-4
The Olympus OM-4, an improved version of the OM-2, was manufactured from 1983 to 1987 introduced at US$685 list price for the body alone. It was a battery powered electromechanically controlled manual focus SLR with manual exposure control or aperture priority autoexposure. It used a horizontal cloth focal plane shutter with a speed range of 240 to 1/2000th second plus bulb and flash X-sync of 1/60th second.
It was the first camera with a built-in spot meter[of a narrow angle, see Canon FTb](2% of view; 3.3˚ with 50 mm lens) and could measure nine individual spots and average them. The light meter used a dual concentric segmented silicon photo diode to provide spot or centerweighted readings. It used a graduated linear LCD display for the shutter speed at the bottom of the viewfinder to precisely indicate its readings versus the actual camera settings instead of a needle.
In 1986 it was improved to a tougher OM-4Ti (OM-4T in USA) version, with titanium top and bottom plates, improved weatherproofing and high-speed sync with the flash staying on during the entire shutter operation, losing the light hidden by the curtains. This last version was finally discontinued in 2002.

[edit] OM-10
The OM-10 hit the markets in June 1979 at the same time as the OM-2N. The camera is a 35mm focal-plane shutter aperture priority AE SLR camera with an electronic shutter. Only aperature priority AE was available with the camera unless the optional manual exposure adapter was installed which allowed the setting of shutters speeds between 1 second and 1/1000 of a second (bulb mode is also available on the camera). The camera is equipped with a fixed pentaprism viewfinder which contains an LED exposure indicator. The finder coverage was measured to be 93%.
Exposure control is based on aperture priority AE or center-weighted light metering. Film speeds of the camera range from ASA 25 to ASA 1600. Film winding is done by using the film wind lever located on the top right of the camera. Film rewinding is done manually using the film rewind crank located above the film canister on the top left of the camera. The camera body measures 136 × 83 × 50 mm and weights approximately 430 g.
[edit] OM-20
The OM-20 (sold in the United States as the OM-G) was essentially a bug fixed refinement of the OM-10, the mode switch was made much easier to use than the tricky switch on the OM10. It also has a built in Shutter speed dial, lights in the view finder to show the mode as well as a few more minor design improvements.
[edit] OM-30
Essentially an OM-20 with Auto-focus capability. With a normal lens there are lights in the view finder to help aid the user with focusing, a special Autofocus lens was also available at the time but is now very rare.
[edit] OM-40
A further refinement of the OM-20 with features that are more of interest to most serious photographers. It it has a lighter slightly more modern and ergonomic body design. It also had an early form of Matrix metering and full mirror lock-up when the self timer is switch on, a feature still rarely found in non high end cameras.
[edit] OM-2000
Essentially a Cosina made SLR with an Olympus badge, not considered by many to be a true OM camera.
[edit] Prototype cameras
[edit] OM-X
During the design study of the OM-1, the Olympus design team led by Yoshihisa Maitani had worked on a completely modular camera, like a 35 mm Hasselblad. This camera was built as a prototype, and was called the OM-X.[3]
[edit] Lenses
The OM Series lenses have the aperture control located on the lens barrel on the opposite side of the focusing ring from the mount. This was done to move it away from the shutter speed control, which is a ring on the camera body immediately behind the lens mount.
The OM lens is designed to sit 46 mm from the film onto which it projects, further away than many other lens systems. The combination of on-lens aperture control and this extra distance make OM lenses adaptable with full (manual) functionality to a variety of other camera systems, including the ubiquitous Canon EOS line with a specialized adapter.
