44-585: The OM-4 was the successor to the OM-2N and represented the highest evolution of the Olympus OM-series SLRs (introduced in 1972). Other Olympus OM top models were the OM-1 , OM-2 , OM-1N, OM-2N , OM-2 Spot Program, OM-3 and OM-3Ti. They all used the same body configuration, but with developing aluminum alloy chassis, electronics, feature levels, and external controls and cosmetics. The OM-4 used

88-442: A built-in spot meter [of a narrow acceptance angle, see Canon FTb] (2% of view; 3.3˚ with 50 mm lens) and was the first camera capable of measuring eight individual areas and averaging them. The light meter used a dual-concentric segmented silicon photo-diode to provide spot or centerweighted readings. It used a graduated linear LCD for the shutter speed at the bottom of the viewfinder to precisely indicate its readings versus

132-500: A concomitant loss of flash range. A black-finished version of the OM-4T came out in 1990, listing for $ 1250 (the champagne-finished body remained available for $ 1200). In the US market the OM-4T was renamed OM-4Ti in 1997 ($ 1819 list) when the replacement 4T top cover supply became exhausted and it was deemed too expensive for Olympus Japan to create more. The 4Ti had no feature changes over

176-495: A horizontal cloth focal plane shutter with a manual speed range of one second - 1/2000 second (up to 240 seconds was possible in automatic mode), plus bulb and flash X-sync of 1/60 second. Unlike most SLRs of the era, the OM-4 used a familiar OM-series shutter-speed ring, concentric with the lens mount, instead of a top-mounted shutter speed dial. The OM-4 accepted all Olympus-made OM bayonet-mount lenses, which were marketed under

220-569: A needle visible in the viewfinder. It was noted for its reduction of size, weight and noise. One feature unique to the OM-1, compared to the rest of the OM system, was its mirror lock-up facility which made it ideal for astrophotography and macrophotography. Introduced in 1975, the Olympus OM-2 was a semi-automatic, aperture-priority camera featuring an electronically controlled shutter. It was based on

264-407: A new electronic flash-control system. Normally focal-plane shutters are limited in their maximum flash synchronization speed, because of the way they provide fast shutter speeds – timing the second shutter curtain to close more quickly after the first shutter curtain opens. This causes a narrowing of the slit "wiping" the exposure on the film. In effect, a horizontal focal-plane shutter made of cloth

308-613: A new lens mount, the A system , breaking compatibility with its earlier manual-focus lenses in the MC and MD system. The A lens mount is still the same today , but some modifications have been made to the electronic contacts to facilitate new functions such as motor zoom (xi lenses, now discontinued) and a more sophisticated flash metering system (ADI). Konica and Minolta merged their photo and camera businesses in October 2003. In January 2006 Konica Minolta announced that they were withdrawing from

352-494: A normal lens there were lights in the view finder to help the user with manual focusing. When used with a motor drive or winder unit and the M-In Focus Trigger cord, the lens could be pre-focused on a specific point. As soon as an object moved into that focus zone the camera would trigger a shot. A special motorised 35-70mm autofocus lens was also available at the time, but is now very rare. A further refinement of

396-655: A system, Olympus made numerous accessories for professional portrait , photo journalism , sport photography and scientific photography. Minolta Maxxum 7000 The Minolta MAXXUM 7000 (7000 AF in Europe and α-7000 in Japan) 35 mm SLR camera was introduced in February 1985. It was the first camera to feature both integrated autofocus (AF) and motorised film advance, the standard configuration for later amateur and professional single lens reflex cameras. Although

440-525: A violation of its trademark, because the XX in its logo was linked in a similar fashion. As a result, Minolta was allowed to distribute cameras that were already produced, but was forced to change the stylistic XX in Maxxum and implement this change in new production. All Maxxum cameras produced thereafter had a regularly scripted double 'X'. Minolta's autofocus design was found to infringe the patents of Honeywell,

484-450: Is only fully open and usable for flash exposure up to 1/60s. Any faster and a typical one-millisecond flash burst would only partially expose the film - the part open to the slit. The OM-4Ti overcame this problem by having the new Olympus F280 Full Synchro flash pulse its light continuously over 40 milliseconds, long enough to illuminate the slit as it crossed the entire focal plane, even at shutter speeds as fast as 1/2000s. There is, however,

528-485: The EOS 600-series a few years later, breaking compatibility with the former FL and FD lens mounts. Canon's EOS system was the only fully electronic lens mount system, with no mechanical connections between camera body and lens: the autofocus motors were housed in the lens itself, rather than the camera body. Early Maxxum 7000 cameras were inscribed "MAXXUM 7000" with a crossed 'XX'. The oil giant Exxon considered this to be

572-674: The Nikon F3AF (1983), Pentax ME F and Chinon CE-5 already had presented autofocus single lens reflex cameras, autofocusing could not be achieved without the use of special motorised AF lenses. The Pentax ME F had focus sensors in the camera body, while the Chinon CE-5 used a lens with built-in active infrared sensors. Nikon already had a camera with integrated motor drive on the market, the N2000 ( F-301 in UK), but its autofocus counterpart,

616-531: The 'professional' series, optimized for more advanced features and durability. 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 SLR cameras had declined greatly in favour of autofocus SLRs. The consumer line returned in 1997 with the Cosina-sourced OM-2000 model. Professional and advanced-amateur demand for

660-657: The 4T. The 4Ti was discontinued in 2002. Olympus failed to make the transition to autofocus (AF) 35 mm SLRs in the wake of the introduction of the landmark Minolta Maxxum 7000 in 1985. Most manual-focus SLRs disappeared by 1989. The OM-4 and OM-3 models were retained because Olympus had no appropriate successors. Their rugged construction also appealed to professional photographers, and some traditionalist amateurs who preferred manual-focus cameras. The Olympus OM-4 sold steadily to Olympus enthusiasts, but more and more slowly over its lifetime, as it became increasingly outdated. It remained in limited production until 2002, when

704-521: The N2020 ( F-501 in UK), appeared after the Maxxum/Dynax. The Minolta 7000 had its AF sensors and the focusing drive inside the camera body, and as a result the lenses could be much smaller and cheaper. The aperture and focus were mechanically driven through the lens mount from the camera body. However, electronically controlled buttons on the camera body now replaced the mechanical aperture ring on

748-410: The OM-1 body, and retained compatibility with OM-1 accessories and lenses. It boasted automatic through-the-lens (TTL) off-the-film (OTF) metering, and exposure was considered very accurate. This was 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-exposure mode, as in the OM-1. It also introduced

792-539: The OM-10, replacing that model's rather tricky mode switch with one that was easier to use. The OM-20 also had a built-in shutter-speed dial, a mode display in the view finder and a much stronger winding mechanism which permitted it to be used at 5 frames per second on the OM Motor Drive 2. The shutter magnet and release system had other minor design improvements. Essentially an OM-20 with auto-focus capability. With

836-462: The OM-2, was manufactured from 1983 to 1987. It was introduced at a 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 240s (in auto mode) to 1/2000s plus bulb , and flash X-sync of 1/60s. The OM-4 featured

880-574: The OM-20 with features that were more of interest to serious photographers. It had a lighter, slightly more modern and ergonomic body design. It also had an early form of matrix metering, and a mirror lock-up facility. This was activated when the self-timer was switched on, a feature still rarely found in non-high-end cameras. Also known in some markets as the OM-PC, the OM-40 had a program mode that automated

924-512: The OM-4 compared to the OM-2N were the stronger chassis, gasket weatherproofing, permanently affixed, dedicated hot shoe and TTL flash cable connector, linear liquid crystal display (LCD) shutter speed display, provision for spot-metering, and flexible integrated-circuit electronics. Accessories for the OM-4 included all the Olympus motor drives made for the OM-System cameras. Motor Drive 2

968-561: The OM-4 was its ability to operate without batteries due to its mechanical design. Batteries were only needed for the exposure meter and LCD. It lacked a self-timer and mirror lock-up functions, however. In 1995, nine years after the OM-3 was discontinued, the OM-3Ti was released. It shared the improvements over the OM-3 that the OM-4Ti held over the OM-4. The Olympus OM-4, an improved version of

1012-472: The OM-4's manual spot-metering represented Olympus's intention to provide precision for the professional and advanced amateur photographer. In 1986, a special ultra-durable version of the OM-4 with champagne-colored titanium top and bottom plates, upgraded electronic circuitry and improved weatherproofing, called the OM-4Ti (OM-4T in the USA), was released, with a US list price of $ 770. The OM-4Ti also introduced

1056-545: The Zuiko brand name. The OM-4 was a battery-dependent (requiring two 1.5-volt silver oxide SR44, V76, 357 cells - use of a 3-volt 1/3N lithium cell is not recommended) electro-mechanically controlled manual-focus SLR with manual exposure control or aperture-priority auto-exposure. The OM-4 was the first camera with a built-in multi-spot exposure meter (2% of view; 3.3˚ with 50 mm lens) which could take up to eight spot measurements and average them. Another unique feature

1100-497: The actual camera settings. In 1986 the OM-4 was improved to a tougher OM-4Ti (OM-4T in USA) version, with titanium top and bottom plates, improved weatherproofing and high-speed flash sync. This last version was discontinued in 2002. The OM-10 hit the markets in June 1979 at the same time as the OM-2N. The camera was a 35mm focal-plane shutter aperture priority AE SLR camera with an electronic shutter. Only aperture-priority AE

1144-595: The button was placed on the camera body. The OM lens was designed to sit 46 mm (measured from the lens mounting ring, or flange) from the film plane. The combination of on-lens aperture control and the generous ' flange focal distance ' make OM lenses adaptable (with limited functionality) to a variety of other camera systems – including Canon EOS models – by using a mount-specific adapter. (L39,Y48, O56) Screw-in [6–4] [5–4] Screw-in Screw-in Manual Zuiko lenses that were never marketed: Being

1188-429: The camera and photo business, transferring their assets to Sony , who since have continued development of the A system through their Alpha series. When Pentax and Nikon entered the autofocus segment, both used a similar passive array AF system as Minolta, but retained compatibility with their existing manual-focus K and F mounts respectively. Canon , like Minolta, chose to change its mount completely, introducing

1232-513: The camera range from ASA 25 to ASA 1600. Film winding was done by using the film-wind lever located on the top right of the camera. Film rewinding was done manually using the film-rewind crank located at the top left. The camera body measured 136 × 83 × 50 mm and weighed approximately 430 grams (15 oz). The OM-20 (sold in the United States as the OM-G) was essentially a refinement of

1276-620: The compact body size that inspired similar sized SLRs of competing manufacturers (Pentax M series, Nikon FE/FM). Through-the-lens (TTL) off-the-film (OTF) electronic flash control was pioneered by the OM-2 in 1975. The OM-4 and its mechanically controlled companion the OM-3 were quite conservative designs, despite their very sophisticated spot-meters. They can be described as the OM-2 and OM-1 with electronic spot-meter controls grafted on. The OM-4's deliberately limited, but tightly focused, features were not intended to appeal to beginners. Instead of offering every possible automated 'bell and whistle',

1320-491: The high-end models continued, and they were produced until 2002, along with the consumer-grade OM-2000. The Olympus OM-1 was a manually-operated 35 mm single-lens reflex camera forming the basis of the OM system in 1972. At first called the Olympus M-1, Leica disputed this designation and it was changed to OM-1. It was designed by a team led by Yoshihisa Maitani with a through-the-lens exposure meter controlling

1364-562: The integration of electronic flash into the exposure system using the TTL exposure system. 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 system (shared with the OM-4) in addition to the centre-weighted metering of the earlier body. It also featured an LCD similar to the OM-4 which could be illuminated in low light. Its main advantage over

1408-417: The lens, and the setting was electronically displayed on the body and in the viewfinder . The metal housing of older Minolta SLR cameras was replaced with a lighter, cheaper body made of plastics. In other respects, the Maxxum offered most of the standard features of other cameras of the day, with the exception of a rather low flash sync speed (1/125 sec.) and no multi-exposure capability. Minolta introduced

1452-449: The major SLR brands: Olympus, Nikon , Canon , Minolta and Pentax . Between about 1975 and 1985, there was a dramatic shift away from heavy all-metal manual mechanical camera bodies to much more compact bodies with integrated-circuit (IC) electronic automation. In addition, because of rapid advances in electronics, the brands continually leapfrogged each other as they brought out models with new or automated features. The OM-1 introduced

1496-548: The naming pattern with the 'professional' OM-3 and OM-4, and the consumer-level OM-20, OM-30 and OM-40. The cameras were accompanied by a series of Zuiko-branded lenses, as well as a generous selection of accessories. The majority of OM bodies and lenses were manual-focus only; the OM-707 of 1986 was the only true autofocus model. 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

1540-526: The rise of digital SLRs gave Olympus an opportunity to get back into the SLR camera business with its Four Thirds System . The OM-4 is tough and reliable, and regarded as one of the finest SLRs of its generation. Olympus OM-4 Ti appeared in the opening title for the movie Licence to Kill . Olympus OM-4Ti was used by the title character in the 1995 remake of Sabrina (1995 film) with Julia Ormond and Harrison Ford Olympus OM system The Olympus OM System

1584-503: The selection of both the aperture and the shutter speed. An Olympus model made by Cosina , the OM-2000 was not considered by Olympus 'die-hard fans' to be a 'true OM' camera. The OM-2000 had a mechanical, vertical-running shutter in contrast to the traditional OM cameras with their horizontal-running shutter. This allowed the OM-2000 to synchronize an electronic flash at 1/125s. Many photographers found this capability an advantage for

1628-508: The use of "fill flash" in daylight. During development, the Olympus design team led by Yoshihisa Maitani worked on a completely modular set of units called the MDN (Maitani-Darkbox-Normal), which resembled a 35 mm Hasselblad. This camera was built as a prototype, and is sometimes referred to as the OM-X. A more conventional camera which integrated the shutter, film transport, mirror and viewfinder

1672-400: Was a line of 35mm single-lens reflex cameras , lenses and accessories sold by Olympus Corporation between 1972 and 2002. The range was designed by Yoshihisa Maitani , chief designer for Olympus, and his staff; OM stands for Olympus Maitani . The nucleus of the system was a series of compact bodies divided into an advanced series and a later consumer-oriented series. The first model

1716-425: Was available in only one color: all black. The introductory US list price for the body only (no lens) was $ 685. Note that SLRs usually sold for 30 to 40 percent below list price. The camera dimensions are 87 mm height, 139 mm width, 50 mm depth and 540 grams (19 oz) weight. The Olympus OM-series SLRs were influential in SLR design changes in the 1970s and 1980s, with intense competition between

1760-436: Was available with the camera unless the optional manual exposure adapter was installed. This allowed the setting of shutter speeds between 1s and 1/1000s, (bulb mode was also available). The camera was equipped with a fixed pentaprism viewfinder which contained an LED exposure indicator. The finder coverage was measured to be 93%. Exposure control was aperture priority AE using center-weighted light metering . Film speeds of

1804-487: Was called the MDS (Maitani-Darkbox-Simple). The MDS developed into what became the OM-1. The OM Series lenses had the aperture control ring located at the front of the lens barrel. This was done to move it away from the shutter speed control, which was a ring on the camera body concentric with the lens mount. OM lenses also featured a depth-of-field preview button on the lens, in contrast to most other SLR camera systems, in which

1848-470: Was introduced with the OM-4 and, in addition to automatic film advance (up to 5 frames per second), featured motorized film rewind. The camera accepted the Olympus 250-exposure bulk film back (10 meters of film = 250 frames) and the Olympus T-system flashes. The T45 handle-mount electronic flash (guide number 148/45 (feet/meters) at ASA/ISO 100) was also introduced with the OM-4. The original OM-4

1892-411: Was the all-mechanical M-1 which, after pressure from Leica (which already had an M1 model), was renamed OM-1. At the same time the M system was renamed OM System. The camera included a full-aperture TTL Cadmium-sulphide (CdS) exposure meter, and a bayonet lens mount of relatively large diameter. By the end of the 1970s it was joined by the semi-automatic OM-2 and consumer-oriented OM-10. Olympus continued

1936-436: Was the selectable option to assess the darkest or brightest part of the scene, the camera adjusting the exposure based on that measure. The light meter used a dual-concentric segmented silicon photodiode to provide spot or center-weighted readings. It used a graduated, linear LCD shutter speed display at the bottom of the viewfinder to precisely indicate its readings versus the actual camera settings. The major improvements of
