Olympus OM-2
The Olympus OM-2 is a single-lens reflex film system camera produced by Olympus of Japan. Main features The Olympus OM-2 is an aperture-priority automatic-exposure camera (with full manual operation selected via switch), based on the earlier, successful Olympus OM-1 body. The OM-2 was introduced in 1975, and combined the light, sturdy camera body style of the manual-only OM-1 with a new automatic exposure system. One of the main selling points of the OM-2 was that all of the OM-1 accessories and lenses would fit without modification, offering a compact system and an easy upgrade path for OM-1 owners. Although the camera was promoted in photography publications and magazines as technically superior, Olympus as a company did not have the same recognition as Nikon or Canon and, as a result, some professionals considered the cameras inferior due to their lighter weight. Despite this a number used the OM-2 including Patrick Lichfield, Kon Sasaki, Roy Morsch, Jacques Schumacher, Robert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
135 Film
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film used for still photography. It is a film with a film gauge of loaded into a standardized type of magazine – also referred to as a cassette or cartridge – for use in 135 film cameras. The engineering standard for this film is controlled by ISO 1007 titled '135-size film and magazine'. The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 828, 126, 110, and APS, it remains the most popular film size today. The size of the 135 film frame with its aspect ratio of 1:1.50 has been adopted by many high-end digital single-lens reflex and digital mirrorless cameras, commonly referred to as " full frame".

Olympus OM-1
The Olympus OM-1 is a manually operated 35mm single-lens reflex camera. It is part of the Olympus OM system. History The first model was presented at photokina in Cologne in 1972 and was called the Olympus M-1. Thirteen years earlier, the release of the Nikon F had made the 35 mm SLR the standard choice for professionals accustomed to Leica and other rangefinders, but it had driven the market towards heavy and bulky cameras. The Olympus M-1 changed this and with it began a reduction of size, weight and noise of the 35 mm SLRs. It was designed by a team led by Yoshihisa Maitani, who had already created the Pen and Pen F cameras, noted for their compactness. Since Leica's flagship rangefinder cameras are known as the M Series, Leica complained about the name of the M-1, forcing Olympus to rename it as the OM-1 to further clarify between the brands. Because of this, today bodies and lenses with the original M name are rare (52000 bodies were made according to Olympus) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympus OM-4
The Olympus OM-4 is an interchangeable-lens, 35 mm film, single lens reflex (SLR) camera; manufactured by Olympus Optical Co., Ltd. (today Olympus Corporation) in Japan, and sold as OM-4 from 1983 to 1987 and as OM-4Ti from 1986 to 2002. History 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. Features The OM-4 used 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-mounte ...

Hot Shoe
Canon EOS 350D Hot shoe Proprietary hot shoe used by Minolta and older Sony cameras (Konica Minolta Maxxum 7D">Sony.html" ;"title="Minolta and older Sony">Minolta and older Sony cameras (Konica Minolta Maxxum 7D) A hot shoe is a mounting point on the top of a camera to attach a flash (photography), flash unit and other compatible accessories. It takes the form of an angled metal bracket surrounding a metal contact point which completes an electrical connection between camera and accessory for standard, brand-independent flash synchronization. The hot shoe is a development of the standardised "accessory shoe", with no flash contacts, formerly fitted to cameras to hold accessories such as a rangefinder, or flash connected by a cable. The dimensions of the hot shoe are defined by the International Organization for Standardization in ISO 518:2006. Details such as trigger voltage are not standardised; electrical incompatibilities are still possible between brands. Design The h ...

Exposure (photography)
In photography, exposure is the amount of light per unit area (the image plane's illuminance times the exposure time) reaching a frame of photographic film or the surface of an electronic image sensor, as determined by shutter speed, lens F-number, and scene luminance. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region. An "exposure" is a single shutter cycle. For example, a long exposure refers to a single, long shutter cycle to gather enough dim light, whereas a multiple exposure involves a series of shutter cycles, effectively layering a series of photographs in one image. The accumulated ''photometric exposure'' (''H''v) is the same so long as the total exposure time is the same. Definitions Radiant exposure Radiant exposure of a ''surface'', denoted ''H''e ("e" for "energetic", to avoid confusion with photometric quantities) and measured in , is given by :H_\mathrm = E_\mathrmt, where *''E'' ...

Flash (photography)
A flash is a device used in photography that produces a brief burst of light (typically lasting 1/1000 to 1/200 of a second) at a color temperature of about 5500 K to help illuminate a scene. A major purpose of a flash is to illuminate a dark scene. Other uses are capturing quickly moving objects or changing the quality of light. ''Flash'' refers either to the flash of light itself or to the electronic flash unit discharging the light. Most current flash units are electronic, having evolved from single-use flashbulbs and flammable powders. Modern cameras often activate flash units automatically. Flash units are commonly built directly into a camera. Some cameras allow separate flash units to be mounted via a standardized accessory mount bracket (a ''hot shoe''). In professional studio equipment, flashes may be large, standalone units, or studio strobes, powered by special battery packs or connected to mains power. They are either synchronized with the camera using a flas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auto Dynamic Metering
In photography, through-the-lens metering (TTL metering) refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the photographic lens, lens; as opposed to using a separate metering window or external hand-held light meter. In some cameras various TTL metering modes can be selected. This information can then be used to set the optimal Photographic film, film or image sensor exposure (photography), exposure (Zone System, average luminance), it can also be used to control the amount of light emitted by a flash (photography), flash unit connected to the camera. Description Through-the-lens metering is most often associated with single-lens reflex camera, single-lens reflex (SLR) cameras. In most film and digital SLRs, the light sensor(s) for exposure metering are incorporated into the pentaprism or pentamirror, the mechanism by which a SLR allows the viewfinder to see directly through the lens. As the mirror is flipped up, no light can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kon Sasaki
Born on November 2nd 1918 in Tsingtao, China, Sasaki took an in interest in photography after purchasing a Togo camera in 6th grade. He continued to take photos during his military service being stationed at Pyongyang, Manchuria, and Manchukuo before returning to Kobe in 1942. He would work as a photojournalist and freelance photographer before meeting Ihei Kimura in 1951 and would later move to Tokyo as his apprentice in 1960. Sasaki was reportedly told, "You'll go bad if you keep photographing bras. Come over to Tokyo." Accepting Kimura's invitation, he left his photo studio to a friend, sold all his camera gear, and bought a Leica M3. As a photojournalist he covered social issues including heroin addiction, gradeschool dropouts, and prostitution. He began publishing regularly on Asahi Camera in 1966, renowned for his macro work on flowers, insects, and small animals. 256 of his photos were published on the magazine across 23 years with his specialty being newborn life and th ...

Aperture-priority
Aperture priority, often abbreviated ''A'' or ''Av'' (for aperture value) on a camera mode dial, is a mode on some cameras that allows the user to set a specific aperture value (f-number) while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by the camera's light meter. This is different from manual mode, where the user must decide both values, shutter priority where the user picks a shutter speed with the camera selecting an appropriate aperture, or program mode where the camera selects both. Uses Depth of field As an image's depth of field is inversely proportional to the size of the lens's aperture, aperture priority mode is often used to allow the photographer to control the focus of objects in the frame. Aperture priority is therefore useful in landscape photography, for example, where it may be desired that objects in foreground, middle distance, and background all be rendered crisply, while shut ...
