Olympus OM-D E-M5
The Olympus OM-D E-M5, announced in February 2012, is a Micro Four Thirds compact mirrorless interchangeable lens camera. In style and name it references the Olympus OM series of film SLR cameras, but it is not an SLR camera (there is no optical path from lens to viewfinder: a high quality electronic viewfinder is used). The successor is the Olympus OM-D E-M5 Mark II. Awards In April 2012, the enthusiast photography web site Digital Photography Review (DP Review) awarded the OM-D EM-5 a Gold Award. On the same website it was subsequently voted Best Camera of 2012 in a photographers' poll. Other photography news and reviews websites that awarded the OM-D EM-5 "Camera of the Year" for 2012 were ''photographyblog.com'' and ''wirefresh''. The camera also won a 2012 Pop Photo award from the magazine ''Popular Photography''. Features * Magnesium alloy body with extensive weather sealing * Up to ISO 25,600 * 16 MP Four Thirds sensor, with substantially lower noise than the earlier ...

Olympus Cameras
is a Japanese manufacturer of optics and reprography products. Olympus was established on 12 October 1919, initially specializing in microscopes and thermometers. Olympus holds roughly a 70-percent share of the global endoscope market, estimated to be worth approximately US$2.5 billion. Its global headquarters are located in Shinjuku, Tokyo, Japan. In 2011, Olympus attracted worldwide media scrutiny when it fired its CEO and the matter snowballed into a corporate corruption investigation with multiple arrests. It paid $646 million in kickback fines in 2016. Products Cameras and audio In 1936, Olympus introduced its first camera, the Semi-Olympus I, fitted with the first Zuiko-branded lens. The Olympus Chrome Six was a series of folding cameras made by Takachiho, and later Olympus, from 1948 to 1956, for 6×4.5 cm or 6×6 cm exposures on 120 film. The first innovative camera series from Olympus was the Pen, launched in 1959. It used a half-frame format, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympus OM
The Olympus OM System was a line of 35mm single-lens reflex cameras, lenses and accessories sold by Olympus between 1972 and 2002. The system was introduced by Olympus in 1972. 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 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 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 ...

Bulb (photography)
The Bulb setting (abbreviated B) on camera shutters is a momentary-action mode that holds shutters open for as long as a photographer depresses the shutter-release button. The Bulb setting is distinct from shutter's Time (T) setting, which is an alternate-action mode where the shutter opens when the shutter-release button is pressed and released once, and closes when the button is actuated again. History Decades before the first flashbulbs, some box cameras and many view cameras and folding cameras came with a detachable pneumatic shutter release with a rubber bulb on the end; "Bulb" refers to the rubber shutter release bulb. Though mechanically timed exposures could also be triggered by squeezing the shutter release bulb, "Bulb" exposures then had the same momentary action as camera shutters have today, as per this description from Sears Roebuck's 1909 ''Cameras Photographic Supplies'': Around 1894 in Germany, the momentary-action setting on camera shutters made by C. A. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contrast Detection Autofocus
An autofocus (or AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished as active, passive or hybrid types. Autofocus systems rely on one or more sensors to determine correct focus. Some AF systems rely on a single sensor, while others use an array of sensors. Most modern SLR cameras use through-the-lens optical sensors, with a separate sensor array providing light metering, although the latter can be programmed to prioritize its metering to the same area as one or more of the AF sensors. Through-the-lens optical autofocusing is usually speedier and more precise than manual focus with an ordinary viewfinder, although more precise manual focus can be achieved with special accessories such as focusing magnifiers. Autofocus accura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Stabilisation
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation. It is mainly used in high-end image-stabilized binoculars, still and video cameras, astronomical telescopes, and also smartphones. With still cameras, camera shake is a particular problem at slow shutter speeds or with long focal length lenses (telephoto or zoom). With video cameras, camera shake causes visible frame-to-frame jitter in the recorded video. In astronomy, the problem of lens shake is added to variation in the atmosphere, which changes the apparent positions of objects over time. Application in still photography In photography, image stabilization can facilitate shutter speeds 2 to 5.5 stops slower (exposures 4 to times ...

Popular Photography
''Popular Photography'', formerly known as ''Popular Photography & Imaging'', also called ''Pop Photo'', is a monthly American consumer website and former magazine that at one time had the largest circulation of any imaging magazine, with an editorial staff twice the size of its nearest competitor. Although the magazine ceased publication in early 2017, PopPhoto had a soft relaunch as a web-only publication the following year, and an official relaunch in December 2021. History The first issue of ''Popular Photography'' was published in 1937. It was based in New York City and owned by a number of companies during its lifetime, including Ziff Davis. It was sold by Hachette Filipacchi Media U.S. to Bonnier Corporation in 2009. The magazine's last publisher was Steven B. Grune and its last editor-in-chief was Miriam Leuchter. One of its most well-known editors was American photographer and writer Norman Rothschild, whom Edward Steichen Edward Jean Steichen (March 27, 1879 – Mar ...

Olympus OM-D E-M5 Mark II
The Olympus OM-D E-M5 Mark II is a digital interchangeable-lens camera announced in February 2015. It features a new 40-megapixel high-resolution mode that uses sensor shift to generate overlapping 16-megapixel images to then compute a 40-megapixel composite. It is the successor of the Olympus OM-D E-M5 The Olympus OM-D E-M5, announced in February 2012, is a Micro Four Thirds compact mirrorless interchangeable lens camera. In style and name it references the Olympus OM series of film SLR cameras, but it is not an SLR camera (there is no optical .... Compared to that earlier model from 2012 and flagship OM-D E-M1 released in 2013, both of which are claimed to have 4 f-stops of shake compensation when shooting handheld, Olympus claims the OM-D E-M5 II can compensate 5 f-stops. New significant features * Improved five-axis stabilization which can compensate shaking in handheld shot by 5 stops * FullHD video recording at 24p, 25p, 30p, 50p, and 60p with up to 77-Mbit/s bitrates ...

SLR Camera
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.
