Mamiya Rangefinder Cameras
is a Japanese company that manufactures high-end cameras and other related photographic and optical equipment. With headquarters in Tokyo, it has two manufacturing plants and a workforce of over 200 people. The company was founded in May 1940 by camera designer Seiichi Mamiya () and financial backer Tsunejiro Sugawara. History Mamiya originally achieved fame for its professional medium-format rangefinder film cameras such as the Mamiya Six (1940) and the Mamiya Press (1962) series. It later developed medium-format industry workhorse single lens reflex cameras: Mamiya RB67, RB67 (1970), Mamiya RZ67, RZ67 (1982), and Mamiya 645, 645 (1975); and twin-lens reflex Mamiya C, C series, all of which were used by advanced amateur and professional photographers.

Fishing Reel
A fishing reel is a hand-crank (mechanism), cranked reel used in angling to wind and stow fishing line, typically mounted onto a fishing rod, but may also be used on compound bows or crossbows to retrieve tethered arrows when bowfishing. Modern recreational fishing reels usually have fittings aiding in casting (fishing), casting for distance and accuracy, as well as controlling the speed and tension of line retrieval to avoid line snap and fishing hook, hook dislodgement. Fishing reels are traditionally used for bass fishing in angling and fly casting, competitive casting. They are typically attached near the handle of a fishing rod, though some specialized reels with pressure sensors for immediate retrieval are equipped on downrigger systems which are mounted directly to an ocean-going sport boat's gunwales or transom (nautical), transoms and are used for "deep drop" and trolling (fishing), trolling. The earliest fishing reel was invented in China at least since the Song dynasty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentax
was a Japanese camera and optical equipment manufacturer. Currently, it exists as the Pentax Life Care Business Division of Hoya's medical endoscope business, as well as the digital camera brand of Ricoh Imaging, a subsidiary of Ricoh. Pentax, founded in 1919 as a town workshop specializing in polishing eyeglass lenses, developed Japan's first single-lens reflex camera, the Asahiflex, in 1952. By 2006, Pentax's domestic market share in digital cameras had declined to 4%. In 2007, Pentax was acquired by Hoya and subsequently merged with the company the following year. In 2011, Hoya spun off the Pentax brand's digital camera business, which was then acquired by Ricoh, leading to the establishment of Pentax Ricoh Imaging (current Ricoh Imaging). As a response to growing interest in film photography, Pentax launched the Pentax 17 on June 17, 2024. The Pentax 17 is a half-frame film camera. This launch marks the first Pentax film camera in over two decades. Corporate history ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronica
Bronica also Zenza Bronica (in Japanese: ) was a Japanese manufacturer of classic Medium format (film), medium-format roll film cameras and photographic equipment based in Tokyo, Japan. Their single-lens reflex (SLR) system-cameras competed with Pentax, Hasselblad, Mamiya and others in the medium-format camera market. History Before introduction of the first of what would become a dynasty of Zenza Bronica cameras in 1959, the Romanization of Japanese, Latinized Zenza Bronica name was already a popular Japanese luxury goods brand of the Shinkodo Works (in Japanese: ) since 1947, specialized in the production of intricate crafted and decorated personal accessories, such as metal cigarette lighters and Cigarette case, cases, cosmetic Compact (cosmetics), compacts, and watches, of diverse styles and designs.

Hasselblad
Victor Hasselblad AB is a Sweden, Swedish manufacturer of medium format (film), medium format cameras, photographic equipment and image scanners based in Gothenburg, Sweden. The company originally became known for its classic analog medium-format cameras that used a waist-level viewfinder. Perhaps the most famous use of the Hasselblad camera was during the Apollo program missions when the first humans Moon landing, landed on the Moon. Almost all of the still photographs taken during these missions used modified Hasselblad cameras. In 2016, Hasselblad introduced the world's first digital compact mirrorless medium-format camera, the X1D-50c, changing the portability of medium-format photography. Hasselblad produces about 10,000 cameras a year from a small three-storey building.

Crop Factor
In digital photography, the crop factor, format factor, or focal length multiplier of an image sensor format is the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital cameras, relative to 35 mm film format as a reference. In the case of digital cameras, the imaging device would be a digital image sensor. The most commonly used definition of crop factor is the ratio of a 35 mm frame's diagonal (43.3 mm) to the diagonal of the image sensor in question; that is, \text = \text_ / \text_. Given the same 3:2 aspect ratio as 35mm's 36 mm × 24 mm area, this is equivalent to the ratio of heights or ratio of widths; the ratio of sensor areas is the square of the crop factor. The crop factor is sometimes used to compare the field of view and image quality of different cameras with the same lens. The crop factor is sometimes referred to as the focal length multiplier ("Film") since multiplying a lens f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Units
The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments. The imperial system developed from earlier English units as did the Comparison of the imperial and US customary measurement systems, related but differing system of United States customary units, customary units of the United States. The imperial units replaced the Winchester measure, Winchester Standards, which were in effect from 1588 to 1825. The system came into official use across the British Empire in 1826. By the late 20th century, most nations of the former empire had metrication, officially adopted the metric system as their main system of measurement, but imperial units are still used alongside metric units in the United Kingdom and in some other parts of the former empi ...

120 Film
120 is a film format for still photography introduced by Kodak for their '' Brownie No. 2'' in 1901. It was originally intended for amateur photography but was later superseded in this role by 135 film. 120 film survives to this day as the only medium format film that is readily available to both professionals and amateur enthusiasts. Characteristics The 120 film format is a roll film which is nominally between 60.7 mm and 61.7 mm wide. Most modern films made today are roughly 61 mm (2.4 inches) wide. The film is held in an open spool originally made of wood with metal flanges, later with all-metal, and finally with all-plastic. The length of the film is nominally between and , according to the ISO 732:2000 standard. However, some films may be as short as . The film is attached to a piece of backing paper longer and slightly wider than the film. The backing paper protects the film while it is wound on the spool, with enough extra length to allow loading a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diaphragm (optics)
In optics, a diaphragm is a thin opaque structure with an opening ( aperture) at its center. The role of the diaphragm is to ''stop'' the passage of light, except for the light passing through the ''aperture''. Thus it is also called a stop (an aperture stop, if it limits the brightness of light reaching the focal plane, or a field stop or flare stop for other uses of diaphragms in lenses). The diaphragm is placed in the light path of a lens or objective, and the size of the aperture regulates the amount of light that passes through the lens. The centre of the diaphragm's aperture coincides with the optical axis of the lens system. Most modern cameras use a type of adjustable diaphragm known as an iris diaphragm, and often referred to simply as an iris. See the articles on aperture and f-number for the photographic effect and system of quantification of varying the opening in the diaphragm. Iris diaphragms versus other types A natural optical system that has a diaphra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shutter Priority
Shutter priority (usually denoted as S on the mode dial), also called time value (abbreviated as Tv), refers to a setting on cameras that allows the user to choose a specific shutter speed while the camera adjusts the aperture to ensure correct Exposure (photography), exposure. This is different from manual mode, where the user must decide both values, aperture priority where the user picks an aperture with the camera selecting the shutter speed to match, or program mode where the camera selects both. Background Shutter priority with longer exposures is chosen to create an impression of motion. For example, a waterfall will appear blurred and fuzzy. If the camera is panned with a moving subject, the background will appear blurred. When photographing sports or high-speed phenomena, shutter priority with short exposures can ensure that the motion is effectively ''frozen'' in the resulting image. Like aperture priority, this mode allows for partial automation thus decreasing the ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 shu ...
