Alpa
Alpa was formerly a Swiss camera design company and manufacturer of 35 mm SLR cameras. The current owners bought the company name after the bankruptcy of the original company and the company exists today as a designer and manufacturer of high-end medium-format camerasWebsite alpa.ch. History Alpa was an offshoot of the Pignons S.A. company, which made a particular part (pinions) for Swiss watches. They made high-end, all-metal 35mm cameras with a similar high-end but smaller-volume market to Germany's Leica, Contax, and Rolleiflex. In the late 1930s, Pignons invited engineer Jacques Bolsky to design a camera for them. This he did with the Alpa-Reflex in the 1940s. In true Swiss fashion, each camera was individually crafted. Thus, production was low, but quality and prices were high. Even these days, collectible Alpa cameras can fetch quite a high auction price. It is estimated that as few as 40,000 cameras of all models of Alpa were made during the company's 40-year hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alpa-Reflex Camera
The 35mm SLR camera Alpa-Reflex has its origins back in the 1930s when a Swiss precision mechanical manufacturer decided to diversify their product range, having mainly relied on manufacturing parts for the watch industry. They sought outside assistance and by 1939 the plans were ready and building cameras commenced at a very slow rate. The camera was eventually named the Alpa because it was light, pocketable, and might easily be brought along travelling in the Alps. The Alpa-Reflex is only predated by the Kine Exakta, the Sport, and the Praktiflex 35mm SLRs. The manufacturer was Pignons S.A, Ballaigues, and the designer was Jacques Bolsky born December 31, 1895, in Kiev as Yakob Bogopolsky. He emigrated to the United States of America once the design was completed. He was also the inventor of the renowned Bolsey and Bolex cine cameras. Camera production Pignons S.A. never aimed at producing cameras in large quantities, but rather at quality and they often made cameras to spe ...

Jacques Bogopolsky
Jacques Bogopolsky (also Jacques Boolsky or Jacques Bolsey; born Yakov Bogopolsky; December 31, 1895, Kiev, Kiev Governorate, Russian Empire – January 20, 1962, Long Island) was an engineer and camera designer. Early life He was born into a Jewish family. Career He was an inventor of movie cameras. The brand name Bolex comes from his name. He was also instrumental in the initial design of the Alpa-Reflex Camera 35mm single-lens reflex camera that later was developed into the Alpa cameras. Bolsey Camera Company In 1947, Jacques Bolsey founded ''Bolsey Camera Company'', after making cameras for US military during WW2, making the Bolsey B, a consumer 35mm, similar to the mil-spec devices. In 1956, the company closed, when Bolsey sold to Wittnauer. 35mm rangefinder * Bolsey B (1947-1949) * Bolsey B2 (1949-1956) * Bolsey B22 (1953-1956) * Bolsey Jubilee (1955-1956) * Bolsey B3 (1956) * Wittnauer Festival (1957), sold by Wittnauer 35mm TLR + rangefinder * Bolsey C (1950- ...

Single-lens Reflex Camera
In photography, a single-lens reflex camera (SLR) is a type of camera that uses a mirror and prism system to allow photographers to view through the lens and see exactly what will be captured. SLRs became the dominant design for professional and consumer-level cameras throughout the late 20th century, offering interchangeable lenses, through-the-lens (TTL) metering, and precise framing. Originating in the 1930s and popularized in the 1960s and 70s, SLR technology played a crucial role in the evolution of modern photography. Although digital single-lens reflex (DSLR) cameras succeeded film-based models, the rise of Mirrorless camera, mirrorless cameras in the 2010s has led to a decline in SLR use and production. 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 and allows light to pass through to the light receptor and the im ...

Medium Format (film)
Medium format has traditionally referred to a film format in photography and the related cameras and equipment that use film. Nowadays, the term applies to film and digital cameras that record images on media larger than the used in 35 mm photography (though not including 127 sizes), but smaller than (which is considered large format photography). In digital photography, medium format refers either to cameras adapted from medium-format film photography uses or to cameras making use of sensors larger than that of a 35 mm film frame. Some of the benefits of using medium-format digital cameras include higher resolution sensors, better low-light capabilities compared to a traditional 35mm DSLR, and a wider dynamic range. Characteristics Medium-format cameras made since the 1950s are generally less automated than smaller cameras made at the same time. For example, autofocus became available in consumer 35 mm cameras in 1977, but did not reach medium forma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Photographic Equipment Makers
This list of photographic equipment makers lists companies that manufacture (or license manufacture from other companies) equipment for photography. Camera and lens manufacturers Note that producers whose only presence in the photo industry at any time has been the manufacture of digital cameras ( Logitech, for example, which has made Webcams) are listed separately on the List of digital camera brands. There is not a very clear distinguishing line between camera producers and lens producers; many companies do both, or have done both at one time or another. Some camera manufacturers sell lenses made by others as their own, in an OEM arrangement. Some camera makers design lenses but outsource manufacture. Some lens makers have cameras made to sell under their own brand name. A few companies are only in the lens business. Some camera companies make no lenses, but usually at least sell a lens from some lens maker with their cameras as part of a package. Note that many optical i ...

Apochromat
An apochromat, or apochromatic lens (apo), is a photographic or other lens that has better correction of chromatic and spherical aberration than the much more common achromat lenses. The prefix ''apo-'' comes from the Greek preposition ''ἀπό-'', meaning free from or away from. Explanation Chromatic aberration is the phenomenon of different colors focusing at different distances from a lens. In photography, chromatic aberration produces soft overall images, and color fringing at high-contrast edges, like an edge between black and white. Astronomers face similar problems, particularly with telescopes that use lenses rather than mirrors. ''Achromatic'' lenses are corrected to bring ''two'' wavelengths into focus in the same plane – typically red (~0.590 μm) and blue (~0.495 μm). ''Apo''chromatic lenses are designed to bring ''three'' colors into focus in the same plane – typically red (~0.620 μm), green (~0.530 μm), and blue (~0.465 μ ...

Cameras
A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century. Cameras function through a combination of multiple mechanical components and principles. These include exposure control, which regulates the amount of light reaching the sensor or film; the lens, which focuses the light; the viewfinder, which allows the user to preview the scene; and the film or sensor, which captures the image. Several types of camera exist, each suited to specific uses and offering unique cap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodenstock Photo Optics
Rodenstock Photo Optics traces its origins to a mechanical workshop founded in 1877 by Josef Rodenstock and his brother Michael in Würzburg, Germany. The company relocated to Munich by 1884 and became an important manufacturer of both corrective lenses for glasses and camera lenses by the early 1900s. These two lines began to diverge in the 1960s as the center of photographic lens manufacturing shifted to Japan; the ophthalmic business continued as Rodenstock GmbH while the remaining camera lens business was repositioned to serve the large format and industrial precision optics markets, then spun off in 1996 as Rodenstock Präzisionsoptik. Since then, the precision optics brand has been acquired in succession by LINOS Photonics (Göttingen, 2000), Qioptiq Group (Luxembourg, 2006), and Excelitas Technologies (2013). Photographic lenses produced by Rodenstock during and since the 20th century include the brands ''Ysarex'', ''Heligon'', ''Eurygon'', ''Rotelar'', ''Apo-Ronar'', ''Ro ...

Photokina
Photokina is a trade fair held in Europe for the photographic and imaging industries. It is the world's largest such trade fair. The first Photokina was held in Cologne, Germany, in 1950, and since 1966 it has been held biennially in September at the Koelnmesse Trade Fair and Exhibition Centre in Deutz. The final Photokina under the then-current biennial cycle took place in 2018. Initially, the promoters planned to start a new annual cycle in 2019, with future shows to be held in May, but they later decided not to begin the new annual cycle until 2020. The worldwide outbreak of the Coronavirus disease 2019 and its effect on the imaging industry made Koelnmesse decide to cancel both Photokina 2020 and Photokina 2021. Many photographic and imaging companies introduce and showcase state of the art imaging products at Photokina. Similar trade shows The show has two main competitors, both of which are annual shows held in different parts of the world. The CP+ show in Yokohama, J ...
