Alpa Racing Cars
Alpa was formerly a Swiss camera design company and manufacturer of 35 mm SLR cameras. The current owners bought the company name after 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 history. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chinon Industries
was a Japanese camera manufacturer. Kodak took a majority stake in the company in 1997, and made it a fully owned subsidiary of Kodak Japan, , in 2004 . As a subsidiary, it continues to develop digital camera models. They manufactured several cameras, such as the CG-5, which was one of the first cameras ever to use an Auto Focus lens, which had to be bought separately. The lenses are now rare. They were cumbersome and had two infrared "eyes" on the top. They would connect by a bayonet fitting similar to the Pentax K fitting, except they also had electrical contacts which would power the motor at the press of the shutter release button. Another popular camera was the CM-1, a basic, fully manual 35 mm SLR camera favored by student amateur photographers because it was cheaper than the rival Pentax K-1000, but could use the same lenses and accessories. The CM-1 featured a battery-powered through-the-lens light metering system that utilized a red-above, green-middle, and red ...

Cameras
A camera is an optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera domain are film, videography, and cinematogr ... [...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 in ...

Carl Zeiss AG
Carl Zeiss AG (), branded as ZEISS, is a German manufacturer of optical systems and optoelectronics, founded in Jena, Germany in 1846 by optician Carl Zeiss. Together with Ernst Abbe (joined 1866) and Otto Schott (joined 1884) he laid the foundation for today's multi-national company. The current company emerged from a reunification of Carl Zeiss companies in East and West Germany with a consolidation phase in the 1990s.

Photokina
Photokina (rendered in the promoters' branding as "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 diffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikon
(, ; ), also known just as Nikon, is a Japanese multinational corporation headquartered in Tokyo, Japan, specializing in optics and imaging products. The companies held by Nikon form the Nikon Group.

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. 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 µm). The residual color error (secondary spectrum) can be up to an order of magnitude less than for an achromat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentax K Mount
The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras. Mounts The Pentax K-mount has undergone a number of evolutions over the years as new functionality has been added. In general, the term K-mount may refer to the original K-mount, or to all its variations. Originally designed by Zeiss for an alliance with Pentax, it was intended to be a common lens mount for a proposed series of cameras and lenses. However, the plan failed to work out and the two firms parted company amicably, but Pentax retained the lens mount and at least one Zeiss lens design for its own use. K-mount The original K-mount is a simple bayonet conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
