Alpa
Alpa was formerly a Switzerland, Swiss camera design company and manufacturer of 135 film, 35 mm Single-lens reflex camera, 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 (film), 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 135 film, 35mm cameras with a similar high-end but smaller-volume market to Germany's Leica Camera, Leica, Contax, and Rolleiflex. In the late 1930s, Pignons invited engineer Jacques Bogopolsky, Jacques Bolsky to design a camera for them. This he did with the Alpa-Reflex Camera, 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 ...

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 speci ...

Single-lens Reflex 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.

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 format unti ... [...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 ...

Camera
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 cinematog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
