History Of The Single-lens Reflex Camera
The history of the single-lens reflex camera (SLR) begins with the use of a reflex mirror in a camera obscura described in 1676, but it took a long time for the design to succeed for photographic cameras. The first patent was granted in 1861, and the first cameras were produced in 1884, but while elegantly simple in concept, they were very complex in practice. One by one these complexities were overcome as optical and mechanical technology advanced, and in the 1960s the SLR camera became the preferred design for many high-end camera formats. The advent of digital point-and-shoot cameras in the 1990s through the 2010s with LCD viewfinder displays reduced the appeal of the SLR for the low end of the market. The mirrorless interchangeable-lens camera is increasingly challenging the mid-price range market. But the SLR remains the camera design of choice for most professional and ambitious amateur photographers. Early large and medium format SLRs The photographic single-lens reflex ...

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.

35 mm Format
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film used for still photography. It is a film with a film gauge of loaded into a standardized type of magazine – also referred to as a cassette or cartridge – for use in 135 film cameras. The engineering standard for this film is controlled by ISO 1007 titled '135-size film and magazine'. The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 828, 126, 110, and APS, it remains the most popular film size today. The size of the 135 film frame with its aspect ratio of 1:1.50 has been adopted by many high-end digital single-lens reflex and digital mirrorless cameras, commonly referred to as "full frame".

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. ZEISS is active in four business segments with approximately equal revenue (Industrial Quality and Research, Medical Technology, Consumer Markets and Semiconductor Manufacturing Technology) in almost 50 countries, has 30 production sites and around 25 development sites worldwide. Carl Zeiss AG is the holding of all subsidiaries within Zeiss Group, of which Carl Zeiss Meditec AG is the only one that is traded at the stock market. Carl Zeiss AG is owned by the foundation Carl-Zeiss-Stiftung. The Zeiss Group has its headquarters in southern Germany, in the smal ...

Exakta
The Exakta (sometimes Exacta) was a camera produced by the ''Ihagee Kamerawerk'' in Dresden, Germany, founded as the Industrie und Handels-Gesellschaft mbH, in 1912. The inspiration and design of both the VP Exakta and the Kine Exakta are the work of the Ihagee engineer Karl Nüchterlein (see Richard Hummel's Spiegelreflexkameras aus Dresden), who did not survive the Second World War. An Exakta VX was used by James Stewart's character, a professional photographer, to spy on his possibly murderous neighbor in Alfred Hitchcock's ''Rear Window''. Characteristics Highlights of Exakta cameras include: * First single-lens reflex camera (SLR) for 127 roll film (VP Exakta) came in 1933 * First wind-on lever in 1934 * First built-in flash socket, activated by the shutter, in 1935 * First SLR for 35mm film came in 1936, the Kine Exakta Early Kine Exaktas had a fixed waist-level viewfinder, but later models, starting with the Exakta Varex, had an interchangeable waist- or eye-level fin ...

Kine Exakta
The Kine Exakta was the first 35mm single-lens reflex (SLR) still camera in regular production. It was presented by Ihagee Kamerawerk Steenbergen GmbH, Dresden at the Leipziger Frühjahrsmesse in March 1936. The Exakta name had already been used by Ihagee on a roll film rangefinder RF camera line since 1933, among these the ''Vest Pocket Exakta Model B'' from which the Kine Exakta inherited its general layout and appearance. The word Kine (cine, cinema, movie film) never appeared on the camera itself, only in the instruction manuals and advertising to distinguish it from the roll film variants. Several of its features constituted the foundation for the majority of ''35mm'' SLR cameras produced ever since, although at this stage in a relatively primitive state. The perforated ''35mm film'' had been used in miniature cameras for more than two decades using the '' 24x36mm negative format''. The single lens reflex principle is even older and was widely used in cameras for the medium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rectaflex
Rectaflex was the world's first series produced Pentaprism single lens reflex camera. It was produced from 1948 to 1958. Rectaflex was the only Italian single-lens reflex camera ever built. There has been some uncertainty about the Rectaflex being first or second pentaprism SLR to be produced. Marco Antonettos very thorough research in 2002 clarified that the Rectaflex was the first. Original Rectaflex The Rectaflex was a 35mm SLR camera with a Focal-plane shutter, interchangeable lenses and a pentaprism eye-level finder. It was the world's first SLR equipped with a pentaprism, with a final presentation in April 1948, and start of series production in September the same year, thus hitting the market one year before the Contax S Contax (stylised as CONTAX in the Kyocera era) began as a German camera model in the Zeiss Ikon line in 1932, and later became a brand name. The early cameras were among the finest in the world, typically featuring high quality Zeiss intercha ..., ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Light Meter
A light meter is a device used to measure the amount of light. In photography, a light meter (more correctly an exposure meter) is used to determine the proper exposure for a photograph. The meter will include either a digital or analog calculator which displays the correct shutter speed and f-number for optimum exposure, given a certain lighting situation and film speed. Similarly, exposure meters are also used in the fields of cinematography and scenic design, in order to determine the optimum light level for a scene. Light meters are used in the general field of architectural lighting design to verify proper installation and performance of a building lighting system, and in assessing the light levels for growing plants. Use in photography The earliest type of light meters were called ''extinction meters'' and contained a numbered or lettered row of neutral density filters of increasing density. The photographer would position the meter in front of his subject and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
