Exakta Lens Image 2020-04-20 At 17
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 ...

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 ...

Pentacon
Pentacon is the company name of a camera manufacturer in Dresden, Germany. The name Pentacon is derived from the brand Contax of Zeiss Ikon Kamerawerke in Dresden and Pentagon, as a Pentaprism for Single-Lens Reflex (SLR) cameras was for the first time developed in Dresden. The cross section of this prism has a pentagonal shape. Pentacon is best known for producing the SLR cameras of the Praktica-series as well as the medium format camera Pentacon Six, the Pentacon Super and various cameras of the Exa series. Pentacon also produced slide projectors. History In 1959 several Dresden camera manufacturers, among them VEB Kamerawerke Freital, were joined to create Volkseigener Betrieb Kamera- und Kinowerke Dresden, which was renamed in 1964 to VEB Pentacon Dresden. In 1968, VEB Feinoptisches Werk Görlitz was integrated into VEB Pentacon. Accordingly, the former Meyer-Optik Görlitz lenses were now renamed to ”Pentacon“ .

German Reunification
German reunification (german: link=no, Deutsche Wiedervereinigung) was the process of re-establishing Germany as a united and fully sovereign state, which took place between 2 May 1989 and 15 March 1991. The day of 3 October 1990 when the German Reunification Treaty entered into force dissolving the German Democratic Republic (GDR; german: link=no, Deutsche Demokratische Republik, DDR, or East Germany) and integrating its recently re-established constituent federated states into the Federal Republic of Germany (FRG; german: link=no, Bundesrepublik Deutschland, BRD, or West Germany) to form present-day Germany, has been chosen as the customary ''German Unity Day'' () and has thereafter been celebrated each year from 1991 as a national holiday. East and West Berlin were united into a single city and eventually became the capital of reunited Germany. The East Germany's government led by the Socialist Unity Party of Germany (SED) (a communist party) started to falter on 2 May 1 ...

M42 Lens Mount
The M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. It is more accurately known as the M42 × 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch. (The M42 lens mount should not be confused with the T-mount, which shares the 42mm throat diameter, but differs by having a 0.75mm thread pitch.) It was first used by the East German brands VEB Zeiss Ikon in the Contax S of 1949, and KW in the Praktica of the same year. VEB Zeiss Ikon and KW were merged into the Pentacon brand in 1959, along with several other East German camera makers. M42 thread mount cameras first became well known under the Praktica brand, and thus the M42 mount is known as the Praktica thread mount.The M42 mount is sometimes referred to as a "P" thread. See, e.g., Since there were no proprietary elements to the M42 mount, many other manufacturers used it; this ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stereo
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeaker A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or " ...s (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural recording, Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such ...

Bellows (photography)
In photography, a bellows is the accordion-like, pleated expandable part of a camera, usually a large or medium format camera, to allow the lens to be moved with respect to the focal plane for focusing. Bellows are also used on enlargers. The bellows provides a flexible, dark extension between the film plane and the lens. In some cameras, the photographer can change the angle of the film plate with respect to the optical axis of the lens, providing alterations of perspective distortion and of the object plane of focus. Bellows may be part of a camera or come as an optional accessory. Types Two kinds of bellows are commonly used on cameras; bag bellows are normally used with a lens of short focal length, and accordion bellows with a much longer range of extension. For large format cameras, “double extension” refers to bellows that extend to a length equal to about twice the focal length of a standard lens, e.g. 300 mm for the 4×5 inch format. “Triple extension” ...
