Kodak Instamatic Reflex
The Kodak Retina Reflex is a discontinued series of four single-lens reflex cameras made by Kodak, continuing the brand Kodak Retina. Retina Reflex The Kodak Type 025 Retina Reflex is an SLR camerawith so-called convertible lenses (German: Wechselobjektiv), interchangeable lens componentsmade by Kodak AG Stuttgart, Germany. It was made between Spring 1957 and October 1958. Like many 35 mm SLR cameras of West German heritage it works with a leaf shutter instead of a focal plane shutter. It was named Type 025 Retina Reflex since it inherited several features from the Retina rangefinder cameras, like the Retina IIIc: The film advance and exposure counting system, the film channel, the selenium meter, and the focusing mechanics of the lenses. Even the Synchro- Compur shutter is very similar to the earlier designs. The early Retina reflex models are basically fixed-lens cameras with interchangeable front elements. Later models had fully interchangeable lenses. In the first mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convertible Lens
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically. There is no major difference in principle between a lens used for a still camera, a video camera, a telescope, a microscope, or other apparatus, but the details of design and construction are different. A lens might be permanently fixed to a camera, or it might be interchangeable with lenses of different focal lengths, apertures, and other properties. While in principle a simple convex lens will suffice, in practice a compound lens made up of a number of optical lens elements is required to correct (as much as possible) the many optical aberrations that arise. Some aberrations will be present in any lens system. It is the job of the lens designer to balance these and produce a design ...

Kodak Retina IIC
Retina was the brand-name of a long-running series of German-built Kodak 35mm cameras, produced from 1934 until 1969. Kodak Retina cameras were manufactured in Stuttgart-Wangen by the Kodak AG Dr. Nagel Werk which Kodak had acquired in December 1931. The Retina line included a variety of folding and non-folding models, including the Retina Reflex single lens reflex camera. Retina cameras were noted for their compact size, high quality, and low cost compared to competitors. These cameras retain a strong following today, of both photographers and collectors. Kodak AG also offered a companion line of less-expensive Retinette cameras, with similar looks and function. History August Nagel was a prolific camera designer and entrepreneur who was one of the founders of Zeiss Ikon, when he merged his company, Contessa-Nettel AG, with Zeiss and others to form that group in 1919. As well as being an owner he was an active designer of fine Zeiss cameras including miniatures. He lef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentaprism
A pentaprism is a five-sided reflecting prism used to deviate a beam of light by a constant 90°, even if the entry beam is not at 90° to the prism. The beam reflects inside the prism ''twice'', allowing the transmission of an image through a right angle without inverting it (that is, without changing the image's handedness) as an ordinary right-angle prism or mirror would. The reflections inside the prism are not caused by total internal reflection, since the beams are incident at an angle less than the critical angle (the minimum angle for total internal reflection). Instead, the two faces are coated to provide mirror surfaces. The two opposite transmitting faces are often coated with an antireflection coating to reduce spurious reflections. The fifth face of the prism is not used optically but truncates what would otherwise be an awkward angle joining the two mirrored faces. In cameras A variant of this prism is the roof pentaprism which is commonly used in the viewfinder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Retina Reflex Mg 3808
The retina (from la, rete "net") is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs. The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception. The retina serves a function which is in many ways analogous to that of the film or image sensor in a camera. The neural retina consists of several layers of neurons interconnected by synapses and is supported by an outer layer of pigmented epithelial cells. The primary light-sensing cells in the retina are the photoreceptor cells, which are of two types: rods and cones. Rods function mainly in dim light and provide monochromatic vision. Cones function in well-lit conditions and are responsible for the perception of colour through the use of a range of opsins, as well as high-acuity vision used for tasks ...

Schneider Kreuznach
Schneider Kreuznach () is the abbreviated name of the company Jos. Schneider Optische Werke GmbH, which is sometimes also simply referred to as Schneider.

Voigtländer
Voigtländer () was a significant long-established company within the optics and photographic industry, headquartered in Braunschweig, Germany, and today continues as a trademark for a range of photographic products. History Voigtländer was founded in Vienna, Archduchy of Austria, in 1756, by . Voigtländer produced mathematical instruments, precision mechanical products, optical instruments, including optical measuring instruments and opera glasses, and is the oldest name in cameras. Early beginnings Johann Christoph Voigtländer (November 19, 1732 in Leipzig – June 27, 1797 in Vienna), the son of a carpenter, came to Prague in 1755, and to Vienna in the same year, and worked from 1757 to 1762 in the workshop of Meinicke, who produced mathematical instruments. Through Johann Voigtländer's skilful achievements, the Minister of State of the Habsburg monarchy— Prince Wenzel von Kaunitz, drew attention to Voigtländer and Empress Maria Theresa of Austria granted Voigtlän ...

Carl Braun Camera-Werke
Carl Braun Camera-Werk of Nuremberg, Germany, or Braun, as it was more commonly called, was founded as an optical production house. It is best known for its 35mm film cameras named Paxette, and for slide projectors named Paximat. History The company was founded in 1915 under name of ''Karl Braun KG, Fabrik optischer Geräte und Metallwaren'' for the fabrication of optical appliances and metalware. In 1948, the company began producing box film cameras, in rollfilm and 35mm format. It changed its name to ''Carl Braun Camera-Werke''. Its best known model was the Paxette series of 35mm rangefinder cameras. Most of the company's cameras were consumer-level models, though the company did briefly produce several more advanced 35mm rangefinder designs as well as an interesting 35mm single-lens reflex camera line with leaf shutters, the Paxette Reflex (Automatic?)/AMC M335 Reflex. The most advanced of Braun's rangefinders and SLRs had interchangeable lenses. Braun ceased making cameras i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deckel
Friedrich Deckel GmbH, also known as F.Deckel, was a German company founded by Friedrich Deckel and Christian Bruns in Munich as Bruns & Deckel in 1903. Its most famous product is the ''Compur'' line of leaf shutters used on many photographic lenses starting from 1911. Bruns and Deckel previously had worked together at C. A. Steinheil & Söhne; Bruns was an inventor responsible for developing leaf shutters while Deckel was a laboratory mechanic. Corporate history By 1910, Zeiss had acquired a 16.8% stake in F.Deckel. Zeiss also owned a significant portion of competitor (AGC), which was later renamed Prontor after its competing leaf shutter. Taking advantage of their growing knowledge of factory production methods and machinery, by about 1920 Deckel started producing "extra" machines for sale to the trade, most notably the versatile ''FP'' line of industrial milling machines. During World War II, photographic equipment production was paused and F.Deckel made fuel pumps for BM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
