Instamatic Reflex
The Kodak Retina Reflex is a discontinued series of four single-lens reflex cameras made by Kodak in Germany between 1957 and 1974, as part of the Kodak Retina line of 35mm film cameras. Overview The earliest Retina Reflex (Type 025, 1957) uses the convertible lens system introduced with the Kodak Retina IIc/IIIc in 1954. The successor cameras, starting with the Retina Reflex S (Type 034, 1959), use DKL-mount lenses, introduced with the Retina IIIS of 1958. The Retina Reflex brand was discontinued in 1966, then revived as the Instamatic Reflex in 1968, using the same DKL-mount lenses with the easy-loading ''Kodapak'' line of 126 film cartridges. The Instamatic Reflex was discontinued in 1974. Convertible lens camera Retina Reflex The Kodak Type 025 Retina Reflex is an SLR camera that uses convertible lenses (German: Wechselobjektiv), made by Kodak Stuttgart, Germany. It was made between Spring 1957 and October 1958. Like many 35 mm SLR cameras of West German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convertible Lens
A camera lens, photographic lens or photographic objective is an optical lens or assembly of lenses (compound lens) 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 desig ...

Contaflex (SLR)
The Contaflex series is a family of 35mm format, 35mm Single-lens reflex cameras (SLR) equipped with a leaf shutter, produced by Zeiss Ikon in the 1950s and 1960s. The name was first used by Zeiss Ikon in 1935 for a 35mm Twin-lens reflex camera, the ''Contaflex TLR''; for the earlier TLR, the -flex suffix referred to the integral reflex mirror for the viewfinder. The first SLR models, the Contaflex I and II (introduced in 1953) have fixed lenses, while the later models have interchangeable lenses; eventually the Contaflexes became a camera system with a wide variety of accessories. History The ''Mecaflex'' was presented at photokina 1951 and launched two years later as one of the first SLRs, fitted with a leaf shutter behind the removable lens and a waist-level viewfinder with a reflex mirror that swings out of the way during the film exposure. Compared to twin-lens reflex cameras, the SLR offered several advantages: photographer would be able to view the scene exactly through the ...

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 ... [...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 BMW ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kodak Retina IIIS
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] |

Close-up Lens
In photography, a close-up lens (sometimes referred to as ''close-up filter'' or a ''macro filter'') is a simple secondary lens used to enable macro photography without requiring a specialised primary lens. They work like reading glasses, allowing a primary lens to focus more closely. Bringing the focus closer allows the photographer more possibilities. Close-up lenses typically mount on the filter thread of the primary lens, and are often manufactured and sold by suppliers of photographic filters. Nonetheless, they are lenses and not photographic filter, filters. Some manufacturers refer to their close-up lenses as ''diopters'', after the unit of measurement of their optical power. Close-up lenses do not affect exposure, unlike extension tubes, which also can be used for macro photography with a non-macro lens. Optical power Close-up lenses are often specified by their optical power in diopters, the reciprocal of the focal length in meters. For a close-up lens, the diopter v ...

Double-Gauss Lens
The double Gauss lens is a compound lens used mostly in camera lenses that reduces optical aberrations over a large focal plane. Design The earliest double Gauss lens, patented by Alvan Graham Clark in 1888, consists of two symmetrically-arranged Gauss lenses. Each Gauss lens is a two-element achromatic lens with a positive meniscus lens on the object side and a negative meniscus lens on the image side. In Clark's symmetric arrangement, this makes four elements in four groups: two positive meniscus lenses on the outside with two negative meniscus lenses inside them. The symmetry of the system and the splitting of the optical power into many elements reduces the optical aberrations within the system. There are many variations of the design. Sometimes extra lens elements are added. The basic lens type is one of the most developed and used photographic lenses. The design forms the basis for many camera lenses in use today, especially the wide-aperture standard lenses used with 35 ...

Accessory Shoe
file:Canon 350D Hot Shoe.jpg, Canon EOS 350D Hot shoe file:Konica Minolta Dynax 7D hot shoe.jpg, Proprietary hot shoe used by Minolta and older Sony cameras (Konica Minolta Maxxum 7D) A hot shoe is a mounting point on the top of a camera to attach a flash (photography), flash unit and other compatible accessories. It takes the form of an angled metal bracket surrounding a metal contact point which completes an electrical connection between camera and accessory for standard, brand-independent flash synchronization. The hot shoe is a development of the standardised "accessory shoe" or "cold shoe", with no flash contacts, formerly fitted to cameras to hold accessories such as a rangefinder, or flash connected by a Prontor-Compur, cable. The dimensions of the hot shoe are defined by the International Organization for Standardization (ISO) in ISO 518:2006. Details such as trigger voltage are not standardised; electrical incompatibilities are still possible between brands. Design ...
