Fujinon XF 56mm F1
Fujinon is a brand of optical lenses made by Fuji Photo Film Co., Ltd, now known as Fujifilm. Fujifilm's Fujinon lenses have been used by professional photographers and broadcast stations as well as cinematography. Fujifilm started manufacture of optical glass in its Odawara Factory in Japan in 1940, which was the start of the Fujinon brand. They were proud of their use of expensive Platinum crucibles to get the purest glass achievable at the time. Fujifilm also pioneered Electron Beam Coating (EBC) which according to Fujifilm, represented a new high in lens precision and performance. The EBC process was significantly different from other coating processes by the number of coating, the thinness of the coating, and the materials used for coating. Fujifilm claimed they were able to have as much as 14 layers of coating and used materials such as zirconium oxide, and cerium fluoride, which could not be used for coating in the conventional coating process.

Optical Lens
A lens is a transmissive optical device which focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a #Compound lenses, compound lens consists of several simple lenses (''elements''), usually arranged along a common Optical axis, axis. Lenses are made from materials such as glass or plastic, and are Grinding (abrasive cutting), ground and Polishing, polished or Molding (process), molded to a desired shape. A lens can focus light to form an image, unlike a Prism (optics), prism, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called lenses, such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses. Lenses are used in various imaging devices like telescopes, binoculars and cameras. They are also used as visual aids in glasses to correct defects of vision such as Near-sightedness, myopia and Far-sig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuji GX680
The Fuji GX680 is a series of single lens reflex system cameras for medium format film produced by Fujifilm with interchangeable camera lenses and interchangeable film holders for the unusual film format 6×8 cm on 120 and 220 roll film. The distinguishing feature of the Fuji GX680 is the articulating front standard, which runs on a rail connecting lens and camera body by a bellows; the interchangeable lens is permanently mounted to a lens board. In contrast to competing medium-format cameras, e.g. Mamiya RB67 and RZ67 and Rolleiflex SL66, for some models of the Fuji GX680 the front standard can be shifted right, left, up and down for perspective control, and the front standard can also be tilted on horizontal and vertical axes to control depth of field using the Scheimpflug principle. Therefore, the Fuji GX680 has many of the same camera movements of a large format view camera, only limited by restricted motions of the front standard and a fixed rear standard, making the ...

Photographic Lenses By Brand
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purp ...

Zuiko
Zuiko ( ja, ズイコー, italic=default or ja, 瑞光, italic=default, label=none) is a brand of optical lenses made by Olympus Corporation that was used up to and into the Four Thirds system era. The name Zuiko ( ja, 瑞光, italic=default, label=none) means 'Light of the Gods', using a character from the Mizuho Optic Research Laboratory ( ja, 瑞穂光学研究所, italic=default, label=none), where the lens was developed, and a character from Takachiho Corporation ( ja, 高千穂製作所, italic=default, label=none), which would eventually become the Olympus Corporation. With the introduction of the Micro Four Thirds system in 2008, new lenses for that system started to be branded as ''M.Zuiko Digital''.

Takumar
Takumar is the name that Asahi Optical gave to its lenses, notably but not exclusively those for its own SLR cameras. Named after the Japanese-American portrait painter, , whose brother Kumao Kajiwara founded Asahi Optical. The name adorned its lenses until 1975, when Asahi switched from the M42 screw mount to the bayonet K-mount. K-mount lenses were simply named "SMC Pentax". Some Takumar lenses were also made for the K-mount. Details The Takumar designation was used on lenses designed for Asahi's 35 mm cameras, 6×7 cameras, and for other purposes too. * ''Takumar'' lenses were made in M37 screwmount for the original Asahiflex cameras and continued into the M42 period. * ''Auto-Takumar'' lenses were a type of preset lens. The user selected an aperture then engaged a lever to energise the stopping-down mechanism. The camera would then trip this mechanism when the shutter was fired. * ''Super-Takumar'' lenses featured an improved form of lens coating (to reduce fl ...

Rokkor
Rokkor was a brand name used for all Chiyoda Kōgaku Seikō and later Minolta lenses between 1940 and 1980, including a few, which were marketed and sold by other companies like Leica. The name was derived from the name of Rokkō (六甲山), a 932 metre (3058') high mountain, which could be seen from the company's glass-making and optics factory at Mukogawa near Osaka, Japan. The company's founder wanted the name to symbolize the high quality in optics. Overview The first lens to carry the Rokkor designation was a 200mm 4.5 lens that came with the hand-holdable aerial camera Chiyoda SK-100 in 1940. After the Rokkor name was dropped and no longer engraved in new lenses after 1980/1981, the Rokkor name resurfaced two times. As was revealed not before 2006, the Rokkor name was still used internally for prototypes of a never released SR-mount '' Minolta MD Apo Tele Rokkor 300mm 2.8'' manual-focus lens in the early 1980s, a lens design, which later saw life as the A-mount ...

Nikkor
Nikkor is the brand of lenses produced by Nikon Corporation, including camera lenses for the Nikon F-mount. Nikko parent company brand, from which the Nikkor brand evolved. The ''Nikkor'' brand was introduced in 1932, a Westernised rendering of an earlier version ''Nikkō'' (日光), an abbreviation of the company's original full name ''Nippon Kōgaku'' ("Japan Optics"; 日本光学工業株式会社).The 75th Anniversary of NIKKOR Lenses'' (''Nikkō'' also means "sunlight" and is the name of a Japanese town.) In 1933, Nikon marketed its first camera lens under the Nikkor brand name, the "Aero-NIKKOR," for aerial photography. Nikon originally reserved the Nikkor designation for its highest-quality imaging optics, but in recent history almost all Nikon lenses are so branded. Notable Nikkor branded optics have included: * F-mount lenses for 35mm SLR and DSLR photography. For a full list see Nikon F-mount. * 1 mount lenses for Nikon CX format currently used by Nikon 1 series. * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tessar
The Tessar is a photographic lens design conceived by the German physicist Paul Rudolph in 1902 while he worked at the Zeiss optical company and patented by Zeiss in Germany; the lens type is usually known as the Zeiss Tessar. A Tessar comprises four elements in three groups, one positive crown glass element at the front, one negative flint glass element at the center and a negative plano-concave flint glass element cemented with a positive convex crown glass element at the rear. History Beginnings Despite common belief, the Tessar was not developed from the 1893 Cooke triplet design by replacing the rear element with a cemented achromatic doublet. Paul Rudolph designed the Anastigmat with two lenses cemented in 1890. Later, Rudolph thought that a narrow airgap in the form of a positive lens would correct the spherical aberration (as did HL Aldis in 1895) and that this device was much better than the lenses cemented. In addition, this allowed the photographers to hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soft Focus
In photography, soft focus is a lens flaw, in which the lens forms images that are blurred due to spherical aberration. A soft focus lens deliberately introduces spherical aberration in order to give the appearance of blurring the image while retaining sharp edges; it is not the same as an out-of-focus image, and the effect cannot be achieved simply by defocusing a sharp lens. Soft focus is also the name of the style of photograph produced by such a lens. Photography Because soft focus results from what are considered technical flaws, typically spherical and chromatic aberration, many older lenses had soft focus built in as a side effect of their construction. Some lens makers, such as Pinkham-Smith and Busch Nicola Perscheid (see Nicola Perscheid), intentionally designed lenses to take advantage of these flaws and, as color became available, chromatic aberration was less desirable, but well-managed spherical aberration was desirable. Newer lenses are optimized to minimize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
