Fujinon
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 many 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.

Fujifilm X-mount
The Fujifilm X-mount is a lens mount for Fujifilm interchangeable lens mirrorless cameras in its X-series, designed for 23.6mm x 15.6mm APS-C sensors. Various lens manufacturers use this mount, such as Fujifilm's own XF and XC lenses, Carl Zeiss AG ( Touit lenses), Samyang Optics, Handevision, SLR Magic, Viltrox and Zhongyi Optics. Additionally, a host of adapters for a range of SLR lenses are available, allowing the mounting of lenses (without autofocus or auto aperture) from Canon, Nikon, Pentax, Minolta, Contax/Yashica, Konica and more. This mount type should not be confused with the discontinued Fujica X-mount, which is not compatible with the newer X-mount without an adapter. Fujifilm X-Mount cameras The X-mount was fist announced in January 2012 with its use in the X-Pro1 body. Fujifilm has released the following cameras that use the X-mount: Sensor: , , , , , , Fujinon XF and XC lenses Fujifilm's "XF" and "XC" lense ...

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, ...

Fujica X Bayonet
The Fujica X-mount was a lens mount created by Fujifilm in the late 1970s and early 1980s for the new Fujica SLR lineup: AX-1, AX-3, AX-5, AX Multi, STX-1, STX-1N, STX-2, MPF105X, MPF105XN. It replaced the M42 screw mount used on their earlier SLRs. The mount is a bayonet type, with a 65° clockwise lock, and a flange focal distance of 43.5 mm.AX-1 owner's manual With the advent of autofocus, the Fujica series of 35 mm SLR cameras was discontinued in 1985, rendering this mount obsolete. Fuji would return to the SLR market in 2000 with a series of digital SLR cameras starting with the FinePix S1 Pro, but these were based on Nikon designs and used the autofocus version of the Nikon F-mount. Fujifilm introduced a line of twenty-seven X-Fujinon lenses with this mount (as well as three Fujinar lenses): Fujifilm X-Fujinon lenses The following lists Fujifilm X-Fujinon lenses with this mount (not including Fujinar lenses with this mount).

Soft Focus
In photography, soft focus is a lens flaw, in which the lens forms images that are blurred due to uncorrected spherical aberration. A soft focus lens deliberately introduces spherical aberration which blurs fine texture in the image while retaining sharp edges across areas of high contrast; 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 Effect Soft focus has been described as "an image that is in focus but has a halo of out-of-focus images around it." The first deliberate use of undercorrected spherical aberration, resulting in halos around highlights (also known as "pearly" highlights), is thought to have been by French pictorialists around 1900, spreading to the United States, where these lenses were most popular between 1910 and 1930. Noted practitioners of soft focus photography include Julia Margaret Cameron, Bob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zuiko
Zuiko ( or ) 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 () means 'Holy Light', using a character from the Mizuho Optic Research Laboratory (), where the lens was developed, and a character from Takachiho Corporation (), 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''. Optical formula nomenclature For lenses manufactured until approximately 1972, the number of optical elements of the lens, angle of view, and diaphragm operation could be distinguished by the markings engraved on the lens. The engraving dropped the number of elements with the advent of multicoating, which occurred during the production of OM system lenses. Ace, Pen-F, FTL, and early OM system lenses carry the letter prefix denoting the number of optical elements. Later OM system lenses (ge ...

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 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 '' Minolta AF Apo Tele ...

Nikkor
Nikkor is the brand of lenses produced by Nikon Corporation, including camera lenses for the Nikon F-mount and more recently, for the Nikon Z line of mirrorless cameras. Nikko parent company brand, from which the Nikkor brand evolved.

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). * Z ...
