Nikon F5
The Nikon F5 is a 135 film, 35 mm Photographic film, film-based single-lens reflex camera body manufactured by Nikon from 1996 through 2004. It was the fifth in Nikon's professional film camera line, which began in 1959 with the Nikon F. It followed the Nikon F4 of 1988, which had introduced in-body autofocus to Nikon's professional line. The F5 was in turn succeeded by the Nikon F6, as well as Nikon's parallel range of professional digital SLRs, beginning with the Nikon D1. Design Important advances in the F5 included: * Nikon 3-D color matrix meter (the F4 had introduced multi-segment matrix metering to the F series, but color sensing was new). * A self-diagnostic and self-adjusting shutter. * A mirror-balance system that reduced camera shake. * Electronically controlled exposure times from 1/8000 second to 30 seconds. * Built-in 8 frame per second motor drive (up from 5.7 frame/s on the F4). * 1/300 second flash sync (up from 1/250 on the F4). However, at 1/300 second, flash uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vibration Reduction
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation. It is mainly used in high-end image-stabilized binoculars, still and video cameras, astronomical telescopes, and also smartphones. With still cameras, camera shake is a particular problem at slow shutter speeds or with long focal length lenses (telephoto or zoom). With video cameras, camera shake causes visible frame-to-frame jitter in the recorded video. In astronomy, the problem of lens shake is added to variation in the atmosphere, which changes the apparent positions of objects over time. Application in still photography In photography, image stabilization can facilitate shutter speeds 2 to 5.5 stops slower (exposures 4 to ti ...

Film Speed
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras. Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a ''slow film''. Highly sensitive films are correspondingly termed ''fast films''. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor. Film speed measurement systems Hi ...

Bayer Filter
A Bayer filter mosaic is a color filter array (CFA) for arranging RGB color filters on a square grid of photosensors. Its particular arrangement of color filters is used in most single-chip digital image sensors used in digital cameras, camcorders, and scanners to create a color image. The filter pattern is half green, one quarter red and one quarter blue, hence is also called BGGR, RGBG, GRBG, or RGGB. It is named after its inventor, Bryce Bayer of Eastman Kodak. Bayer is also known for his recursively defined matrix used in ordered dithering. Alternatives to the Bayer filter include both various modifications of colors and arrangement and completely different technologies, such as color co-site sampling, the Foveon X3 sensor, the dichroic mirrors or a transparent diffractive-filter array. Explanation Bryce Bayer's patent (U.S. Patent No. 3,971,065) in 1976 called the green photosensors ''luminance-sensitive elements'' and the red and blue ones ''chrominance-sensi ...

Indium Tin Oxide
Indium tin oxide (ITO) is a ternary composition of indium, tin and oxygen in varying proportions. Depending on the oxygen content, it can be described as either a ceramic or an alloy. Indium tin oxide is typically encountered as an oxygen-saturated composition with a formulation of 74% In, 18% Sn, and 8% O by weight. Oxygen-saturated compositions are so typical that unsaturated compositions are termed ''oxygen-deficient ITO''. It is transparent and colorless in thin layers, while in bulk form it is yellowish to gray. In the infrared region of the spectrum it acts as a metal-like mirror. Indium tin oxide is one of the most widely used transparent conducting oxides because of its electrical conductivity and optical transparency, the ease with which it can be deposited as a thin film, and its chemical resistance to moisture. As with all transparent conducting films, a compromise must be made between conductivity and transparency, since increasing the thickness and increasing the concent ...

PC Card
In computing, PC Card is a configuration for computer parallel communication peripheral interface, designed for laptop computers. Originally introduced as PCMCIA, the PC Card standard as well as its successors like CardBus were defined and developed by the Personal Computer Memory Card International Association (PCMCIA). It was originally designed as a standard for memory- expansion cards for computer storage. The existence of a usable general standard for notebook peripherals led to many kinds of devices being made available based on their configurability, including network cards, modems, and hard disks. History The PCMCIA 1.0 card standard was published by the Personal Computer Memory Card International Association in November 1990 and was soon adopted by more than eighty vendors. It corresponds with the Japanese JEIDA memory card 4.0 standard. SanDisk (operating at the time as "SunDisk") launched its PCMCIA card in October 1992. The company was the first to introduce ...

Nikon F90
The Nikon F90 (known as the N90 in the United States) is a 35mm SLR camera manufactured between 1992 and 2001 and replaced the earlier Nikon F-801 (N8008 in the U.S.). At the time of its release it was noted for its fast autofocus speed compared to previous Nikon models, which had lagged behind competitor Canon's. It was thus seen by many as a 'stop-gap' measure to prevent the mass migration of many Nikon-using professional photographers to Canon, as Nikon's next fully professional camera, the F5, was some time away from release. The Nikon F4, the professional model available at the time of the F90's release, had very slow autofocus compared to Canon's autofocus SLRs. The Nikon F90's autofocus system was driven by a small 'peanut' motor in the camera body that drove the lens via a mechanical link, unlike Canon's autofocus system, which used motors built into each lens. It was also the first Nikon SLR to interoperate with the first generation of Nikkor lenses featuring internal fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
