DX Format
The Nikon DX format is an alternative name used by Nikon corporation for APS-C image sensor format being approximately 24x16 mm. Its dimensions are about (29 mm vs 43 mm diagonal, approx.) those of the 35mm format. The format was created by Nikon for its digital SLR cameras, many of which are equipped with DX-sized sensors. DX format is very similar in size to sensors from Pentax, Sony and other camera manufacturers. All are referred to as APS-C, including the Canon cameras with a slightly smaller sensor. Nikon has produced 23 lenses for the DX format, from macro to telephoto lenses. 35mm format lenses can also be used with DX format cameras, with additional advantages: less vignetting, less distortion and often better border sharpness. Disadvantages of 35mm lenses include generally higher weight and incompatible features such as autofocus with some lower-end DX cameras. Nikon has also produced digital SLRs that feature the larger Nikon FX format sensor that i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nikon FX Format
A full-frame DSLR is a digital single-lens reflex camera (DSLR) with a 35 mm image sensor format (). Historically, 35 mm was one of the standard film formats, alongside larger ones, such as medium format and large format. The full-frame DSLR is in contrast to full-frame mirrorless interchangeable-lens cameras, and DSLR and mirrorless cameras with smaller sensors (for instance, those with a size equivalent to APS-C-size film), much smaller than a full 35 mm frame. Many digital cameras, both compact and SLR models, use a smaller-than-35 mm frame as it is easier and cheaper to manufacture imaging sensors at a smaller size. Historically, the earliest digital SLR models, such as the Nikon NASA F4 or Kodak DCS 100, also used a smaller sensor. Kodak states that 35 mm film (note: in " Academy format", 21.0 mm × 15.2 mm) has the equivalent of 6K horizontal resolution, according to a senior vice president of IMAX. This equates to 10K horizontal resolution in full ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nikon D2X
The Nikon D2X is a 12.4-megapixel professional digital single-lens reflex camera (DSLR) that Nikon Corporation announced on September 16, 2004. The D2X was the high-resolution flagship in Nikon's DSLR line until June 2006 when it was supplanted by the D2Xs and, in time, the Nikon D3 range, Nikon D4 range and Nikon D5 — the latter three using a FX full-format sensor. Technology The D2X uses a DX-format CMOS sensor supplied by Sony instead of either a charge-coupled device or the Nikon proprietary LBCAST sensor which had both dominated Nikon's digital SLR lineup until the D2X. The camera supports the sYCC color space. The CMOS sensor used in the D2X has the ability to resolve about nine times more than the human eye. At 90 line pairs/millimeter (90 lp/mm), the sensor can resolve extremely fine detail. This makes the camera perform exceptionally well when used as a landscape or scenic imager, since it can better resolve smaller detail in distant objects. The D2X surpa ...

Nikon D2H
The Nikon D2H is a professional-grade digital single-lens reflex camera introduced by Nikon Corporation on July 22, 2003. It uses Nikon's own JFET- LBCAST sensor with a 4.1-megapixel resolution, and is optimised for sports and action shooting that require a high frame rate. In 2005, the D2H was replaced by the D2Hs, which added new features derived from the 12-megapixel D2X digital SLR. The D2Hs was discontinued after the introduction of the D300 and D3 models. Like most early Nikon Digital SLR cameras, it uses a "DX Format" sensor, which applies a crop factor compared to 35 mm film of approximately 1.5×. D2Hs The D2Hs was announced on February 16, 2005, adding several improvements to the D2H design, although with the same sensor and body. Nikon added an improved light metering system, faster subject acquisition and tracking algorithms to the Multi-CAM-2000 Autofocus module, and expanded both the JPEG and RAW continuous shooting buffer. Nikon also reported improve ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nikon D1
The Nikon D1 is a digital single-lens reflex camera (DSLR) made by Nikon Corporation introduced on June 15, 1999. It featured a 2.7-megapixel image sensor, 4.5-frames-per-second continuous shooting, and accepted the full range of Nikon F-mount lenses. The camera body strongly resembled the F5 and had the same general layout of controls, allowing users of Nikon film SLR cameras to quickly become proficient in using the camera. Autofocus speed on the D1 series bodies is extremely fast, even with "screw-driven" AF lenses. Although Nikon and other manufacturers had produced digital SLR cameras for several years prior, the D1 was the first professional digital SLR that displaced Kodak's then-undisputed reign over the professional market. Unusual for a DSLR, the D1 uses the NTSC color space instead of the conventional sRGB or Adobe RGB color spaces. The resulting color on the D1 can be a bit unorthodox, but methods of correcting and/or compensating for the color problem are readil ...

Crop Factor
In digital photography, the crop factor, format factor, or focal length multiplier of an image sensor format is the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital cameras, relative to 35 mm film format as a reference. In the case of digital cameras, the imaging device would be a digital sensor. The most commonly used definition of crop factor is the ratio of a 35 mm frame's diagonal (43.3 mm) to the diagonal of the image sensor in question; that is, CF=diag35mm / diagsensor. Given the same 3:2 aspect ratio as 35mm's 36 mm × 24 mm area, this is equivalent to the ratio of heights or ratio of widths; the ratio of sensor areas is the square of the crop factor. The crop factor is sometimes used to compare the field of view and image quality of different cameras with the same lens. The crop factor is sometimes referred to as the focal length multiplier ("Film") since multiplying a l ...

Image Circle
The image circle is the cross section of the cone of light transmitted by a lens or series of lenses onto the image plane. When this light strikes a perpendicular target such as photographic film or a digital camera sensor, it forms a circle of light – the image circle. Various sensor aspect ratios may be used which all fit inside the same image circle, 3:2, 4:3, 16:9, etc. A lens to be used on a camera that provides movements must have an image circle larger than the size of the image format (Adams 1980, 54). To avoid vignetting, a photographer using a view camera must ensure that the area remains within the image circle (Adams 1980, 56–57; 151–52; 157–61); a tilt/shift lens or perspective-control lens used on a small- or medium-format camera usually has mechanical limitations that keep the frame area within the image circle. See also *Film format *Image sensor format In digital photography, the image sensor format is the shape and size of the image sensor. T ...

Normal Lens
In photography and cinematography, a normal lens is a lens that reproduces a field of view that appears "natural" to a human observer. In contrast, depth compression and expansion with shorter or longer focal lengths introduces noticeable, and sometimes disturbing, distortion. The problem Photographic technology employs different physical methods from the human eye in order to capture images. Thus, manufacturing optics which produce images that appear natural to human vision is problematic. The eye has a nominal focal length of approximately 17mm, but it varies with accommodation. The nature of human binocular vision, which uses two lenses instead of a single one, and post-processing by the cortex is very different from the process of making and rendering a photograph, video or film. The structure of the human eye has a concave retina, rather than a flat sensor. This produces effects observed by Abraham Bosse, who in his 1665 illustration 'To prove that one can neither define ...

Wide-angle Lens
In photography and cinematography, a wide-angle lens refers to a lens whose focal length is substantially smaller than the focal length of a normal lens for a given film plane. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior and landscape photography where the photographer may not be able to move farther from the scene to photograph it. Another use is where the photographer wishes to emphasise the difference in size or distance between objects in the foreground and the background; nearby objects appear very large and objects at a moderate distance appear small and far away. This exaggeration of relative size can be used to make foreground objects more prominent and striking, while capturing expansive backgrounds. A wide angle lens is also one that projects a substantially larger image circle than would be typical for a standard design lens of the same focal length. This large image circle enables either ...

Telephoto Lens
A telephoto lens, in photography and cinematography, is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a ''telephoto group'' that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as ''telephoto lenses'', although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group. Telephoto lenses are sometimes broken into the further sub-types of short telephoto (85–135 mm in 35 mm film format), medium telephoto: (135–300 mm in 35 mm film format) and super telephoto (over 300 mm in 35 mm film format) .
