Nikon Speedlight
Speedlight is the brand name used by Nikon Corporation for their photographic flash units, used since the company's introduction of strobe flashes in the 1960s. Nikon's standalone Speedlights (those not built into the company's cameras) have the ''SB-'' prefix as part of their model designation. Current Speedlights and other Nikon accessories make up part of Nikon's ''Creative Lighting System'' (CLS), which includes the ''Advanced Wireless Lighting'', that enables various Nikon cameras to control multiple Nikon flash units in up to three separate controlled groups by sending encoded pre-flash signals to slave units. Nikon's competitors like Canon and Ricoh use the similar name Speedlite for their flashes. Both names indicate that strobe flashes produce much shorter and more intense bursts of light than earlier photographic lighting systems, such as flashbulbs, or continuous lamps used in some studio situations. Models Nikon's Speedlight units are: (Update September 15, 2014) * SB ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brand Name
A brand is a name, term, design, symbol or any other feature that distinguishes one seller's good or service from those of other sellers. Brands are used in business, marketing, and advertising for recognition and, importantly, to create and store value as brand equity for the object identified, to the benefit of the brand's customers, its owners and shareholders. Brand names are sometimes distinguished from Generic brand, generic or store brands. The practice of branding - in the original literal sense of marking by burning - is thought to have begun with the ancient Egyptians, who are known to have engaged in livestock branding as early as 2,700 BCE. Branding was used to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron. If a person stole any of the cattle, anyone else who saw the symbol could deduce the actual owner. The term has been extended to mean a strategic personality for a produ ...

Hotshoe
Canon EOS 350D Hot shoe Proprietary hot shoe used by Minolta and older Sony cameras (Konica Minolta Maxxum 7D">Sony.html" ;"title="Minolta and older Sony">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", with no flash contacts, formerly fitted to cameras to hold accessories such as a rangefinder, or flash connected by a cable. The dimensions of the hot shoe are defined by the International Organization for Standardization in ISO 518:2006. Details such as trigger voltage are not standardised; electrical incompatibilities are still possible between brands. Design The h ...

Nikon D60
The Nikon D60 is a 10.2-megapixel Nikon F-mount digital single-lens reflex camera announced in January 2008. The D60 succeeds the entry-level Nikon D40x. It features the Nikon EXPEED image processor introduced in the higher-end Nikon D3 and D300. Like a number of other entry-level Nikon DSLRs, the D60 has no in-body autofocus motor, and fully automatic autofocus requires the use of a lens with an integrated autofocus-motor. With any other lenses the camera's electronic rangefinder can be used to manually adjust focus. New features Compared to the D40, new features of the Nikon D60 include: *Stop-motion movie creation *Nikon EI-137 processor (same as D3000, D80, D40x, D40) * Self-cleaning sensor unit *Air-flow Control System that reduces the amount of dust that reaches the sensor *LCD Screen Orientation Rotation *Active D-Lighting (one level) *Kit lens with optical image stabilization for same kit price as D40 before the Nikon D60 was released on February 24, 2008. *Manual fl ...

Nikon D50
The Nikon'' ''D50 is a 6.1-megapixel entry-level digital single-lens reflex camera, sold from June 2005 until November 2006 by Nikon. It was Nikon's first DSLR aimed at the consumer market, and sold for US$899. It uses the Nikon F mount. The D50 is similar to the slightly older D70 using the same CCD sensor, with a slower maximum shutter speed and slightly smaller size; however, it continued to offer the internal focus motor of prior autofocus film and digital SLRs. Future entry-level Nikon DSLRs (D40, D60, D3000, D5000) would eliminate the internal focus motor and require these motors to be in the lenses. Lack of a focus-motor in the camera eliminated the ability to autofocus with late film-era Nikkor AF and AF-D lenses, though these lenses work well on the D50. Features It has a 23.7 mm by 15.6 mm DX format image sensor with 6.1 million effective pixels. It also has a 2.0" (50 mm) polysilicon TFT LCD with 130,000 pixels. The camera uses a through-the-lens full-ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nikon D3
The Nikon D3 is a 12.0-megapixel professional-grade full frame (35 mm) digital single lens reflex camera (DSLR) announced by the Nikon Corporation on 23 August 2007 along with the Nikon D300 DX format camera. It was Nikon's first full-frame DSLR. The D3, along with the Nikon D3X, was a flagship model in Nikon's line of DSLRs, superseding the D2Hs and D2Xs. It was replaced by the D3S as Nikon's flagship DSLR. The D3, D3X, D3S, D4, D4s, D5, D6, D700, D800, D800Е and Df are the only Nikon FX format DSLRs manufactured in Japan. The D3S was replaced by the D4 in 2012. Technology The D3 features a full-frame 35 mm equivalent CMOS image sensor measuring 23.9 mm × 36.0 mm. This sensor is larger than the DX format sensors of all previous Nikon DSLRs, and Nikon has coined the term " FX format" to describe it. While the D3's sensor has larger pixels than some previous DX sensors, some previous DX sensors have larger pixels. The design of the D3's CMOS sensor ...

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 surpasse ...

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.

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 His ...

Through-the-lens
In photography, through-the-lens metering (TTL metering) refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter. In some cameras various TTL metering modes can be selected. This information can then be used to set the optimal film or image sensor exposure ( average luminance), it can also be used to control the amount of light emitted by a flash unit connected to the camera. Description Through-the-lens metering is most often associated with single-lens reflex (SLR) cameras. In most film and digital SLRs, the light sensor(s) for exposure metering are incorporated into the pentaprism or pentamirror, the mechanism by which a SLR allows the viewfinder to see directly through the lens. As the mirror is flipped up, no light can reach there during exposure, the necessary amount of exposure needs to be determined before the actual exposure. Consequ ...
