Pentax K2000
The Pentax K-m (called K2000 in U.S.) is a 10.2 megapixel digital single-lens reflex camera, announced on September 22, 2008 at the 2008 photokina trade show along with the DA-L series of lightweight, inexpensive lenses. It was discontinued in November 2009, being replaced by the more recent Pentax K-x. The K-m is considered a compact and entry-level model. It is significantly lighter than other Pentax DSLRs, lacks the weather sealing of the contemporaneous K200D and K20D models, and is intended to be sold with lightweight DA-L-series lenses. It does offer some improvements over the K200D, however, notably a maximum sensitivity increased from ISO 1600 to ISO 3200 and a slightly faster burst mode. The MSRP of the Pentax K2000 is $699 with DA-L 18-55mm 3.5-5.6 kit lens and AF200FG external flash unit.

Pentax
is a brand name used primarily by the Japanese multinational imaging and electronics company Ricoh for DSLR cameras, lenses, sport optics (including binoculars and rifle scopes), and CCTV optics. The Pentax brand is also used by Hoya Corporation for medical products & services, TI Asahi for surveying instruments, and Seiko Optical Products for certain optical lenses. Corporate history Early history The company was founded as Asahi Kogaku Goshi Kaisha in November 1919 by Kumao Kajiwara, at a shop in the Toshima suburb of Tokyo, and began producing spectacle lenses (which it still manufactures). In 1938 it changed its name to , and by this time it was also manufacturing camera/cine lenses. In the lead-up to World War II, Asahi Optical devoted much of its time to fulfilling military contracts for optical instruments. At the end of the war, Asahi Optical was disbanded by the occupying powers, being allowed to re-form in 1948. The company resumed its pre-war activities, manufacturi ...

Pentax K-x
The Pentax K-x is a 12.4 megapixel digital single-lens reflex camera, announced on September 16, 2009. The Pentax K-x uses a Sony Exmor sensor (different from the back-lit Exmor-R used in other Sony models). In some cases it even approaches the quality produced by full-frame DSLRs like the Nikon D700 and the Canon 5DMkII, both with larger sensors. The Pentax K-x is suitable for low light conditions for both still and video photography. The K-x is a compact model above the entry-level K2000/K-m. It is lighter than other Pentax DSLRs, including the K2000, and lacks the weather sealing of the K10D, K200D, K20D, and K-7, and is intended to be sold with lightweight DA-L-series lenses. It offers some improvements over the high-end K-7, including a maximum sensitivity of ISO12800 with lower noise than comparable cameras and even than some of higher class, a maximum shutter speed improved to 1/6000 s, and a faster burst mode of 4.7 frame/s.

Pentax K1000
The Pentax K1000 (originally marked the Asahi Pentax K1000) is an interchangeable lens, 35 mm film, single-lens reflex (SLR) camera, manufactured by Asahi Optical Co., Ltd. from 1976 to 1997, originally in Japan. The K1000's extraordinary longevity makes it a historically significant camera. The K1000's inexpensive simplicity was a great virtue and earned it an unrivaled popularity as a basic but sturdy workhorse. The Pentax K1000 eventually sold over three million units. Description The K1000, introduced in 1976, is the simplest member of Asahi Optical's Pentax K-series 35mm SLRs. The other members are the Pentax K2, KM, and KX, introduced in 1975, and the K2 DMD of 1976. All have the same basic body design, but with differing feature levels, electronics, and controls. The K1000 was the KM with the self-timer, depth of field pre-view and some other features removed to save cost.

Flash (photography)
A flash is a device used in photography that produces a brief burst of light (typically lasting 1/1000 to 1/200 of a second) at a color temperature of about 5500 K to help illuminate a scene. A major purpose of a flash is to illuminate a dark scene. Other uses are capturing quickly moving objects or changing the quality of light. ''Flash'' refers either to the flash of light itself or to the electronic flash unit discharging the light. Most current flash units are electronic, having evolved from single-use flashbulbs and flammable powders. Modern cameras often activate flash units automatically. Flash units are commonly built directly into a camera. Some cameras allow separate flash units to be mounted via a standardized accessory mount bracket (a ''hot shoe''). In professional studio equipment, flashes may be large, standalone units, or studio strobes, powered by special battery packs or connected to mains power. They are either synchronized with the camera using a flas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Suggested Retail Price
The list price, also known as the manufacturer's suggested retail price (MSRP), or the recommended retail price (RRP), or the suggested retail price (SRP) of a product is the price at which its manufacturer notionally recommends that a retailer sell the product. Suggested pricing methods may conflict with competition theory, as they allow prices to be set higher than would be established by supply and demand. Resale price maintenance—fixing prices—goes further than suggesting prices, and is illegal in many countries. Retailers may charge less than the suggested retail price, depending upon the actual wholesale cost of each item, usually purchased in bulk from the manufacturer, or in smaller quantities through a distributor. The suggested price is sometimes unrealistically high, so the seller can appear to be offering a discount. List price often cannot be compared directly internationally as products may differ in detail, sometimes due to different regulations, and list pr ...

Burst Mode (photography)
Burst mode, also called continuous shooting mode, sports mode, continuous mode, or burst shot, is a shooting mode in still cameras where several photos are captured in quick succession by either pressing the shutter button or holding it down. This is used mainly when the subject is in successive motion, such as sports photography. The photographer can then select the best image of the group or arrange them in a sequence to study the transitions in detail. Details The speed at which successive photographs can be captured depends on several factors, but mainly on the processing power of the camera. Disabling certain features such as post processing which the camera applies automatically after capturing each image will usually allow a faster rate of capture. While some cheaper point and shoot cameras may have a multi-image burst function which allows them to capture a number of frames within a second with a single shutter button press, most film and digital SLR cameras will cont ...

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 ...

Pentax K20D
The Pentax K20D and its clone, the Samsung GX-20, are 14.6 megapixel digital single-lens reflex cameras manufactured by Pentax that were announced on January 23, 2008. The K20D was available in the U.S. market from February 2008 through autumn 2009. The K20D and GX-20 bodies were developed by Pentax, while the CMOS sensor was manufactured by Samsung - a result of a partnership begun in 2005. Although both cameras share similar hardware, each camera has its own design, firmware, and image processing algorithms. The K20D is the first Pentax DSLR with a CMOS image sensor co-developed by Pentax and Samsung. Samsung's expertise in sensor design is seen as a major benefit to Pentax, which did not release its first DSLR until 2003, when most other camera manufacturers had already established themselves in the growing digital SLR market. At the time of their release, the K20D and GX-20 had the highest resolution sensor in the APS-C image sensor format at 14.6 megapixels. In 2009, Pentax ...
