Pentax K200D
The Pentax K200D is a 10.2-megapixel digital single-lens reflex camera, announced on January 24, 2008, along with the higher-end Pentax K20D, K20D. It was discontinued in December 2008, giving it the distinction of being one of the shortest-lived DSLR cameras. The K200D is the successor to the well-reviewed K100D, K110D, and K100D Super 6-megapixel DSLR's from Pentax, from which it retains body construction, penta-mirror viewfinder and autofocus module. The K200D adopts several of the features of the more advanced K10D, namely its 10.2 megapixel CCD sensor and body weather-sealing. The suggested retail price, MSRP of the Pentax K200D was $620 for the body only at launch, or $699 with an updated 18-55mm II f-number, 3.5-5.6 kit lens. Features The Pentax K200D has 60 seals for weather/dust resistance. It uses non-proprietary AA batteries like previous Pentax entry-level offerings. The K200D's lens mount is the K-mount; so it is compatible with Pentax (and third-party) lenses d ...

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 ...

K100D Super
The Pentax K100D and similar Pentax K110D are 6-megapixel digital single-lens reflex cameras, launched in the U.S. on May 22, 2006. The K100D has a maximum resolution of 3008 x 2008, and can also down-sample to 2400 x 1600 and 1536 x 1024. The slowest metered shutter speed is 30 seconds and the fastest shutter is 1/4000 seconds. The K100D features a 6-megapixel CCD sensor, coupled with an analog-to-digital converter (ADC) and a sensor-based shake reduction system within the camera body. The K110D has exactly the same features as the K100D, except it lacks built-in shake reduction. The K100D is sometimes confused with the similarly named, but more advanced, Pentax K10D. The Pentax K200D, successor to the K100D and K100D Super, was officially announced on January 23, 2008. K100D Super On June 27, 2007, Pentax announced the K100D Super.

Camera Labs
A camera is an optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera domain are film, videography, and cinematograph ...

M42 Lens Mount
The M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. It is more accurately known as the M42 × 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch. (The M42 lens mount should not be confused with the T-mount, which shares the 42mm throat diameter, but differs by having a 0.75mm thread pitch.) It was first used by the East German brands VEB Zeiss Ikon in the Contax S of 1949, and KW in the Praktica of the same year. VEB Zeiss Ikon and KW were merged into the Pentacon brand in 1959, along with several other East German camera makers. M42 thread mount cameras first became well known under the Praktica brand, and thus the M42 mount is known as the Praktica thread mount.The M42 mount is sometimes referred to as a "P" thread. See, e.g., Since there were no proprietary elements to the M42 mount, many other manufacturers used it; this ha ...

K-mount
The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras. Mounts The Pentax K-mount has undergone a number of evolutions over the years as new functionality has been added. In general, the term K-mount may refer to the original K-mount, or to all its variations. Originally designed by Zeiss for an alliance with Pentax, it was intended to be a common lens mount for a proposed series of cameras and lenses. However, the plan failed to work out and the two firms parted company amicably, but Pentax retained the lens mount and at least one Zeiss lens design for its own use. K-mount The original K-mount is a simple bayonet conn ...

Ruislip Lido MMB 01
Ruislip ( ) is an area in the London Borough of Hillingdon in West London, and in the historic county of Middlesex. Ruislip lies west-north-west of Charing Cross, London. The manor of Ruislip appears in the Domesday Book, and some of the earliest settlements still exist today, designated as local heritage sites. The parish church, St Martin's, dates back to the 13th century and remains in use. The buildings at the northern end of Ruislip High Street form the core of the original village square and are now Grade II listed. It originally featured a central water pump, but this was moved out of the road in the 1970s as a result of increased traffic. The expansion of the Metropolitan Railway from Harrow in the early 20th century acted as a catalyst for development in the area. Ruislip station opened in 1904, and a new urban district was created to reflect the forthcoming population growth; the Ruislip-Northwood Urban District split from the Uxbridge Rural District and continued ...

F-number
In optics, the f-number of an optical system such as a camera lens is the ratio of the system's focal length to the diameter of the entrance pupil ("clear aperture").Smith, Warren ''Modern Optical Engineering'', 4th Ed., 2007 McGraw-Hill Professional, p. 183. It is also known as the focal ratio, f-ratio, or f-stop, and is very important in photography. It is a dimensionless number that is a quantitative measure of lens speed; increasing the f-number is referred to as ''stopping down''. The f-number is commonly indicated using a lower-case hooked f with the format ''N'', where ''N'' is the f-number. The f-number is the reciprocal of the relative aperture (the aperture diameter divided by focal length). Notation The f-number is given by: N = \frac \ where f is the focal length, and D is the diameter of the entrance pupil (''effective aperture''). It is customary to write f-numbers preceded by "", which forms a mathematical expression of the entrance pupil diameter ...

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 ...
