K110D
The K110D is Pentax's entry-level DSLR. It has 6.1 Megapixels (6.1 Million effective pixels). The K110D is youngest of three sibling cameras in terms of specifications. It differs from the K100D only in lacking an in-body image stabilization system. The K110D has a 2.5 in LCD display screen with 210,000 pixels of resolution. It uses Secure Digital cards to record both JPEG and RAW image formats. The K110D uses AA alkaline batteries to power it, though an AC adapter is also compatible. It has a 23.5 mm x 15.7 mm CCD sensor to record its images. The body itself comprises a stainless steel chassis with a fiber reinforced plastic shell for durability. Continuous shooting mode allows for up to 2.8 frames per second to be recorded, which is five JPEGs (on highest quality setting) or three RAW format images. The Camera is compatible with PictBridge printers. The DSLR is considered "entry-class" among DSLRs. With firmware update, using SDHC cards is possible. Latest firmware ve ...

Pentax K100D
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. It retains the features and the 6.1-megapixel image sensor of the K100D, while adding support for Supersonic Drive Motor(SDM) lenses and du ...

Pentax KAF2 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JPEG
JPEG ( ) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet, and later social media. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG ...

Pentax K-m
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.

Shutter (photography)
In photography, a shutter is a device that allows light to pass for a determined period, exposing photographic film or a photosensitive digital sensor to light in order to capture a permanent image of a scene. A shutter can also be used to allow pulses of light to pass outwards, as seen in a movie projector or a signal lamp. A shutter of variable speed is used to control exposure time of the film. The shutter is constructed so that it automatically closes after a certain required time interval. The speed of the shutter is controlled by a ring outside the camera, on which various timings are marked. Camera shutter Camera shutters can be fitted in several positions: * Leaf shutters are usually fitted within a lens assembly (''central shutter''), or more rarely immediately behind (''behind-the-lens shutter'') or, even more rarely, in front of a lens, and shut off the beam of light where it is narrow. *Focal-plane shutters are mounted near the focal plane and move to uncover the fil ...

Aperture
In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An optical system typically has many openings or structures that limit the ray bundles (ray bundles are also known as ''pencils'' of light). These structures may be the edge of a lens or mirror, or a ring or other fixture that holds an optical element in place, or may be a special element such as a diaphragm placed in the optical path to limit the light admitted by the system. In general, these structures are called stops, and the aperture stop is the stop that primarily determines the ray cone angle and brightness at the image point. In some contexts, especially in photography and astronomy, ''aperture'' refers to the diameter of the aperture stop rather than the physical stop or the opening itself. For example, in a telescope, the aperture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exposure Value
In photography, exposure value (EV) is a number that represents a combination of a camera's shutter speed and f-number, such that all combinations that yield the same exposure have the same EV (for any fixed scene luminance). Exposure value is also used to indicate an interval on the photographic exposure scale, with a difference of 1 EV corresponding to a standard power-of-2 exposure step, commonly referred to as a stop. The EV concept was developed by the German shutter manufacturer in the 1950s ( Gebele 1958; Ray 2000, 318). Its intent was to simplify choosing among equivalent camera exposure settings by replacing combinations of shutter speed and ''f''-number (e.g., 1/125 s at ''f''/16) with a single number (e.g., 15). On some lenses with leaf shutters, the process was further simplified by allowing the shutter and aperture controls to be linked such that, when one was changed, the other was automatically adjusted to maintain the same exposure. This was especially he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PictBridge
PictBridge is a historical computing industry standard introduced in 2003 from the Camera & Imaging Products Association (CIPA) for direct printing. It allows images to be printed directly from digital cameras to a printer, without having to connect the camera to a computer. Its formal name is "Standard of Camera & Imaging Products Association CIPA DC-001 — 2003 Digital Solutions for Imaging Devices". CIPA DC-001-2003 Rev. 2.0 has been published in 2007. Implementation PictBridge is typically implemented using USB ports and the USB protocol. PictBridge-capable printers typically have a USB type A port which is connected by cable to the USB port of a PictBridge-capable digital camera (typically a Mini-B). The user selects the images on the camera to print. Licensing The PictBridge specification is not an open standard; it can only be obtained from CIPA after agreement not to disclose any information from the specification to others. In practice, this means that PictBridge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raw Image Format
A camera raw image file contains unprocessed or minimally processed data from the image sensor of either a digital camera, a motion picture film scanner, or other image scanner. Raw files are named so because they are not yet processed and therefore are not ready to be Photographic printing, printed, viewed or edited with a bitmap graphics editor. Normally, the image is processed by a raw converter in a wide-gamut internal color space where precise adjustments can be made before file format conversion, conversion to a viewable file format such as JPEG or PNG for storage, printing, or further manipulation. There are dozens of raw formats in use by different manufacturers of digital image capture equipment. Rationale Raw image files are sometimes incorrectly described as "digital Negative (photography), negatives", but neither are they negatives nor do the unprocessed files constitute visible images. Rather, the Raw datasets are more like Exposure (photography), exposed but Lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
