AC adapter

An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) is a type of external power supply, often enclosed in a case similar to an AC plug.

See Pentax K-7 and AC adapter

Active-pixel sensor

An active-pixel sensor (APS) is an image sensor, which was invented by Peter J.W. Noble in 1968, where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors.

See Pentax K-7 and Active-pixel sensor

APS-C

Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 30.15 mm field diameter.

See Pentax K-7 and APS-C

Autofocus

An autofocus (AF) optical system uses a sensor, a control system and a motor to focus on an automatically- or manually-selected point or area.

See Pentax K-7 and Autofocus

CMOS

Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss") is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.

See Pentax K-7 and CMOS

Digital Photography Review

Digital Photography Review, also known as DPReview, is a website about digital cameras and digital photography, established in November 1998.

Digital single-lens reflex camera

A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor.

See Pentax K-7 and Digital single-lens reflex camera

Facial recognition system

A facial recognition system is a technology potentially capable of matching a human face from a digital image or a video frame against a database of faces.

See Pentax K-7 and Facial recognition system

Flash synchronization

In photography, flash synchronization or flash sync is the synchronizing the firing of a photographic flash with the opening of the shutter admitting light to photographic film or electronic image sensor.

See Pentax K-7 and Flash synchronization

Gram

The gram (originally gramme; SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one thousandth of a kilogram.

See Pentax K-7 and Gram

High dynamic range

High dynamic range (HDR), also known as wide dynamic range, extended dynamic range, or expanded dynamic range, is a signal with a higher dynamic range than usual.

See Pentax K-7 and High dynamic range

High-definition video

High-definition video (HD video) is video of higher resolution and quality than standard-definition.

See Pentax K-7 and High-definition video

Hoya Corporation

is a Japanese company manufacturing optical products such as photomasks, photomask blanks and hard disk drive platters, contact lenses and eyeglass lenses for the health-care market, medical photonics, lasers, photographic filters, medical flexible endoscopy equipment, and software.

Light meter

A light meter (or illuminometer) is a device used to measure the amount of light.

See Pentax K-7 and Light meter

Lithium-ion battery

A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li+ ions into electronically conducting solids to store energy.

See Pentax K-7 and Lithium-ion battery

Live preview

Live preview is a feature that allows a digital camera's display screen to be used as a viewfinder. Pentax K-7 and Live preview are Live-preview digital cameras.

See Pentax K-7 and Live preview

Pentaprism

A pentaprism is a five-sided reflecting prism used to deviate a beam of light by a constant 90°, even if the entry beam is not at 90° to the prism.

See Pentax K-7 and Pentaprism

Pentax

was a Japanese camera and optical equipment manufacturer, and currently, it exists as the Pentax Life Care Business Division of Hoya's medical endoscope business, as well as the digital camera brand of Ricoh Imaging, a subsidiary of Ricoh.

Pentax K-5

The Pentax K-5 is a 16.3-megapixel digital single-lens reflex camera, announced on September 20, 2010. Pentax K-7 and Pentax K-5 are Live-preview digital cameras, pentax DSLR cameras and pentax K-mount cameras.

See Pentax K-7 and Pentax K-5

Pentax 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.

See Pentax K-7 and Pentax K-mount

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. Pentax K-7 and Pentax K20D are Live-preview digital cameras, pentax DSLR cameras and pentax K-mount cameras.

See Pentax K-7 and Pentax K20D

Pixel

In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest addressable element in a dot matrix display device.

See Pentax K-7 and Pixel

Prontor-Compur

A Prontor-Compur connection (also known as a PC connector, PC terminal, or PC socket) is a standard 3.5 mm (1/8") electrical connector (as defined in ISO 519, (1992-11-25). Photography -- Hand-held cameras -- Flash-connector dimensions. Geneva: International Organization for Standardization.) used in photography to synchronize the shutter to the flash.

See Pentax K-7 and Prontor-Compur

SD card

Secure Digital, officially abbreviated as SD, is a proprietary, non-volatile, flash memory card format the SD Association (SDA) developed for use in portable devices.

See Pentax K-7 and SD card

Through-the-lens metering

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.

See Pentax K-7 and Through-the-lens metering

Video Graphics Array

Video Graphics Array (VGA) is a video display controller and accompanying de facto graphics standard, first introduced with the IBM PS/2 line of computers in 1987, which became ubiquitous in the IBM PC compatible industry within three years.

See Pentax K-7 and Video Graphics Array

Viewfinder

In photography, a viewfinder is a small window the photographer looks through to see what a photo will look like before they capture it.
