A digital camera or digicam is a camera that captures photographs in digital memory. Most cameras produced today are digital, and while there are still dedicated digital cameras, many more cameras are now being incorporated into mobile devices, portable touchscreen computers, which can, among many other purposes, use their cameras to initiate live video-telephony and directly edit and upload imagery to others. However, high-end, high-definition dedicated cameras are still commonly used by professionals.
Digital zoom is a method of decreasing the apparent angle of view of a digital photographic or video image. Digital zoom is accomplished by cropping an image down to a centered area with the same aspect ratio as the original, and usually also interpolating the result back up to the pixel dimensions of the original. It is accomplished electronically, with no adjustment of the camera's optics, and no optical resolution is gained in the process.
A digital single-lens reflex camera is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor.

The Canon EOS 7D is a cropped sensor digital single-lens reflex camera made by Canon. It was announced on 1 September 2009 with a suggested retail price of US$1,699. Among its features are an 18.0 effective megapixel CMOS sensor, HD video recording, its 8.0 frames per second continuous shooting, new viewfinder which offers 1.0X magnification and 100% coverage, 19-point auto-focus system, movie mode, and built-in Speedlite transmitter.
The Pentax K-x is a 12.4 megapixel digital single-lens reflex camera, announced on September 16, 2009. Pentax K-x uses an Exmor, Sony-made sensor. 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 Fujifilm FinePix HS10 is an ultrazoom bridge camera from Fujifilm that was announced in February 2010. It is the first model of the Fujifilm FinePix HS series.
The Pentax K-r is a 12.4-megapixel digital single-lens reflex camera, announced on September 9, 2010, and replaced the K-x in Pentax' line-up, with which it shares many features. The K-r is available in three body colors in North America, with other colors available only in the Japanese market. The K-r introduces a new SAFOX IX autofocus system and has a 3-inch display. There is a known issue with front focus and the Pentax K-r. In low kelvin light the camera has severe front focus and this cannot be corrected with the AF fine tune. Pentax did not solve the problem; it is thought the AF module is responsible for the problem.
The Pentax Q series is a series of mirrorless interchangeable-lens cameras made by Pentax and introduced in 2011 with the initial model Pentax Q. As of September 2012, it was the world's smallest, lightest interchangeable lens digital camera. The first models used a 1/2.3" back-illuminated sensor CMOS image sensor. The Q7, introduced in June 2013, uses a larger 1/1.7" type sensor. The Q system is now discontinued.
The Nokia 808 PureView is a Symbian-powered smartphone first unveiled on 27 February 2012 at the Mobile World Congress. It is the first smartphone to feature Nokia's PureView Pro technology, a pixel oversampling technique that reduces an image taken at full resolution into a lower resolution picture, thus achieving higher definition and light sensitivity, and enables lossless zoom. It was one of the most advanced camera phones at the time of its release in May 2012.
Fujifilm FinePix HS are a series of bridge cameras that started in February 2010 with the HS10 model. The special feature of the HS cameras is the manual zoom that - otherwise common only with system cameras - allows a quick and precise change of the focal length but demands two-handed operation.
The Pentax K-30 is a 16.3-megapixel Pentax digital single-lens reflex camera, announced on 21 May 2012. At its introduction, it was in the middle of Pentax's DSLR range, above the now-discontinued entry-level K-r, and below the semi-pro K-5 and successor K-5 II.
