A digital camera, also called a digicam, is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film or film stock. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs.
A zoom lens is a system of camera lens elements for which the focal length can be varied, as opposed to a fixed-focal-length (FFL) lens.
Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a size ratio called optical magnification. When this number is less than one, it refers to a reduction in size, sometimes called de-magnification.
Macro photography is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life-size . By the original definition, a macro photograph is one in which the size of the subject on the negative or image sensor is life-size or greater. In some senses, however, it refers to a finished photograph of a subject that is greater than life-size.
The Leica Digilux 1 is a digital camera developed in partnership with Panasonic, which was released in 2002, roughly the same time as the Canon PowerShot G2 and the Nikon 2000. It is the second of Leica's digital offerings. Where the original Digilux was developed in partnership with Fuji Camera, the Digilux 1 was developed jointly with Panasonic; Leica is responsible for optics, while Panasonic designs the camera electronics. According to Leica, this allows both companies to design cameras that creates a harmonious matching of lens to sensor to produce color and contrast to Leica standards.
The Kodak EasyShare V570 was a 5-megapixel digital camera manufactured by Eastman Kodak. Announced on January 2, 2006, it was an upper-end model in the consumer price range, advertised at $400 in the United States in January 2006. It had an innovative dual lens system, combining two periscopic groups each with its own sensor: one very wide angle equivalent to a 23 mm in 135 format and a 3X zoom equivalent to a 39–117 mm, totalizing a virtual 5X zoom, with a step between 23 and 39 mm. It is the first dual lens digital camera. The model won a gold medal in the 2006 Industrial Design Excellence Awards.
