For other uses, see camera (disambiguation). A camera is a device used to capture images, as still photographs or as sequences of moving images (movies or videos). The name is derived from camera obscura, Latin for "dark chamber", an early mechanism for projecting images, in which an entire room functioned much as a real-time imaging system. Cameras may work with the visual spectrum or other portions of the electromagnetic spectrum. 1 Description 2 History 3 Camera brands 4 External links A camera consists of some kind of enclosed hollow, with an opening or aperture at one end for light to enter, and a recording or viewing surface for capturing the light at the other end. Most cameras have a lens positioned in front of the camera's opening to gather the incoming light and to focus the image, or part of the image, on the recording surface. The diameter of the aperture is often controlled by a diaphragm mechanism, but some cameras have a fixed-size aperture. The size of the aperture and the brightness of the scene control the amount of light that enters the camera during a period of time, and the shutter controls the length of time that the light hits the recording surface. For example, in lower light situations, the shutter speed should be slower (longer time spent open) to allow the film to capture what little light is present. Due to the optical properties of camera lenses, only objects within a certain range of distances from the camera will be reproduced clearly. The process of adjusting this range is known as changing the camera's focus. There are various ways of focusing a camera accurately. The simplest cameras have fixed focus and ..." 2) "Telephoto" -- As to camera telephoto lens 1tele·pho·to Pronunciation: "te-l&-'fO-(")tO Function: adjective : being a camera lens system designed to give a large image of a distant object; also : relating to or being photography in which a telephoto lens is used Pronunciation Symbols

500 mm telephoto lens with extension tube.

In photography and cinematography, a telephoto lens is a specific construction of a long focal length photographic lens that places its optical centre outside of its physical construction, such that the entire lens assembly is between the optical centre and the focal plane. A regular lens of a focal length that is longer than what is considered a normal lens is not necessarily a telephoto lens. A telephoto lens has to incorporate a special lens group known as a telephoto group (see below); nevertheless, non-telephoto lenses of long focal length are often informally referred to as telephoto lenses. The angle of view created by a telephoto lens is the same as that created by an ordinary lens of the same specified focal length.

If a camera lens were to be constructed from a single lens of 200 mm focal length, then when the lens is focused on an object at infinity, the lens will be 200 mm away from the focal plane where the film or sensor is. The centre of the lens is referred to as the optical centre of the lens. Even constructing the lens out of multiple elements in the regular fashion, usually to eliminate aberrations, will still have the optical centre within the construction.

As the focal length of such lenses increases the physical length of lens becomes inconveniently long. But such lenses are not tele..."
