Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens, photographic lens or photographic objective is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
Entry-level compact cameras typically use sensors known as 1/2.3″, which is 3% the size of a full-frame sensor. There are fixed-lens cameras — such as bridge cameras , premium compact cameras , or high-end point-and-shoot cameras — that offer sensors larger than 1/2.3″, but many still fall short of the larger sizes widely found in DSLRs.
A notable exception is the Nikon E2 and Nikon E3, using additional optics to convert the 35 mm format to a 2/3 CCD-sensor. A few 35 mm cameras have had digital camera backs made by their manufacturer, Leica being a notable example with the Leica R8–R9 .

Sputnik stereo camera. The two lower lenses are used for the photograph, while the third lens is used for composition. A stereo camera is a type of camera with two or more lenses with a separate image sensor or film frame for each lens.
Mamiya's C-Series, introduced in the 1960s, the C-3, C-2, C-33, C-22 and the Mamiya C330 and Mamiya C220 along with their predecessor the Mamiyaflex, [7] are the main conventional TLR cameras to feature truly interchangeable lenses. [8] "Bayonet-mount" TLRs, notably Rolleis & Yashicas, had both wide-angle and tele supplementary front add-ons ...
Visual sensor networks are most useful in applications involving area surveillance, tracking, and environmental monitoring.Of particular use in surveillance applications is the ability to perform a dense 3D reconstruction of a scene and storing data over a period of time, so that operators can view events as they unfold over any period of time (including the current moment) from any arbitrary ...
Thomas Edison developed a portable film camera in 1896. [2] Polish inventor Kazimierz Prószyński first demonstrated a hand-held film camera in 1898 but it was not reliable. [3] From 1909 to 1911, directors Francesco Bertolini and Adolfo Padavan, with assistant director Giuseppe de Liguoro, shot scenes for L'Inferno, based on Dante's The ...
