Focal length — The focal length of an optical system is a measure of how strongly it converges (focuses) or diverges (diffuses) light. A system with a shorter focal length has greater optical power than one with a long focal length. Thin lens approximation For… … Wikipedia
focal length — F/A/V abbreviated as FL, it is the distance, in millimeters, between the center of a lens and the point where the image comes into focus. The value given to a lens, stated in inches or millimeters. The shorter the focal length, the wider the… … Audio and video glossary
Lens speed — refers to the maximum aperture diameter, or minimum f number, of a photographic lens. A lens with a larger maximum aperture (that is, a smaller minimum f number) is a fast lens because it delivers more light intensity (illuminance) to the focal… … Wikipedia
Lens (optics) — For other uses, see Lens. A lens. Lenses can be used to focus light. A lens is an optical device with perfect or approximate axial symmetry which tra … Wikipedia
Lens (anatomy) — Crystalline lens (anatomy) Light from a single point of a distant object and light from a single point of a near object being brought to a focus by changing the curvature of the lens … Wikipedia
History of the single-lens reflex camera — The history of the single lens reflex camera predates the invention of photography in 1826/27 by one and a half centuries with the use of a reflex mirror in a camera obscura first described in 1676. Such SLR devices were popular as drawing aids… … Wikipedia
Photographic lens — A photographic lens (also known as objective lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media… … Wikipedia

Zoom lens — Nikkor 28 200 mm zoom lens, extended to 200 mm at left and collapsed to 28 mm focal length at right A zoom lens is a mechanical assembly of lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed… … Wikipedia
Normal lens — In photography and cinematography a normal lens is a lens that reproduces perspective that generally looks natural to a human observer under normal viewing conditions, as compared with lenses with longer or shorter focal lengths which produce an… … Wikipedia
Compound refractive lens — A Compound refractive lens (CRL) is a series of individual lenses arranged in a linear array in order to achieve focusing of X rays in the energy range of 5 40 keV. For all materials the refractive index for X rays is close to 1, hence a single… … Wikipedia
