The action of varying the focal length of a zoom lens to enlarge (zoom in) or reduce (zoom out) the image.
Also called a Variable focus lens. A lens in which focal length is variable - that is, focal lengths can be adjusted from wide angle to telephoto. Elements inside a zoom lens shift their positions, enabling the lens to change itsfocal length - in effect, providing one lens that has many focal lengths within a given range - e.g. 70mm to 200mm (as illustrated by the lens shown above).
Also known as a ZLR camera. A prosumer camera that has advanced features that are similar to an SLR (Single Lens Reflex) camera, but has a permanently fixed zoom lens instead of the ability to interchange lenses.
A lens on which the focal length can be varied, as opposed to a fixed focal length lens. Zooms come in various focal length ranges, such as 35 to 105mm all focal lengths including and within this range can be utilized.
Same as a Zoom Lens Reflex camera
A shot taken from a stationary position using a special zoom lens that magnifies or de-magnifies the center of the image. This creates an illusion that the camera is moving toward or away from its subject by making the subject more or less prominent in the frame. Not to be confused with dollying in which the camera itself actually physically moves closer to or further away from its subject.
A shot using a lens whose focal length is adjusted during the shot. Zooms are sometimes used in place of tracking shots, but the differences between the two are significant. A zoom normally ends in a close-up, a zoom-back in a general shot. Both types of shot imply a rapid movement in time and space, and as such create the illusion of displacement in time and space. A zoom-in picks out and isolates a person or object, a zoom-out places that person or object in a wider context. A zoom shot can be seen, therefore, as voyeurism at its most desirably perfect.

Short for Zoom Lens. Also, to manipulate a multi-focal length lens (aka zoom) through some or all of its focal length range, i.e. zoom in (go to tighter angle of view) or zoom out (go to wider angle of view).
Used instead of collections of fixed-focal-length lenses and, unfortunately, instead of a dolly.
A flash unit with a mechanism that adjusts the angle of coverage according to the focal length of the lens in use.
Electronic flash with adjustable angle of flash output, to cover angle of view of various lenses, e.g. Speedlite 430EX II zooms to cover lenses with focal lengths 24 to 105mm (full-frame format).
A zoom shot that ends in a freeze frame.
A variable focal length lens. The most common on digicams has a 3:1 ratio (i.e. 35-105mm). Detachable zoom lenses include for example, 24-70mm, 70-200mm and 100-400mm
A lens in which you adjust the focal length over a wide rangeof focal lengths. Subsituting lenses of many focal lengths. Zoom lenses whose focallength is continuously variable over a certain range without a change in focus; itsfocal length is changed by operating a separate zoom or a combination focusing/zoomring; difficult type of lens to design and manufacture, very useful for the photographeron a budget or one who likes to travel light.
A variable focal length lens. A zoom lens will have a third ring, besides ones controlling focus and iris, that will allow you to change the focal length within a range of wide to long.
A variable focal length lens. The most common zoom lens on digital cameras has a 3:1 ratio
Individual lens with variable focal lengths, achieved by movement of lens elements to change magnification. See Zoom. With projectors, allows adjusting size of image on screen by adjusting lens instead of moving projector. Zoom lens not as light efficient as fixed lens.
Variable focal length lens that allows the photographer enlarge or reduce the image
