A superzoom or ultrazoom lens is a type of photographic

zoom lens 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-focal-length (FFL) lens (see prime lens). A true zoom lens, also called a parfocal lens, is one t ...

to extreme long lens focal lengths in one lens. There is no clear definition of a superzoom lens, but the name generally covers lenses that have a range well above the 3× or 4× of a standard zoom lens, with lenses being 10×, 12×, 18×, or above considered superzoom. Due to trade-offs in the optical design, superzoom lenses are noted for having poorer optical quality at the extreme focal length ranges, mostly distortion at max wide angle and long lens ranges. The long focal lengths normally have to be combined with

image stabilization Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pit ...
