Superzoom

A superzoom or ultrazoom lens is a type of photographic zoom lens with unconventionally large focal length factors, typically ranging from wide angle to extreme long lens focal lengths in one lens.[1][2] 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× (e.g., 28-85 mm or 70-210 mm) of a standard zoom lens, with lenses being 10×, 12×, 18×, or above considered superzoom.[1]

This article is about lenses for single-lens reflex (SLR) cameras. For non-SLR digital cameras with large focal length zoom lenses, see Bridge camera.

The Leica lens of the compact digital camera Panasonic Lumix DMC-TZ18 from 2010 has a maximum focal length (shown) of 384 mm (calculated equivalent to 35 mm film), minimum is 24 mm.

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.[3][4] The long focal lengths normally have to be combined with image stabilization.[5]
