A superzoom or hyperzoom 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. 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. As of late 2019 the widest range superzoom lens is the Tamron 18-400mm F/3.5-6.3 Di II VC HLD with 22.2x zoom range.
