Superzoom


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.
