a zoom lens with a large focal length range, for example an 18-200mm or 28-300mm; also, a point & shoot camera with such a lens built in.
Superzoom lenses have an extreme range of focal lengths, typically from wide angle to telephoto. These lenses are useful for travel or as "walkaround" lenses, as a single lens can cover most focal lengths and eliminate the need for carrying multiple lenses.
