A bright f/2.8-4.8 aperture and 240g weather-sealed build distinguish this 16-50mm zoom, delivering a 24-76mm equivalent range with sharp optics from three ED and three aspherical elements. Internal zooming that maintains balance on gimbals and a quick linear motor autofocus add video capability uncommon at its budget positioning. This lens suits travel and landscape photographers who need a lightweight, all-weather companion capable of 1:3.33 close-ups and crisp detail edge-to-edge.
