Weighing just 181g with an f/2.8 aperture and weather sealing, this ultra-wide prime pairs a bright optical design with a customizable control ring. Its 0.26x magnification and 130mm minimum focus distance add creative close-up versatility rare for a 16mm lens. This is best for street and travel photographers who need a rectilinear, full-frame wide-angle that won’t weigh down a small kit.
