With a 16mm 35mm-equivalent focal length and a generous ~106° angle of view, it excels in landscapes, architecture, astrophotography, and creative wide-angle effects. The lens features one extra-low dispersion (ED) element and two aspherical elements to reduce chromatic aberrations and distortion, and a Nano Coating System (NCS) to suppress flare and ghosting in difficult lighting. The aperture range of f/2.8-22 lets you work in low light or push for depth-of-field control, and it’s built with a solid all-metal mount and large 87mm front size. While the lack of autofocus means slower operation, full manual control offers precision for intentional shooting styles.
