An excellent choice as a second lens to supplement a basic lens kit, this full-frame 28 mm wide-angle prime features a bright f/2 maximum aperture and outstanding overall optical performance. Advanced optics deliver excellent sharpness right out to the image edges, plus beautifully smooth bokeh when needed. A maximum aperture of f/2 makes it easier to shoot clear handheld images indoors or in dim lighting. An inner focus mechanism achieves stable, quiet autofocus operation ideal for movies as well as stills. For even wider perspectives, an optional 21 mm Ultra-wide Converter and 16 mm Fisheye Converter with full 180° (diagonal) coverage are available for extra expressive potential.
