A versatile wide-angle lens to suit working in a variety of situations, the Ultron 28mm f/2 from Voigtlander pairs a wide field of view with a bright f/2 maximum aperture. Its optical design employs high refractive index glass to control distortion and spherical aberrations in order to realize a high degree of sharpness and clarity, and a 10-blade diaphragm is also featured to contribute to a pleasing bokeh quality. Additionally, a manual focus design is also used, which permits working with subjects as close as 2.3' away, and a dedicated lens hood is included to shield the front element and reduce lens flare.
