The fast and compact FE 28mm f/2 Lens from Sony. It boasts a fast maximum aperture of f/2 for selective focus effects and for working in low-light conditions. In order to ensure high-quality imaging in a range of conditions, the lens incorporates three aspherical elements, including one Advanced Aspherical, and two extra-low dispersion elements, all of which help minimize aberrations. For fast, responsive focusing the 28mm uses a linear motor and internal focus design. Also, it has a dust- and moisture-resistant construction that will permit operation in less-than-ideal weather conditions. Covering a wide-angle perspective, this compact 28mm will pair nicely with Sony's full-frame E-mount cameras. It can also be used on APS-C format cameras where it will provide a 42mm equivalent focal length. Two extra-low dispersion glass elements are featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality. A linear autofocus motor and internal focus design provide quick and precise autofocus performance and enable accurate and silent focusing while recording videos. The rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
