An ideal portrait-length prime, the FE 85mm f/1.8 from Sony is a sleek short-telephoto lens designed for full-frame E-mount mirrorless cameras. The bright f/1.8 design is an ideal balance between speed and a compact form factor and the slightly long focal length offers a flattering perspective for portraiture and event photography. Optical Design Bright f/1.8 maximum aperture allows for fine-tuned control over depth of field and also benefits working in difficult lighting conditions. One extra-low dispersion element is featured in the optical design and helps to limit color fringing and chromatic aberrations for heightened image clarity and color accuracy. Rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques. Autofocus and Handling Double linear autofocus motor delivers smooth, precise, and near silent focusing performance to benefit both stills and video applications. Focus hold button on the lens barrel can be used to hold the focusing position, or can be set in-camera to control a variety of additional lens functions. AF/MF switch for tactile control over the focus mode. Dust- and moisture-resistant design for increased protection to the elements.
