Full-Frame E-mount. As a part of the FE line of lenses, the FE 85mm f/1.8 is designed for Sony full-frame cameras like the a7 series. It’s also fully compatible with APS-C cameras, on which it’ll provide a 127mm equivalent focal length.
Pro-Grade Portrait Lens. The FE 85’s bright f/1.8 aperture and short tele focal length make it perfect for portrait photography. The f/1.8 maximum aperture gives you precise depth-of-field control and works well in low light.
Double Linear Autofocus System. This internal-focusing system provides fast, nearly silent, and highly accurate performance that’s great for still and video use. A dedicated focus hold button and AF/MF switch help to tailor focusing to your shooting needs.
Advanced Optics. The FE 85 f/1.8’s nine-element/eight-group design includes one extra-low dispersion element to minimize chromatic aberrations and color fringing, and to produce clear, high-contrast images. The rounded nine-blade aperture diaphragm gives you pleasing bokeh.
