The Sony FE 85mm f/1.4 GM is a professional-grade full-frame E-mount prime lens designed for Sony a7-series cameras. Key features include:
Professional-grade portrait lens
Fast, nearly silent autofocus
Excellent low-light capabilities
Rounded eleven-blade aperture diaphragm
Full-Frame E-mount. As a part of the FE line of lenses, the FE 85mm f/1.4 GM is designed to cover the full-frame sensors on Sony a7-series cameras. Since it’s an E-mount lens, it’s also fully compatible with APS-C NEX cameras.
Pro-Grade Portrait Lens. The FE 85 GM’s fast f/1.4 aperture and short tele focal length make it perfect for portrait photography. At f/1.4, you’ll get dramatic shallow depth of field and excellent low-light capability.
Linear Super Sonic Wave Motor 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. There’s also a manual aperture ring that can be “de-clicked” for smooth aperture adjustment when shooting video.
G-Master Series Quality. The GM series is Sony’s premium lens offering. What sets it apart from other Sony lenses is an emphasis on an extremely high resolving power of fifty lines per mm, out-of-focus “bokeh” quality, and a robust, weather-sealed body.
Advanced Optics. The FE 85 GM uses one “XA” extreme aspherical element and three extra-low dispersion elements to minimize spherical and chromatic aberrations, and to produce clear, high-contrast images. The rounded eleven-blade aperture diaphragm produces smooth out-of-focus highlights when you desire a shallow depth of field.
