The Sony FE 85mm f/1.8 is a full-frame E-mount portrait prime lens for Sony Alpha mirrorless cameras. Its fast f/1.8 aperture and short-telephoto focal length isolate subjects and blur the background smoothly. This suits interviews, headshots, corporate video, broadcast studio work and event capture.
The optical design has nine elements in eight groups, including one extra-low dispersion (ED) element that controls chromatic aberration. A nine-blade rounded diaphragm renders smooth, circular bokeh. A double linear autofocus motor drives fast, quiet focusing for stills and video. The lens has an on-barrel focus-hold button and an AF/MF switch.
The body is dust- and moisture-resistant and weighs 371 g. The lens covers the full-frame image circle. On APS-C E-mount bodies, the effective field of view is near 127 mm. It takes 67 mm front filters.
