With a bright f/1.8 maximum aperture and a 9-blade diaphragm, this 85mm prime delivers smooth bokeh and sharp subject isolation in a compact 355g build. The lens's fast, quiet autofocus and suppressed focus breathing make it equally capable for video work, while dust and splash-resistant sealing ensures reliability outdoors. It’s best suited for portrait photographers who need a lightweight, weather-resistant lens for natural-light shooting on L-mount full-frame cameras.
