The 85mm f/1.8 aperture and two ED elements deliver sharp subject separation with smooth bokeh and suppressed chromatic aberration for portraits. Its lightweight 454g body and suppressed focus breathing make it equally capable for handheld video work, while the dust- and splash-resistant design ensures reliability in harsh conditions. This lens is best for portrait photographers and hybrid shooters on the L-Mount system who need a weather-sealed, fast prime without the bulk.
