Sigma Art AFG9C0 85mm
Featuring an f/1.2 maximum aperture and dual HLA-driven autofocus, this 85mm prime lens delivers razor-thin depth of field and fast, silent focusing for L-Mount portraits. Its 14-element optical design maintains sharpness wide open, with a 9-blade diaphragm rendering smooth bokeh. Portrait photographers seeking uncompromising subject isolation will find it ideal, though the 1130g weight limits travel use.
