As Canon’s first 85mm L-series lens with image stabilization, its f/1.4 aperture and optical design with an aspherical and ED element yield sharp portraits with smooth bokeh. Dust- and water-resistant construction combined with fluorine coatings ensures reliable performance in harsh outdoor conditions. Wedding and portrait photographers who frequently shoot handheld in dim venues will benefit most from the stabilized fast aperture and ring-type ultrasonic autofocus.
