Its f/1.2 maximum aperture and 11-blade diaphragm produce exceptionally shallow depth of field with smooth, rounded bokeh, aided by Nano Crystal Coat and an ED element to suppress flare and aberrations. The lens pairs this optical performance with a robust, extensively weather-sealed build and a customizable control ring, despite its substantial 1160g weight. This is best for portrait and wedding photographers who demand uncompromising subject isolation and low-light capability in a professional Z-mount system.
