The 170-gram all-metal body is fully weather-sealed and pairs an f/2 maximum aperture with 0.08-second autofocus for quiet, precise focusing. Its 9-blade diaphragm and Nano-GI coated optics with two aspherical and two ED elements yield sharp, distortion-free images with pleasing background blur. Best suited for street and travel photographers who demand a compact, durable lens for candid environmental portraits and everyday shooting.
