Achieve soft, natural bokeh with a bright f/2 maximum aperture and 9 aperture blades.
The AF drive utilizes a newly developed, small-diameter, high-torque STM (stepping motor), enabling fast focus drive for high-speed, high-precision AF control.
The lens design considers video shooting, suppressing the angle of view fluctuation (focus breathing) that occurs during focusing, allowing for footage without unnatural angle changes.
The control ring can be assigned one of [M/A], [Aperture Value], [Exposure Compensation], or [ISO Sensitivity] from the camera. Its smooth operation allows for smooth and quiet shooting operations for both video and still images.
Features a dust and moisture resistant design with sealing to prevent the ingress of dust and water droplets, allowing you to shoot with peace of mind regardless of the weather.
