Delivering sharp images from an 11-element optical design with three aspherical elements, this 350g lens stands out for its all-metal build quality in a remarkably compact package. Its bright f/2 aperture and fast stepping motor autofocus provide strong performance for a premium feel at a mid-range price. This lens is best for portrait and street photographers using Sony E-mount who prioritize a lightweight, durable prime with a classic 50mm field of view.
