The lens incorporates an autofocus design that uses a high-torque DC coreless motor to shift all of the front lens elements (5 elements in 4 groups) to achieve a fast AF speed. The quick AF response is one of the fastest single focal length lenses on APS-sensor mirrorless cameras, according to a press release.
The high precision focus ring is made of metal, and requires delicate operation during manual focusing. The materials and the design ensure a comfortable feel and exactly the right amount of torque when rotating the ring.
According to Fujifilm, the new lens is a well-balanced, high-performance, single focal length lens, delivering great picture quality in a wide range of scenes including landscapes, snapshots and portraits.
