High resolution: Edge-to-edge sharpness from the center to the corners of the frame is achieved by the precise arrangement of nine lens elements in six groups. This lens also contains two aspherical elements that serve to suppress the effects of deterioration of the image of the chromatic aberration and the imperfection of the curvature of the field.
Compact and lightweight: weighing only 130 g and a length of 46.5 mm, this new main lens is an excellent companion for all lenses in the X Series housing kit for the first purchase of a main lens.
Faster and quieter autofocus: The AF system with internal focusing uses a stepper motor to position the focusing elements using precise electrical impulses. In this way, the lens can focus quickly and accurately with almost silent operation.
