This is a lens which can truly be described as a professional workhorse, with robust build (including dust and moisture resistance), wide F2.8 maximum aperture, fast and silent ultrasonic autofocus motor, and optical image stabilization for hand-holding at slow shutter speeds, moving vehicles and a lot more. 4 UD elements to provide compensation for chromatic aberration.
