Fast and direct
A photographer on the move needs to control things quickly and easily.
The zoom determines how big or large the subject is in the frame, image stabilization helps reduce shutter speeds and minimise any vibration whilst the large maximum aperture gives rich bokeh and high-speed AF keeps up with any movement.
This lens allows the photographer to control all the four elements with their left hand, leaving no room for uncertainty.
This workhorse of a lens brings out the maximum potential of the camera and the photographer.
