What reviewers say

Both reviews find good value, quick quiet autofocus and useful stabilisation, with visible shading and distortion. ePHOTOzine finds excellent central sharpness throughout the range but weaker wide-angle edges and substantial colour fringing. Photography Blog finds fringing well controlled and stronger wide-angle sharpness, while reporting softer wide-open results at 50–105 mm that improve stopped down.
