I can not agree with the previous speaker. The qualitative processing of the lens is good. Important to note, however, that you can not manually intervene in the auto focus and must -as must change in many other Objektiven- but only to switch on the lens to manual focusing; otherwise can damage the lens. The image services are good, the autofocus is due to the ultrasonic drive very quietly and accurately. The lens hood (hood) is very easy to attach without pressure filters must have a diameter of 52mm. With the focal lengths of 18-55mm lens covers wide angle from up in the short telephoto range. Who might want to change lenses and often reluctant to photograph at the telephoto end, which engages prefer to 18-70mm or 18-135mm lens. The value for money is good and the processing as mentioned nothing to fault: 5 points
