I will not go into great on the optical performance of the objective here has been written about enough, but the processing of the lens allows to wish in my eyes left. This is now the second objective that the Kuststoffbajonett jumped I have since the first time by tapping lightly on the Kamerarkörper. Okay, you can now say that was probably not appropriate use of the camera, still useable I would wish Nikon would process a metal bayonet here. Second, what was very auffählig both lenses is that the unlock after a certain time of use very hackelt (about one month normal use). Although he does and still does its job, but the effect of the hackeln entrigeln so close as in, you will feel no loss, the part does not work anymore in the next moment.
