I have first read all the reviews and you rausgelesen that there should be a good fisheye lens. At this price this is not surprising, but who will not expect much and use the lens just for fun, as I will be satisfied. The front ring wobbles comically because it is fixed at only one point (which I have already read); understand the meaning behind it, but does not bother me so much now. All in all, I find the lens for fun use sufficient and would choose again because of the price!
