I write very rarely reviews, but since I came here but a lot of good about this lens ("lens" is definitely the wrong word)'ve read, I see myself after its own assessment but forced himself to write a. My title sums it up already, the part is not really suitable for serious photos. Of course it was clear to me that I get for this price no professional device but that I do so not even manage the center has to present sharp but surprised me. From the edges I will not say anything, because no details were visible. I have tested it with a rather ordinary Nikon D5300 and I'm not too stupid to take pictures. I have many years quite good fisheye photographs with the original Nikon FC-E9 made essay on my old Coolpix 8800 and had here at least a comparable result expected. So that part is back and I'd rather save on a real fisheye lens from Nikon. Of course, this will cost even used almost tenfold, but what use a cheap part in which I am annoyed about each image.
