Not a bad lens, but definitely a special lens. Focus and zoom are a bit stiff. On my D7200 it's a round fisheye from 6mm to about 8mm and from 9-11 it's rectangular. The lens hood is pretty much useless at the bottom - it gets in the way. You also have to be careful with the framing of the frame - if you're not in the frame your legs will be in the photo - but almost all fisheyes are like that.
