Yea, I know the ones you’re talking about…. The type that adapts to a normal lens.
The kind that goes on a point and shoot camera or video camera.

Not sure what your sigma is? But the 10.5 fisheye is one of the few fisheye lenses around which is full-frame on a non full frame camera (such as any Nikon DSLR)

My sigma is an 180deg fisheye lens at 15mm. So my question is why dose your lens have more depth and circular distort then mine? Because yours is 10.5mm?

Sample of mine....
