I'm having trouble understanding what designates a lens as a fisheye lens if the focal length is the same as (or can be the same as) a wide-angle lens.
For example - the NIKKOR 10.5mm f/2.8G ED AF DX is a Fisheye, the same with the 16mm f/2.8D. Why not just get the 10-24mm f/3.5-4.5G ED wide-angle that would cover both focal lengths and more? Is it because of the higher aperture of the fisheyes?
