The 10.5mm f/2.8 DX Nikkor Fisheye is a crop frame (DX) lens, equivalent
to the old 16mm fisheye on film (the only DX lens I have). It is still
f/2.8 and $200 less than the full frame model:

-the second shot (of the tree and fruit) shows something I want to
experiment with more; nature shots where you can get a closeup plus context.
