All of these photos were made with my AF DX Fisheye-Nikkor 10.5mm f/2.8G ED lens. Some were left with the fisheye effect in tact, some of my fisheye photos were corrected for the fisheye effect, which introduced a whole new kind of distortion as you can see in the rockfish photo, and some were corrected and cropped back down like in the Soyuz photo.
