The picture on the top was taken with the Mamiya CS 14 mm fish-eye lens from the new outlook tower at the harbour of Friedrichshafen. I used the built-in red filter to increase contrast. The picture on the right shows this tower (taken with the CS 50 mm 1:1.7 lens).
The picture on the bottom was taken with my Contax 167MT and the Tokina SL 17 mm lens on the same roll of film (which I changed mid-roll). I wanted to compare the angle of view of the Tokina 17 mm lens to the Mamiya 14 mm fish-eye lens.
