I have just purchased a new Canon 8-15 mm fish-eye lens that promises to be useful and great fun. At 8 mm it photographs everything in front (even my feet) e.g. 180 degrees, and produces a circular picture on a full frame camera (see picture below of Wanganui), like the Canon 1DX that I use. At 15 mm it produces a square picture, but still showing the fish-eye effect. We plan a trip to Japan soon and I look forward to using this lens for city and land scapes.
