Just remember though that the maximum available HAOV from a corrected fisheye image can be no wider than the HAOV of the fisheye view (which has a linear relationship to the diagonal). For example a 35mm full frame fisheye gives 180 DAOV but 180 x (36/43.27) HAOV (~150) and shows a high degree of elongation distorted at the outer edges. Also your aspect ratio will change, the as you will loose some of the top and bottom of the frame in the transformation. I'd be looking hard to find a fisheye + 67 kit to test out.
