Wide angles lenses on Canon full frame versus 1.6 x field of view cropping cameras
Comparison of various wide angles on full frame versus Canon EOS D30 / D60 / 10D / 300D / 20D.
All images are from Canon Lens Works II. The 15 mm fish eye + PanoTools images have been rectilinearized or converted to QVTR panorama using Panorama Tools developed by Helmut Dersch. The 17 mm images are crops of the 14 mm images (no 17 mm sample available in Canon Lens Works II).
The 15 mm fish eye + PanoTools gives a horizontal coverage on the Canon D30/D60/10D/300D/20D corresponding to a 17 mm lens on a full frame 24x36 camera and a vertical coverage corresponding to a 20 mm lens.
