Late night musing minds want to know.... >jm Depth of field remains the same no mater what size the "targett" is, be it full frame 35mm or 1.5 ratio or as in this case 1.6 ratio. When this lens is mounted on a full frame 35mm it produces an almost circular image, slight flat area on top and bottom of a horizontal 35mm frame. In the Canon 20D with its 1.6 ratio only the corners of the frame are cut, I usually crop this out. As far as it being a fisheye, fisheye lenses are designed to distort and the distortion is still there.
