Topside the 18-35mm or the 20mm on film and the 12-24mm on the DX sensor, would be the substitutes for the fisheyes... Though I heard some people say "Theres NO use for the fisheye on land..." I would prefer, "They are not what they are UW, but they are a differential for sure." I have even seen G-R-E-A-T wedding pics taken with a 16mm fisheye.
