I sometimes leave the house with just one lens - just for fun. It is rarely the Nikon 10.5 DX Fisheye though. Went to the Concourse here in Northeast Kansas City. Built in 1907-08 and designed by architect Henry Wright - a partner of George Kessler - it graces a prominent western location on The Concourse. The fish-eye-so named for it's kind of distortion-is not terribly practical. But it is very sharp and fun to use in some circumstances. It's major distortion was corrected in Photoshop..but much remains.
Above is an image of The Colonnade not long after it was constructed ca1908. The view is west from Gladstone Boulevard.
