"Its barrel heavily occludes/shades images shot at distances greater than 3 metres. Depending on the light, the corners turn either white or black. As a result, this lens is useless for landscape, architecture, and most portraiture." - unthinkable that they would be releasing it this way. I can understand that there are other lenses with somewhat similar issues - like the Canon 8-15 fisheye that is not exactly useful at - say - 9mm, but this still seems rather pathetic to me.
