Nice shots with good color depth. I like the latitude the 10-20mm provides. Easy to get used to getting in closer to larger objects and the distortion, taken advantage of properly, can produce quite pleasing effects at least in regard to landscapes.
Well it defenitly takes some work to make the pictures look normal and not distorted. This really becomes a problem when you taking picture shots becuase if theres a face in the corner it kinda gets "sucked" off the side of the picture
Example:
No he had some bad hair, but it wasnt as bad as it looks here
I like it for landscapes, but that's just about all I shoot. If I use it for buildings I try to take best advantage of the distortion. I think if I were to shoot people or not want distortion I'd change to a bit different lens.
