Afternoon all, now Christmas is over I'm starting my research into the first additional lens for the new camera. I know I will use wide-angle a lot more than telephoto, so this is where I'm starting. This lens will be aimed at indoor shots, outdoor, landscape and as a great general all-rounder. It will be mounted on a Sony A65 and I don't want to buy a lens that suffers from distortion, eg "fisheye". Having seen many photo's taken on the Sigma 10-20mm and read a few reviews this seems like a good starting place. Are there any other options you'd recommend ? And why do there seem to be no very wide angle prime lenses ?
