All right, I'm looking for a nice wide lens for landscapes and small spaces, etc. The Pentax DA 10-17mm f/3.5 Fisheye would be a fun lens to have, especially for tight spaces and fun pictures. I think that the FE effect would get tiresome soon, and the lens would be more specialized than I need in a lens right now. Additionally, I get nervous that the lens glass is completely exposed and can't be protected by a filter.
Sigma also makes a lens that would work for me in this situation. The 10-20mm f/4 wide angle will also shoot tight spaces and would be excellent on landscapes and nature shots. It doesn't feature the line-bending that the Fisheye does, but I think this lens would ultimately be more practical.
Anyone have experience with or opinions about these lenses?
Thanks!
