My lenses start at 28mm range, and I am looking for a wider angle lens.
At first glance, the 17-40L f4 seems to be the answer, but I am not sure the 17mm is wide enough. I am not looking for Fisheye, but rather a nice wide angle, for interior photos (when you want to showcase a newly decorated room, for example). My only doubt with this Canon, is that 17mm at 1.6 is about 28mm. And I do remember 28mm in film was not the widest you could get without going Fisheye.
I remember seeing a 10-22 somewhere. I am not sure if that will be too wide, I have not used one in quite a while.
What do you use, and do you like it?... It would also help me if you could post the usual 800x800 image at your favorite wide range (say 17mm at 1.6 crop), to help illustrate the distortion, and visual of the focal range.
