What about a 60D or 7D with an ulta wide EF lens? 14mm.....That would get me down to 22mm crop.
Great.
It's probably best to narrow down what camera you want first, then decide on the lens. The 3 that you're talking about a different cameras and FF and crop will have lenses for what you want to do.
Pick a camera based on the camera, not on the lenses. Thats just my 2 cents
