For an ultra-wide, I really love the 15mm f/2.8 fisheye. I'm probably going to buy one off the used market. My DxO Optics Pro software will take a fish eye perspective and convert it to rectilinear. It's incredible for tight interiors or subjects that you have to shoot really close to. I haven't really tried it for scenics. Today, I'd do a multi-shot pano for a scenic that wide, but I'd be curious to try it with the 15mm and correct for the distortion.
Interesting. I am quite the fan of sigma lenses.. I was also considering the 14mm canon.. But I'm not sure if the extra 2 mm is worth it for the price over the 16-35!
