They look good. The question is, does this lens perform better than the kit at 19mm? It is faster but it seems to me that it's very comparable to the G3 kit lens. I also noticed on the third image a slight barrel distortion at the bottom center.

Yes, indeed, I can see it. I think most wide angle lenses have some problems of that nature. It becomes more noticeable when there is a big contrast in colors. Take a look at the attached picture, it doesn't appear as bad as the the third pictures above.

I don't think that barrel distortion is more evident because of the color saturation. I think the evidence appears when you have straight lines close to the edges of the image (whether it's a building or a lamppost on the sides or the horizon, street line, sidewalk, etc. at the bottom).

those look good (though realllllly blue on my work monitor here). I wonder how much of a difference there really is between this lens and the 20 in bright light. Probably not much.

Except for the 1mm extra "reach," haha.

It may perform better than the 20mm in bright light because the 20mm tends to over expose in high contrast situations. I don't know how the Sigma handles that.

I haven't had that problem yet, but then again it's been pretty dark and dreary since I picked mine up. You gotta love winter in Pittsburgh.

I always had a hard time controlling highlight clipping with the 20mm. I had to decrease the exposure so much that the image would go very very dark (and consequently, noisy). So, I got tired of dealing with it and got rid of it. I think I'm the only one in the world who has done that...
