I visited a few Chicago locations to test my new Sigma 15mm fisheye lens.

First up was the Fourth Presbyterian Church on Michigan Avenue. I deleted those fisheye images since I didn't like the extreme distortion of the vertical lines for this particular subject. I found the Nikon 14-24mm lens more to my liking for this photo shoot:

Next up was Water Tower Place. The fisheye certainly brought more content into the frame:

My last stop of the afternoon was the Museum of Contemporary Art. The fisheye really came in handy for this location. The extremely wide perspective (180 degrees) of this lens enabled me to capture images of the staircase that otherwise would not have been possible:

I expect the fisheye lens to be a highly specialized lens--one that isn't suitable for 99% of my pictures. But, for the 1% of situations where the fisheye shines, there isn't any other lens that will fit the bill. If nothing else, it's going to be a lot of fun.
