I shoot with a Sigma 8mm fisheye on a Canon 550D and want to convert the fisheye distortion into a more normal rectilinear-looking image. What software can do this well, preferably with lens profiles or an easy workflow?

Try Panorama Tools - free and very effective: http://panotools.sourceforge.net/

There is a friendly interface to it called PTGUI.

Yes—several tools can do this.
The simplest option is Adobe software that supports lens profiles, such as Lightroom or Adobe Camera Raw. If the Sigma 8mm lens profile is available, enabling lens profile correction can automatically “defish” the image.
Free alternatives include Hugin and Panorama Tools. Panorama Tools is powerful and effective, and Hugin provides a friendlier interface for this kind of lens correction. PTGui is another GUI option built around Panorama Tools workflows.
Keep in mind that converting an 8mm fisheye image to rectilinear stretches the edges heavily, so the result may lose resolution near the frame boundaries and won’t always look natural depending on the subject and framing.
