Dr. Bob,
I have too have a Canon 5d and have used it extensively for making 360 panos.
You can see samples of my work at
http://www.panoplanet.net/ and http://panoplanet.net/synagogues/
The 5d is an excellent body for our pano purposes. With respect to lens choice, I first bought a Canon 15mm f2.8 lens. With that lens I take about 8 or 9 shots to get a full 360 plus one for the zenith and one for the nadir. I stitch and blend my images using PTGui and use a Nodal Ninja pano head to hold the camera on the tripod.
After taking many panos of buildings I became interested in taking panos which include people. I felt that panos with moving subjects would be easier if I could take the set of images more quickly. In order to be quicker I bought a Sigma 8mm f3.5 fisheye lens which allows me to shoot a full 360 with only 3 or 4 shots plus one for the zenith and one for the nadir.
The fisheye Sigma definitely achieves 360 coverage with about half the shots required by the Canon 15mm. That said, I find that I tend to use the Sigma less than the Canon, usually where speed is important such as crowd shots. After considerable comparison testing I find the Canon lens yields brighter and sharper images. Additionally, there is a difference in the way the two lenses work in the D5 viewfinder. Scenes appear normally when viewed through the D5?s viewfinder with a Canon 15mm attached (normally, with a bit of warping for the wide angle). Scenes appear in a large round fisheye form, a kind of a globe, when viewed through the D5?s viewfinder with a Sigma fisheye attached.
Perhaps these comments will get you started. Essentially, if budget or speed is your concern, the Sigma is the answer. When quality is paramount the Canon lens has given me the best results. That?s not to say the Sigma doesn?t achieve a high quality result. It does. But, careful comparison has shown me the Canon is better.
If I can be of any further assistance don?t hesitate to get in touch.

By the way, taking panos is less critical than you?d expect. I?ve taken a good many with my wife?s pocket point and shoot. I just hand-hold the camera level and shoot multiple images while turning on one heel. Here?s an example: http://www.panoplanet.net/orient/ueno_paddleboats.htm

Visited your site. Great images!!
I am a total beginner. I recently purchased a Canon 5d.
Can you please recommend a lens and software for me to make similar
pictures?
Thanks,
