After many months of tinkering I finally have a panorama-head robot that creates panoramas with my Sigma DP1. If you don’t know about Sigmas, they are cameras that will drive you mad, especially if you’re used to the polished software/firmware of a Canon or Nikon. For example, the DP1 won’t turn on unless you remove the lens-cap.
The most well-known robotic panorama head is the GigaPan. At the time I started building my own, they were selling for under $300. For what they do, that was (is) very cheap. But I didn’t like the fact that I couldn’t modify the Gigapan or control it from my PC. I also didn’t want a panohead that had weight limitations.
