Anyone here using a Gigapan system with an Olympus OMD? I'm thinking of getting one, but I'm confused about the models. According to Gigapan, the model I'd need would be their EPIC-Pro--which is $800+. According to their specifications, however, it looks like the EPIC 100 would work just fine, and is about half the price. Obviously I'd prefer the smaller, lighter model . . . if it fits. Anyone?
