I had been thinking about getting a Clauss,
Edit ... the picture that is obviously distorted and looks awful is the set-up shot, at the top of the Clauss web page, not the copy they produced. sorry for any confusion caused. The pano software would compensate for the distortion in the pano shots, so it would not be obvious in the copy, ... but it would result in loss of res.
Would a shift-and stitch image not have been better? /edit - for large pictures you would need to move and stitch.
I suppose the distortion (or projection) depends on the software and mode, but you would like to imagine that these people know what they are doing and are getting the best out of the kit.
Would a Hasselblad (or Phase) 60 with a 300mm lens been a better choice? /edit - if you were going to use pano... resulting in fewer pixels but perhaps comparable res.
