Mirko, do you have any sample images, I assume there's a prototype.
There is a small demand for Roundshot style cameras shooting 360º but it really is small, if the actual º that's exposed could be chosen maybe demand might be higher.
Panoramics or rather how do I shoot some of the very wide landscapes I've been working in, has been a dilemma to me for around 25 years. Rotating cameras, Noblex, Horizont etc, produce a unique signature which really didn't suit my work, and 360º cameras just shoot the same but over the full circle.
In the end I chose to buy a 6x17 camera, if I had had the cash at the time I'd have bought a 6x24 (it was the cost of a WA lens for 6x24 that was the issue). While I shoot film for all my own ork I also stitch large panoramas from digital imgaes for commercial work but I prefer the straight images, there's the strange perspective when cameras (or lenses) are rotated whether motorised or stitched image.
Maybe I should add that I'd shoot HD video now to cover some of the wide panoramas
It's a very specialist market and so probably few of us here would be potential customers however there is a sector of the market that use and need cameras with that kind of capability, creating Virtual Reality images. As most will be used/shown digital formats then there's the issue of should the capture be digital or on film.
