According to Fujifilm.jp web site, they don't make it in 120/220. Only 35mm.

The Natura S aperture does stop down, but I don't know any details. I assume that Ryuji can answer this better than I can, because he has referred to his fall-off tests at f/4. The maximum shutter speed is only 1/360 as far as I know (source: Dirk Rosler of megaperls).
Fuji does not publish the minimum aperture, but according to its published exposure program plot, the camera stops down to f/18.3. The fastest shutter speed is 1/360 sec, as you said.

As I mentioned before, this camera relies on wide latitude of color negative films in taking flashless pictures indoors and outdoors. I agree this is probably not for everyone, but I certainly see why this camera is so attractive.
