I've read on this forum that the sensor is rated at something like ISO 400 or 500 and is fixed at that value. Correct me if I'm wrong, but won't this pose limitations in terms of low-light cinematography? I've shot RAW on Nikon DSLRs, and it's a fact that, despite the exposure latitude and general malleability of a RAW image, something shot in the absolute dead of night at ISO 500 is going to be a lot less properly exposed / usable than something shot at ISO 1600 or 3200. Again, I may be missing something crucial here, but if not, what are people's thoughts? Is this a deal-breaking limitation?

Other than this, I adore the idea of this camera. It's small size, the 2/3" CCD, different mount options, RAW 1080p video (of course), the price -- it seems wonderful. The fixed ISO seems odd to me, though. The NIkon D3s can shoot all the way up to ISO 102400 -- and the image is actually usable all the way through, more or less. How can the A-cam dII, with an ISO rating of 500, compete with that in terms of low light (or any number of other HD cameras with multiple high-ISO options)?
