CIZ is digital zoom, right? So the original 36 MP resolution becomes ~2 MP.

No, CIZ is a 'pattern enhancer'. It extrapolates the image information by using heuristics, and it can work surprisingly well. Some times it fails, but often it does work almost as good as high-end up-samplling software programs do - those do not extrapolate, but 'add' new data.

Arn't you just splitting hairs here? It might be very good at it, but ultimately, its just a mechanism for taking less information and programmatically filling in the blanks. Its still a digital zoom. Its just a somewhat smarter one.

On a related note, how do high-end up-sampling programs "add" new data?
