I saw Sony's alpha cameras have a 2x "smart" digital zoom and a 4x option, I wonder what the difference is (other than the magnitude of the magnification) and how Sony's 2x "smart" digital zoom compares to Olympus's 2x

2x uses the central 25% of the pixels so 4x would use the central 12.5% of the pixels.  Wait, is that right?  12.5%?

I'm sorry, I do not know the answer to your question. Probably a bit of searching will find the answer though. I suspect that Olympus, Sony, etc. when doing in-camera uprezzing do it on the raw data so it is possible they get slightly better results than doing it later on a computer using a regular tiff or jpeg file.
