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.

no it's 1/16 (inv square of 4) so that is 6.25% lol.  I was just wondering if they use some kind of AI algorithms to make good predictions on what the data should look like vs what superzoom cameras like the Nikon P900/950/1000 do.

In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military industrial complex. The potential for the disastrous rise of misplaced power exists and will persist. We must never let the weight of this combination endanger our liberties or democratic processes. We should take nothing for granted. Only an alert and knowledgeable citizenry can compel the proper meshing of the huge industrial and military machinery of defense with our peaceful methods and goals, so that security and liberty may prosper together.
