24 MP from an entry level DSLR

My calculations are not 'way off', I have proven them to the individual pixel two ways. The method you cited is so oversimplified as to be ridiculous as well as 'way off'. How can you remove 1/3 of 12mp but it only really removes less than 1/2 megapixel? Answer: do the math entirely wrong with a faulty formula, and don't question something that on its face is suspect.

No, I have shown why your claim of 406272 is grossly over-simplified. My sketch plainly showed where that incorrect number comes from and why it is incorrect. It's not rocket science. It's just common sense. The formula you cited was oversimplified and resulted in a nonsense answer, plain and simple. Why cling to something that's been shown to be wrong?

Up-sampling 12 mp to 18 mp does not produce 18 mp worth of image data. Yes, more MP is a marketing gimmick at sensor sizes where they cram too many pixels on a small sensor. I agree with you on that. However - 18mp on my new(er) Canon will allow me to do crops that my 12mp Canon suffered under.
