It has been a rule of thumb (some even believe a law of nature) since the dawn of the digital camera era at the turn of the past century, that for the highest possible image quality one needed to use the largest possible sensor…
But then a funny thing started to happen about three or four years ago. Many photographers started to find that they were getting truly excellent image quality from APS-C and Micro Four Thirds cameras. Once pixel count got to about 16 Megapixels, the number of pixels itself stopped being something to pursue just for its own sake.
Of course higher resolution sensors offering 24MP and 36MP allow one to produce larger prints, and crop severely if necessary. But, for most photographers somewhere in the 16-20MP range was sufficient at a practical level.
