Recently Canon and Nikon announced successors for their lower price (but still 3k-ish) full frame cameras. The successor of the Nikon D700, the D800, boosts the original 12 megapixels to a whopping 36 megapixels, however Canon made even more impression by boosting the original 21 megapixels of the 5D mkII to an impressive 22 megapixel of the 5D mkIII So people go: what the bleeb is going on here? First question is, wasn't Canon unable to follow the megapixel race? Nope, they patented a 50MP sensor some years ago already, but it hasn't shown up in any camera yet. Also if you consider that they can put 10-14 megapixel in some 4 x 6 mm sensor of pocket cameras then at the same pixel count per area, that would be 360 - 500 megapixel on a full frame. Apparantly there is more to pixel counting that meets the eye and there must be an optimum (sweetspot), but is Nikon right or Canon? Thoughts?
