Did it ever occur to you that the megapixel rating for your camera is based on its native aspect ratio? A full frame camera with an aspect ratio of 3:2 will discard 12% of those if you print using a 4:3 aspect ratio. A full frame camera with an aspect ratio of 3:2 will discard 33% of the pixels if you print using a square aspect ratio. Essentially, your 44 megapixel camera becomes a 29 megapixel camera if you shoot a square format image. Does it matter? Probably not - - but this does help put the megapixel madness in perspective.
