This may be a big surprise to many but contrary to what camera manufacters like consumers to beleive MegaPixels DO NOT relate the the quality of an image, mearly its size, megapixel simple means "1000 pixels", it tells nothing of the actual quality of the image. While this is well known to people into photography its still widely beleived by consumers.
