[QUOTE="Spottydumplings, post: 557021, member: 39844"] The article is fairly generic and does not mention pixel densities etc.. The preceding sentence states: "[I]Since the light intensity is the same (per square mm), the Full Frame camera will receive four times as much light as the Four Thirds camera, during those exposures, because it has four times the sensor area, all experiencing that same intensity.[/I]" I have read in other posts that the size of the photosites has an effect on noise but if that is the case, [I]to a certain level,[/I] should my D90 not be able to match a 24MP FF camera and exceed that of a 36MP D800 as the photosites will be the same size or larger (obviously only for shot noise)?
