And what noise is, is basically there is a processor in there that takes from the lens, the light and then it converts it into an image. Well nowadays that's called an "engine", and that engine, they all produce noise. And noise is generally a purple pixels on the edges of things depending on the lighting situation. Well, when you have something like a major brand, like Canon, Nikon, Olympus, Pentax, Panasonic, then you're going to have generally a possibility for a lower amount of noise in your pictures.
