Most newer dSLR cameras have expandable ISO ranges now. 6400 is the max native ISO which means it's the highest this camera can get before image quality is sacrificed as per the manufacturer. The ISO can be set using ISO Speed in the menu options. It has options from Auto and then from 100-6400 natively. The user can manually select higher ISO's from 6400, 8000, 10000 and finally 12800. Given the camera is overextending in it's ISO performance, the sensor will struggle to get enough light to it - especially going from 6400 to 12800. This causes the image to be poorly processed which make the image look grainy or noisy in most circumstances. Given the right variables including light and lenses, advanced photographers can utilize higher ISO's without loosing too much quality in the image. For the everyday/entry user, the camera utilizes the native resolution to help the camera be more automatic.
