DESC: The Olympus EVOLT E-330 offers something a lot of people have been hoping for. Taking advantage of how far the price of image sensors has fallen, the E-330 features not one, but two sensors. The first is an NMOS sensor with a resolution of 7.5 megapixels, which is used for image capture. The second sensor is a CCD of unknown resolution, which is used to allow a live preview image on the camera's LCD display.
