The Panasonic Lumix DMC-LX2 also uses a 10-megapixel CCD as the G7 does. There's one significant difference in the implementation, however: the LX2's sensor has a native 16:9 aspect ratio instead of 4:3. To produce 4:3 or 3:2 aspect photos, the LX2 simply uses the relevant fraction of the sensor. This enables the LX2 to produce higher-resolution 16:9 images than would be possible with a standard 10-megapixel sensor. (It would require a 13-megapixel 4:3 aspect sensor to generate 10-megapixel 16:9 images.) Conversely, the resolution of the LX2's 4:3 images is only 7 megapixels.
