A friend of mine just purchased a Panasonic LX3 camera, and in the manual it says that the sensor size is 1/1.63". He's always known sensor size by the actual physical size of the sensor (height & width). Anyone know the actual physical size of the sensor, or is it actually 1" x 1.63"? We figure that just doesn't sound correct. Did a Google, but only came up with the original number I posted.
