Just how much smaller is it? We have the folks from Mobilport tearing the Lumia 920 apart and physically illustrating just how much smaller the sensor is. We’d need to also mention that the Lumia 920 uses the same size of sensor as do other high-end smartphones like the iPhone 5/4S, the Samsung Galaxy S III and the HTC One X.
How important is the size of the sensor for the quality of images? Even technologies like backside illumination and larger apertures don’t contribute as much to low-light performance as does a simple boost in sensor size. With that in mind, take a look at the sensors of the 808 PureView, and Lumia 920 compared side by side below.
