Nokia 808 PureView lens and sensor specifications

The latest Nokia 808 PureView With 41 Mega pixel camera

The first thing to realize is that this isn't a standard 1/3.2" mobile phone sensor, it's an unusual and remarkably large 1/1.2" type (five times larger). In fact, it's almost three times the size of the sensors in most compact cameras. 

As a result, its photosites are the same size as those in most 8.2MP cameraphone but the 808 doesn't try to create an image of the same quality, 5 times bigger. Instead it oversamples the image and then pixel-bins (using proprietary algorithms Nokia says optimize detail retention) down to a smaller size (though there is a special 'creative' shooting mode if you want the full resolution - 38MP at 4:3 aspect ratio, 36MP at 16:9).
