The Nokia's pixels by my calcs are ~1.44 microns which is a little larger than an iPhone 5's pixels (~1.4 microns). The Nokia sensor has around 5.5x the surface area of the iPhone 5 but only 5.125x the resolution. So basically the Nokia's advantage is having both a high quantity of pixels and having larger pixels.
