If you thought a bigger pixel count just meant bigger file sizes, then take a look above. That big guy at the bottom is the 41-megapixel sensor we saw unsheathed in our hands on, and responsible for those awesome Nokia 808 PureView shots we saw at MWC on Monday. The two above it are 8- and 5-megapixel sensors respectively, and give you an idea of the real-estate cost of packing a superior snapper. At two and a half times the physical size of the N8's prized optics, we think the PureView system earns its title as the biggest thing in mobile imaging somewhat convincingly.
Update: In case you're still confused, one of Nokia's chief camera experts Damian Dinning gives a thorough walkthrough of the technology in our Engadget interview. There's also a Nokia video after the break.
