More about the sensor and the lens is "a community for enthusiast photographers". I was not aware it existed, but today it published a nice review of the Nokia 808 PureView, zooming in on the camera sensor and the lens.

The author is remarkably enthusiastic about the Nokia 808 and I'm not surprised :-) What did surprise me a bit he (or she?) is using a lot of the pictures Nokia provided months ago, but that won't spoil your time reading the article itself I guess :-)
