I just was pointed to a video PocketNow published yesterday in which their editor Michael Fisher (on Twitter as well) gives an interesting comparison between the Nokia 808 PureView and the Nokia Lumia 1020. Some time ago, he published an extensive review of the Lumia 1020 you might want to read as well.
I’m not saying I agree with everything he writes, but I found it all in all good enough to bring it under your attention. Wish I had the time to realize a video like this, but I don’t – so I’ll share his one here. Enjoy! :-)
