    The basic principle of having a high res sensor is that in good light you can get a very high resolution shot or a cropped/zoomed shot . In lower res you can get a lot of noise reduction in low light and in good light an oversampled image is pinpoint, I have found this to be the case with the 808, most of my "pureview" shots come of great first time, whilst the full res ones have stupid levels of details.
    Really not a photographer but getting in to it a bit, but I do have some knowledge of dsp so the principle makes sense to me.

    I've had a skim throught the whitepaper, will read properly when I get a chance (http://i.nokia.com/blob/view/-/27238...whitepaper.pdf)

    I've put up a few in photobucket if anyone wants to see what full res photos taken by a very amateurish person looks like

    So they claim using the manual focus we should get some bokeh. Hmmm.... They have gone for a wider aperture than the 808 had. But without knowing all the details I can't calculate the effective DoF to see the change. Their sample picture looks nice.

    Looking in to the dual capture thing int he whitepaper is a neat trick that solves something that bugs me on the 808.
    Effectively because you save 2 pics, you don't have to faff around deciding what resolution to use, when trying to capture a smaller object on the 808 you can just take a full res and crop it manually but sometimes that makes it tricky to see on the screen, now you zoom in, it takes the cropped image and saves the full image on top of that, so really it allows to frame the image when taking it, but you can reframe later if it's not quite right. Obviously in that scenario you lose some of the oversampling goodness.
