    I'm very interested in the digital zoom, that I assume is available on the 808 PureView, and that will be available on the Lumia 1020 as well. Is there a website that shows how it works and examples of pictures taken? Or do any of you here on the forum have examples? I'd like to see how good the digital zoom performs.

    Thank you!

    One thing to keep in mind is that digital zoom generally does no more than you can do in PhotoShop unlike optical zoom.

    With optical zoom you actually get additional picture detail, while digital zoom is the same detail enlarged.

    In other words I would not keep hopes too high for any digital zoom as the focal length remains fixed...

    The above poster is right. But it is a good improvement in smartphone cameras at least

    Though you are still not enlarging 5MP to a pixel mess, but you are zooming in that 38MP sensor. You will lose oversampling, but other than that. Coming from 808 owner I love the smooth video zooming on 808.

    Some examples after 5min.

    Yes, the more you zoom, the less pixels are combined.

    The most impressive thing for me is the fact that they are using all available pixels when recording video.. almost all other phones (except the N8) use only part of all the pixels coming from the sensor

    http://falklumo.blogspot.com/2012/03...ew-part-i.html

    "All still photo cameras have the problem that the sensor has many more pixels than there are in HD video. But it is hard to read out all pixels of a still image (10 MP or more) 24, 25, 30 or even 60 times a second. Therefore, still cameras only read a small fraction of its pixels to make the video stream, known as subsampling or line skipping. The effect is a significant degradation of image quality in video mode: there is noise, line flicker, color moiré and the result is no match for HD content produced with so called 4k cameras or cameras with supersampling such as the Canon C300. Such cameras cost $15,000 or more (a notworthy exception is the Panasonic GH2 though which made it the camera of choice for serious video work on a budget).

    And what shall I say? The iCamera does it too, not supersampling 8MP (C300) or 16MP (GH2) but supersampling all 33,593,616 pixels (16:9) 30 times every second! That's one billion pixels the iCamera processes every second. In a mobile phone. This is crazy!"
