There's no guarantee that this video is genuine - it could conceivably be based on renders - but hey, let's assume it's kosher for now...
The Nokia 9 PureView will have five ZEISS cameras. The ad talks about 'Impossible Detail', '5 Simultaneous Shots', '10x more light captured', 'Incredible Texture', and 'Stunning crisp HDR photography'. Plus, as you'd expect, you can refocus after the fact. Interestingly, there's no mention of zoom capability, and I wonder - I just wonder - whether the way the renders are done is accurate and that all five cameras are identical. In other words, it's doing in hardware very much what Google is doing in software in the Pixel range, i.e. taking five 'identical' shots and then combining them for maximum detail and minimal noise. With that facility to focus at least one of the lenses differently in some modes, for the 'refocus' feature.
All rather interesting. Anyone looking forward to a Nokia 9/ Lumia 950 head to head?(!)
Away from imaging, the Nokia 9 PureView will have a notch-less 5.99-inch 2K (QHD) 'PureDisplay' with HDR10 support, plus an in-display fingerprint scanner. It will be powered by a Snapdragon 845 chipset with 6GB of RAM and it will come with 128GB of built-in storage:
The Nokia 9 PureView will have Qi wireless charging and will run Android One, based on Android 9, making it very 'stock' and also guaranteed updates.
Take all this with a pinch of salt anyway, but whatever happens, it's great to see the PureView brand back in use officially again!
