That aperture sure is small for a 41MP sensor.

So basically this is their way of giving you a 8MP camera - by increasing the sensor size to get more light and at the same time cramming more MP into it to salvage any last drop of resolution they can get, for detail and PR purposes. And then scale it down.

And they give you the option to take a 38MP image if you don't mind the noise.

To be honest, it's the xenon flash that has my heart.

Twice the power of the N8 xenon flash
Still miss using proper flash on my old C901, the LED on SGS 2 isn't quite the same

Xenon flash never appears on Android phones cos they are all getting so thin. Only one I seen was a HTC with a Xenon Windows phone. But I think this will be good just wish they made another metal clad design. But Symbian Belle is a huge improvement and also having more ram and faster processor is a plus

You didn't hear of the Motorola XT720 back in 2010 which had Xenon running on Android

Right me if i'm wrong but i believe it's because of the operating system, Belle doesn't support resolutions over nHD. It should have had a design language closer to the N9 and WM operating system.

They can port Belle to newer ARM architectures and also higher the display resolution!
But this means every app on Nokia Store will have to be adjusted for this!

And since Symbian now is relegated to a second tier OS, and making its way out of the entire smartphone market in the years to come, going for such a step is just not worth it!

A nice interview with Dinning going through the camera UI at the end..


And here are the full highlights of the Nokia 808 with PureView technology: (make sure you read them all)

- The PureView technology has been developed for the past five years and in parallel with other technologies implemented in recent Nokia camraphones.
- Lossless Zoom: 3x for Stills, 4x for 1080p video, 6x for 720p video, 12x for nHD video.
- Dual modus sensor supporting both aspect ratios: 16:9 at 34 effective MP, and 4:3 at 38 effective MP.
- 26-76 mm zoom range, maintaining same aperture over all the range! This means 3.5 stops advantages enabling up to 6x faster shutter speeds!
- Contrast to optical zooming, distortion is kept at minimal level!
- Zooming is all silent as there are no optical elements moving back and forth. (Important in video capturing)
- The lens is produced at 10x more precision than SLR lenses to cope with the 41 MP sensor!
- The whole camera module is at 50% to 70% less in size compared to similar range zooms!
- Maintain same 15 cm minimal focus distance for the whole zoom range!
- The huge sensor enables a longer focal length of 8.02 mm (equivalent to 26mm and 28mm depending on the aspect ratio), which coupled with the wide F2.4 aperture enables Bokeh effects current compact cameras can't achieve!!!
In comparison, the high-end Canon G12, has a 6.1-30.5 mm equivalent to 28-140 mm, and at F2.8-4.5!!
- The 41 MP 1/1.2" sensor has a native pixel size of 1.4 microns.
- Offering Slide Zoom: Swipe up or down on the viewfinder to automatically adjust the zoom steps and the output resolution of the desired photo!
- Processing at 1000 MP/sec and 16x oversampling than conventional cameras and smartphones!! There is a built-in GPU in the camera module to help in the process!
- Nokia Rich Record: Capture sound at 140-145 db, more than even some professional cameras can achieve, and at minimal distortion levels enabling CD-like quality!!
- Oversampling eliminates Bayern pattern problems which could lead to certain artifacts! Which in turn leads to pure high-quality detailed 5MP photos!

This last statement could be the key that oversampling does indeed beat the bigger photosites approach to better quality!!
This will remain to be tested. Of course some experts will have their say on the issue soon enough. But if turns out to be true, then we can safely claim that Nokia have re-invented digital photography!!

Meanwhile, due to the bigger sensor alone, at 1x zoom and 7-to1 oversampling ratio, the Nokia 808 PureView should be able to outperform any compact digital camera in the market today in terms of IQ! In exception for the freshly announced Canon G1 X which in turn takes another different approach to conventional compact digital photography!
