Damian Dinning narrates the Nokia 808 PureView story - noisy optical zoom phone prototypes to blame
Nokia's camera guru Damian Dinning finally spilled the beans how the company got to the mammoth 41MP Nokia 808 PureView handset. We have been hearing for a while that Nokia has prototypes with giant image sensors in its labs, but now Mr Dinning himself confirms that the company has been toying around with the idea for the last 4-5 years.

Apparently the long-rumored optical zoom Nokia phone existed in various prototype forms since 2006. It's precisely the disadvantages of folding optical zoom lens for image quality that pushed Nokia to pursue another angle with which to solve the lossless zoom puzzle in compact devices like smartphones.

Even the most compact optical zoom modules introduced unacceptable bulk to the prototype devices, diminished image sharpness and introduced noise while zooming in videos. Around that time Nokia created its Camera Simulation Environment, allowing it to virtually test different optics, sensor materials and shooting scenarios. A Nokia engineer shared over lunch with his camera buddies that he read an interesting article how satellite images are taken with a giant sensor, then we only see a small portion of that image, which keeps an amazing level of detail, as if zooming in without losing quality.

Long story short, this idea resurfaced after a ten-hour engineers' meeting in a Tokyo hotel bar, and Nokia decided to solve the zooming issue another way, getting together with the Carl Zeiss optics people, as well as reps from the camera modules and materials companies it has been working with to crack the conundrum. Damian dinning reflects on those times:
I remember the content of two emails still to this day. One from the Tampere team with images attached captured with the first prototype camera and another captured with a Canon digital SLR as a reference. I opened both images and viewed immediately at 100%. Initially, I thought the images were labelled wrongly. Then I also saw the email from Carl Zeiss with the results from the lab testing. It’s usual for Carl Zeiss to provide a list of comments on areas where improvements could be made. On this occasion however, the email was uncharacteristically short. Here’s a short unedited excerpt from that email: “Our lab people are VERY happy with the quality.”
It all resulted in the PureView Pro technology we witnessed last week in the Nokia 808 PureView with its Rich Recording audio, and will likely be developed further into other flagship cameraphones from Nokia, eventually making its way to Nokia Windows Phones as well.

I enjoy the camera wars more than the "core" wars.

Core war is useless... I really enjoyed the Sony Ericsson - Nokia fight era where the great products were born...e.g. The Cybershot and Walkman series versus the N series .....
Something went horribly wrong in the last few years and now we are only shouting about RAM and Cores etc, design philosophy was lost.
I still enjoy watching the Motorola RAZR(original one), the Nokia N91/N93, SE K880 etc.....
I am really hoping that era returns....

Pureview and Windows Phone 8 would be a great pair

Articles like these make me wish I worked at Nokia.
