Nokia reveals 41MP cameraphone
A 41-megapixel Nokia smartphone was among the new technology on show during the opening day of Mobile World Congress in Barcelona.
The 808 Pureview offers enhanced low-light performance as well as sophisticated image compression designed to help users share pictures.
Nokia hopes to regain ground lost to Google and Apple in the mobile market.
However, some have criticised Nokia's decision to use its own operating system, Symbian, on the device.
Nokia's other smartphones typically run on Microsoft's Windows Phone software.
Symbian, which first appeared on Nokia phones in the 90s, is widely regarded as inferior to the app and social media-driven Windows Phone system.
"The Pureview 808's Symbian Belle operating system might detract from its appeal to a broader market, where it deserves recognition," said Tony Cripps, a principal analyst with Ovum.
"It's a pity that Nokia was unable to combine the photographic prowess of the PureView 808 with the style of the Lumia 900.
"Such a device may well have been the first smartphone to truly deserve the title of 'superphone'."
'Breathtaking'
Nokia claims the 808 sets a "new industry standard" in mobile imaging devices.
"People will inevitably focus on the 41 megapixel sensor," said Jo Harlow, executive vice-president of Nokia smart devices.
"But the real quantum leap is how the pixels are used to deliver breathtaking image quality at any resolution and the freedom it provides to choose the story you want to tell."
The BBC's technology correspondent Rory Cellan-Jones said he expected some consumers would be surprised over the choice of platform.
"Nokia's put this on a Symbian phone, which will seem strange to people," he said.
"It's also pretty chunky, pretty heavy - but it does take amazing pictures."
China push
Also on show were new models in the company's Lumia range - including the 610, a cheaper device aimed at a "younger audience".
The firm also announced it plans to make the Lumia available in China "in the coming months".
Nokia's chief executive Stephen Elop said that introducing the cameraphone and entry-level smartphone were "the actions necessary to improve the fortunes of Nokia".
Once the mobile world's dominant player, Nokia has struggled to compete as sales of Google and Apple devices have soared in recent years.
Last month Nokia announced it was to stop manufacturing mobile phones in Europe, instead relocating to Asia at a cost of 4,000 jobs.
