Nokia stock plunges as new Lumia smartphones fail to impress investors

London - Nokia's share price dropped by over 10 percent as the introduction of two new Lumia smartphones powered by Microsoft's Windows Phone 8 operating system have failed to impress investors.
 
Microsoft and Nokia unveiled the new Lumia 820 and 920 smartphones at a special event in New York today, in a hope that it will help the firm take on Apple and Google in the smartphone war.
 
The embattled firm, however, saw its share price plummet before the announcement had even finished, the Daily Mail reports.
 
An hour after the event began the share price was down 11.48 percent to 2.51 dollars per share, suggesting the tie-up with Microsoft was poorly received.
 
The new Lumia 920 features wireless charging and a 'PureView' camera, which the mobile firm said offered better video and still images than rival smartphones.
 
It also features several Nokia-only functions designed to make it stand out from other Windows Phone 8 devices.
 
The firm claimed that 'floating lens technology' meant the handset could capture up to 10 times the amount of light than other handsets.
