Super-shooter smartphone stand-off

Nokia's Lumia 1020 has gone on sale in the UK.
The Windows Phone handset is distinguished by its 41 megapixel camera, which the firm says captures more detail than any other handset has done before.
But the phone faces a challenge for super-shooter supremacy from Sony.
The Japanese firm's Android-powered Xperia Z1 comes out later this month. Its image sensor has about half the number of megapixels, but Sony claims it produces better photos.
BBC Click's Dan Simmons road tested both ahead of their release to see how they compared.
Click will have more from Berlin's Ifa tech show on this week's programme.
