The Lumia 1020's optically stabilized 41MP image sensor that can snap
40MP and 5MP photos at the same time – one straight off the sensor and
one after Nokia's Super sampling has been applied. The other 41MP
cameraphone - 808 PureView can only shoot one or the other at a time.
To make the best out of this beast of a camera, the Nokia ships the
Lumia 1020 with its Pro Camera and Smart Camera camera lens apps.
They'll allow advanced users fiddle with the camera settings and get the
most out of the impressive shooter - there's even a full manual mode,
which is a rarity outside prosumer or pro-grade cameras. At the front,
there's a secondary 1.2MP wide-angle camera.
