It is true that Nokia creates the best camera smartphone but saying that DSLR should say goodbye? That is indeed very debatable.
Since the PureView 808, Nokia made a stand regarding the megapixel race. A 41-megapixel in a phone chassis, even though fat, is a great achievement. Even until now, the PureView 808 is a very capable camera phone despite running on an obsolete software.
Incorporating Windows Phone 8 and Optical Image Stabilization plus newer hardware made the Nokia Lumia 1020 a worthy successor. Don’t forget the Lumia Black update that makes its image algorithms better. So can it replace your DLSR when travelling?
