When you bought your smartphone, was the quality of the camera a consideration? No? We thought not. If the camera quality were the deciding factor, everyone would be carrying the Nokia Lumia. It is the king of the phone cameras and this month it became even more regal in its specifications.

The rollout of the latest operating system for the Nokia Windows phones, called Black, brings with it the capability of recording images RAW in all their 41-megapixel glory.

The RAW mode that Nokia has sensibly chosen is Adobe's universal digital negative format, DNG. This is the icing on what was already an impressive cake. The Nokia can now record in 38 megapixel jpeg (depending on the aspect ratio), five megapixel down-sampled jpeg, or DNG.

The Nokia camera module, created in collaboration with Zeiss, includes a larger than normal sensor, a six-element f2.2 lens, with image stabilisation achieved by moving the entire lens assembly barrel. Because of the extraordinary pixel density, digital zooming is possible either in camera or in computer processing, without loss of detail up to at least 3X.
