Q. I see the new Nokia E55 and E52 have an EdoF camera. What is EdoF?
A. Standing for Extended Depth of Field, this fixed focus camera has a specially malformed lens, such that the Red, Green and Blue components of the image are focussed at different points. Special software algorithms then combine the R, G and B 'images' to produce a composite that's effectively in focus from a metre away to infinity.
