I m thinking to buy a new a lumia...I m confused whether to buy a lumia 730 or lumia 640.... I m looking for a camera phone...I know that lumia 730 has carl zeiss lens and also an aperture of 1.9 so i guess technically lumia 730's camera would be better but the problem is will it ever get lumia camera 5.0? As it has better algorithms for low light, rich capture etc etc..
