I'm looking for a replacement for my 620 and can't decide between 640 and 830. I like the look of 830 better, it has a dedicated camera button (which is a big plus) and also a better camera. On the other hand, the 640 is way cheaper. Both of them have Lumia Camera 5. I know that the 830 supports RAW, but does the 640?
