You do understand what megapixels are dont you? The more you have then basically the bigger the image.
My super pro DSLR (yes, I am a photographer). shoots at 22mp. Are you telling me that the Lumia is better because it has more? No, the problem with the Lumia is that to fit that many MP onto a small sensor they have to be small pixels. Small is not very good, especially in low light.
If the technology was that good, why dont they include it on all the other Lumia phones in their lineup?
Heres a shocking bit of info that I know will cause many here to curse me as the devil.... Ready???? Your camera phone.... is never going to be as good as a pro DSLR... OMG I SAID IT!! Its good for taking on holiday and snapping pictures of your penis to send to your lady friend.
Boy are you off the deep end. The 1020 is the first WP phone with the big camera, 808 was the first. How would Nokia offer a retro fit kit for its older models? Stop thinking about our penises, don't be that guy. If you really are a lens smith then check out Smugmug hosting site, so many crappy IPhone pictures. No penises though, don't be disappointed.
