Re: iPhone 5S beats 1020 in low light photography ??
Good for Apple. While they're cameras might not be the best, one thing I absolutely admire is what amazing results they produce without making the user get down and dirty (and how fast too, I always envy how my iPhone friends can repeatedly tap the shutter button to take photos [and with iOS7, they just tap and hold to take a high speed shutter of the scene]). And we mustn't forget that admittedly clever flash technology.
So good work for Apple. But as others have said: without flash, the Lumia 1020 would kick-***. We also mustn't forget: the Lumia 1020 is meant for enthusiast photographers and up. Amateurs and novices aren't going to get the same results. Auto works, but with cameras of this tier (DSLR, I mean), you will only get GREAT results when you adjust the settings yourself.
So auto will provide good results, above average when compared to others phones. But you only achieve the 1020's real potential when you take the time to get those settings just right.
So in conclusion, for my mini essay: Apple and Nokia are, what I would consider, the mobile photography titans, but in their own way. Apple rules in the sense it creates above-average photos (but still not Nokia quality), without making the user have to put any thought into it. They can reliably produce great shots without even needing to know about shutter speed, exposure value, white balance, etc. Meanwhile, Nokia is king in true lowlight (I.E: no flash to help out), and in overall quality. However, for you to get such amazing results with a Nokia, you've got to work for it. Automatic will typically produce above average results (maybe not as good as Apple's automatic, however), but once the user goes manual, Nokia blows other smartphone cameras out the water.
So yes, Apple and Nokia are the photography kings, they just have different ways of achieving it.
