Say what?!?!
Aside from the low lit shot (one still looks better though), the one looks considerably better in all of them:
- amount of detail captured in the flower, not to mention colours
- the portrait shot is a hundred times better, just look at the face and amount of light, the iphone 5 looks to have a bit more detail/sharper look to it
- the colours in the test lab when well lit, iphone 5 has a warm yellow tinge, blurry and rather noisy/grainy looking, the one has true whites and looks clearer with better colours
- outdoor shot, just look at the grass, colours and bushes etc., iphone looks too warm and again very blurry in comparison
Plus don't forget, that a software update could improve the shots even more (especially the low lit shot as that is very poor, should do better) just like what happened with the lumia 920 (a lot of review sites slated it for not being better, photo quality was very inconsistent), the GS 3 and the small camera update not long after release that vastly improved quality and then the htc one mobiles with sense V4+
No idea how on earth you can think that there isn't much difference between them......
EDIT:
Just looking at them again and I still can't believe you think that!
