>With half the megapixels, the Xperia Z1 produces better, more detailed pictures in the real world according to reviews.
Which reviews? I read up on the Z1 when it was released and whilst it looks to be a damned fine handset, I don't recall any reviewers being amazed by its camera. However, the Z1 does take better pictures underwater than the Nokia, on account of the Nokia not being waterproof.
Nokia's approach takes a nice and simple approach based on the observation that most zoom photographs are taken during the day (landmarks, sports) and most low-light photos are taken at wide angle (indoors, parties, street scenes), so either cropping or interpolation is used accordingly.
If the Z1's camera were that good, Sony wouldn't bothering with their 'Smart Lens' (basically the lens and sensor - but not the screen - from one of two of Sony's existing compact cameras, one of which, the RX100 M2 is very well regarded)
