Both front and rear cameras on Z1 have better specs. iPhone has better software optimisation, not hardware. I do not agree that iPhone camera is always better, some shots are better on Z1 (of course, superior mode must be turned on for 8 mpx stills). Also Z1 records rich stereo sound as opposed to pretty flat sound on the iPhone. Plus, Z1 is IP58 certified. Plus it has expendable memory and a lot more freedom because of Android OS. Conclusion: not everything is better on the iPhone.
