Next out, the iPhone's 12 MP peeper!

This year's camera offers a substantial spec bump from the 6, including the first resolution increase since the iPhone 4s.

50% more focus pixels means faster, more accurate autofocus without a drop in quality.

The new iSight camera also brings the iPhone into the arena of 4K video recording, which has previously been dominated by Android phones.

Increased pixel density often comes at the cost of a decrease in individual pixel quality, due to crosstalk from competing photodiodes, but this new iSight camera includes some cool technologies that mitigate that issue.
