Apple has officially announced the iPhone 6 - the eighth generation of iPhone - at a special event in Cupertino.

In fact it's just 6.9mm thin, making it one of the thinnest smartphones of the market, and rumors about a protruding rear camera lens are also true.

It's slightly heavier than the 5S at 129g, while the body measures 138.1mm x 67mm.

The iPhone 6 has a 4.7-inch LED back-lit display with a 1334 x 750 resolution - it's Apple's new "Retina HD" offering. That means you get a pixel density of 326ppi - the same as the iPhone 5S.

It also pales in comparison to the iPhone 6 Plus, with a full HD, 1920 x 1080 5.5-inch screen with a 401ppi display.

Apple has stuck with the 8MP rear camera on the iPhone 6, but it's not the same as the one you'll find on the iPhone 5S.

A new wide angle iSight lens, true tone flash, f/2.2 aperture, greater noise reduction and a 2 x faster autofocus provide even better images.

There's also a new Apple-design image signal processor built into the A8 chip to improve the way the iPhone 6 handles images.
