With the caveat that the video has been produced by the Windows Phone team, there's a short but entertaining look at 'The Rig' that was constructed to compare the Nokia Lumia 928, the iPhone 5, and the Samsung Galaxy S4.

The rig holds five cameras, and custom software has been used to ensure that a single shutter release happens at the same moment on all the cameras in the rig. Each handset is also left in 'automatic' mode with the flash set to 'off'

From the YouTube description:
