A quick side by side test of the new iPhone 5s housed in a Hitcase and the GoPro 3 Black Edition. I'll be honest, I may have wet my pants from fear, when taking a brand new iPhone out into the water.
Both cameras were mounted together on a GoPole reach, set to record 120fps and the GoPro framing set to wide.
I did a very quick colour correct in the first segment, as the iPhone appeared to slightly over expose and the GoPro under expose. I'll do another test soon in better light.
