HARD!!!!!
The Novo Camera ($300/day, $900/week) is designed to overcome this limitation by repurposing a GoPro Hero3 in a tiny, lightweight aluminum housing that can accept C-Mount lenses and adding new exposure control capabilities, opening up a slew of new artistic possibilities. Not to worry though — it still offers most of the key features of the Hero3, including the LCD touch screen, WiFi connectivity, and up to 4K video recording.
