the gopro isn't necessarily fixed at 170 degrees.
wide FOV - 170
medium FOV - 127
narrow FOV - 90
fixed focus isn't always a disadvantage. footage taken with cameras which are constantly searching for focus is disappointing.
i'm not saying that a gopro is the right answer, just that they are more versatile than many people think and unfortunately, most of the underwater gopro footage that appears on youtube is very poor quality due to the users abilities or mounting technique. pole- or even worse, head-mounted cameras cannot be compared to tray-mounted setups with lights.
