A camera is a distraction from the the very beginning to the very end of any skydive.
Items may missed during a gear check because of a battery check on your camera. A lift web might be twisted but the jumper is paying more attention to the camera mount while gearing up. A handle is floating but the jumper is double checking that his go-pro is turned on on his way to the door. Get the idea??? It gets worse the further along in the skydive you go.
A camera flyer must have sufficient experience to not only fly by second nature, but skydive by second nature. That comes with lots of experience!! 200 jumps is a minimum recommendation. That's a reasonable number of jumps to warrant an evaluation of one's ability to safely carry a camera on a skydive in my opinion.
