I check out this forum daily and have learned very much from you guys in the last year... One of the things I learned is that an HD camera is very expensive. Apparently, that is one of the reasons my favorite show, "Survivor" allegedly will never be fimed in HD. (Although I still can't understand how a consistently rated top-ten show could not film in HD due to cost.) Now I hear that the cameras are very bulky and cannot be used as helmet cams during the Winter Olympics. Does anyone have a definitive answer or possibly some photos to explain/illustrate what an HD camera actually looks like, how much it costs, etc.?
