I used to do all my videoing with a still camera in video mode, held in my hand. I now am the proud owner of a GoPro Hero 2
, which has been amazing. There was a bit of a learning curve as I figured out the beeps and modes, but now I have it down and its been a blast.
I do have to say the "waterproof" case has not been so, so not sure that I would take it swimming as they advertise.. but the camera hasn't had any issues with the rain or dense fog, other than condensation forming inside the case and making the picture spotty (aggravating, but fixed with wiping out the case with a towel).
It deals with the rocking/shaking motion of riding well, though I suspect anything would be better than my hand-held camera.
It does well with the light to dark transitions of sun to shade nicely too.
