I have this great little cam HDG GW77, it works very well but I've noticed sometimes (in the rain) or when there's a temp difference (in/out water) the lens gets a bit misty on the INSIDE. How can I stop this? I've tried leaving the cam open in the sunshine for an hour or so just in case there was any dampness inside. It's not always like it, just now and again. Any ideas?
Mike.
