I have been using my father in laws Samsung mini dv camcorder over a few occasions over the years. I borrowed it just before Christmas intending to video the kids. When i first tried to use the camera there was a dew warning (the book recommended ejecting the tape and keeping the camera in a warm place) this i did and all seemed fine.When filming my sons assembly at school the camera didnt seem to focus properly. I simply presumed this was due to some moisture condensing on the inside of lense. So afterwards i returned the camera to a warm room and also put large bags of silica gel in the case with it, this did not seem to help. Today i have had another look and have found that when the night vision mode is turned on the picture is in perfect foucus, both in auto and manual focus modes. When Night vision is off the picture is blurred again even on manual you cant get it to focus. Has any one any ideas.
