Just thought I'd pass on this silly little suggestion. I've had my Opia2 for over a year now and it works great, but I haven't checked the videos or SD card in a long, long time. So today I decided to look at a few videos and see how everything was working. The video quality just didn't seem as good as what I recalled seeing when the camera was new. A little too blurry and dark for my liking. As I was checking things out I noticed that the CPL lens looked dirty, similar to what the inside of your car windshield looks like when it gets a smeary film on it. So I took it off and cleaned the lens. Presto ... video quality looked as good again as the day I first installed the camera.
