Hello Everyone... I have a HDR-SD12 which I have really enjoyed. I have a screw on WA lens that won't screw onto the front of the camera. There is a retractable spring loaded pin at the screw on position that is what I think is keeping it from screwing in fully. When I push in the pin the Flash (lightening bolt image/CHG light turns off and a line through a Lightening Bolt image appears on the screen. I know this is so that the will not fire when using accessory lenses. No matter who I try I cannot get the lens to screw on. It has been years since I have used the lens and I remember it working before. What am I forgetting to do? Thanks!
