I hope an expert can help me create a solution for this problem:
I purchased a mini wireless color video camera to install on a radio-controlled helicopter. The camera is about as big as a quarter in size. I subsequently purchased a wide-angle lens to replace the lens on this camera. I unscrewed the original pinhole lens and, to my pleasant surprise, the threads on the wide-angle lens matched and it screwed on nicely. However, I discovered that in order to focus, I had to unscrew the wide-angle lens to the point where it hardly has any threads holding it on. Is there such a thing as a lens length extender? Or should I maybe just use some electical tape to secure it? Any ideas?
