I'm looking into a wide angle converter for my GY HM 100U camera and was a bit disturbed by a reviewer who said he bought one from 16:9 (?) that didn't fit the camera even though it was made specially for it. As I live in South Africa, and usually order from the US, I can't take chances on having to send back my orders. Has anybody got any, proven, workable, preferably affordable, ideas? I found one post that mentioned a Sun Pak for $50 - sounds unbelievable. Does that actually work?
