I suspect you are talking about the equivalent of the Vivitar 2xmacro convertor. I have this convertor and it is A) a very good convertor in its own right. B) Even better because it has the helicoid which makes it an exceptional cose-up tool. I paid about $100 Cdn. --$60U.S. for it. I don't think a Panagor model would sell for that high a price, but I suspect it is the same thing. I could be wrong... Vic
