Peter, I just did not know that 2x applies not only to focal length but to other parameters as well. I actually thought that the light loss is __totally__ different parameter that varies from converter to converter.
That's because the only converter I have, that being Panagor Macro Converter, has different light loss depending on chosen magnification factor...

A 2x TC will cost you at least two full stops. (More depending on the TC but that's another problem).

I am over 30, but I think I had my "ignorance moment" when I read your questions...Does the 2x make the lens a 400 from a 200 AND the f stop from f4 to f 8????
I think that if converter looses half the light it means it is one stop which I suppose is f5.6 from f4 and not f8.
I wonder whether I have just irreparably damaged my reputation in the club... <VBG>
