C.H.,
I'm very curious to learn how you managed to combine the Tamron 2X SP
with the 100/2 Zuiko. As far as I know, because of its front end
mechanical configuration, the Tamron 2X SP converter can only be
physically coupled to Adaptall-2 lenses -- bare, without the mount
ring. In other words, the only Tamron 2X SP converters I have ever
seen must be inserted between the Tamron lens and the Adaptall-2 mount
ring. (Btw, same goes for the Tamron 1.4X 140F converters.)
Cheers,
