Just experienced that obviously Canon\'s 1.4x teleconverter II for EF can not simply be attached to an EF/FD adapter (without glass element). The EF/FD adapter is used to connect with a Canon FD auto macro bellow. Everything works perfectly fine if the bellow plus adapter is directly connected to the camera. But if the 1.4x teleconverter is located in between, an error message shows up after the shutter release button is pressed stating \"Error 01\" and the picture is not taken.
It looks like the extender asks for an attached lens or connection which directly uses the contacts of the extender (this is used to control the lens aperture). The EF/FD adapter does obviously not use any of those contacts.
Did anybody else observe a similar problem? Is there a way to use the Canon 1.4x teleconverter in such described combination?
