Re: 50mm Macro, EX25 and EC14

It's too late on in the evening to dig the kit out now, but I don't think you can even use manual focus, as the 50mm is focus by wire, and thus needs a camera supplied power source. An SWD lens should work in MF as there is a direct coupling of the focus ring.
As I understand it, the only way to use extender and extension, on a fly by wire lens, is to butcher the ex-25 to bypass the chip with some ribbon cable, such that the camera doesn't realise its presence
