Hi Martijn,
Wow! A cadaver Canon 1.4X tele-extender!
I can think of a number of additional experiments:
1) Reverse the optical elements so that the image circle is *SMALLER*
Why make a 0.7X vignetter? To use wide angle lenses on the EOS D30
CMOS sensor, of course! :-) It this works, this one would *REALLY*
popular.
2) Try to fit a *tiny* switch to enable/disable the extra 3 pins.
Maybe a reed switch activated by an external magnet?
Cheers
Julian Loke
