Lightbulb Re: What is the extra connection pin on MC14 for?

I think I've finally solved my question. Since the MC14 doesn't have any firmware in it it then it has to have something for the lens (& body) to know it is in use & also which TC is in use. The 40-150 Pro lens has two connection pads & the MC14 connects with only one of them, leaving two more pin combinations (the other contact point or both) so the coming MC17 & MC20 will be catered for.

As much as we thought it was to do with other TC but I hadn't realised the MC14 doesn't have firmware like the EC14 & EC20 does though (until I checked last night with new updates being available) & why it is necessary to have another means to identify that the MC14 TC is being used with the lens (40-150 & 300).

Just updated the 300 FW with the MC14 attached and it worked as if it was naked.
