G9 with Metabones T Speedbooster XL 0.64X problem

SOLVED!!! The culprit proved to be an almost imperceptible burr on the base-plate of the SB adapter, at the edge of the "pin-locating" hole which mates to the lens pin on the camera body.

Evidently, as the adapter was rotated into place, the burr prevented the pin from expanding into the hole in the adapter and thus registering as a release button press.

I taped up the critical bits of the adapter, then used a Dremel Tool to grind off the burr, and slightly widen the hole also to more closely match those on my native lenses.

Thorough cleaning of adapter and pins, then success - MB SB XL0.64X (v3.31) running on G9 (v1.3).

Et Voila!!!

Thank you all for your thoughts and suggestions.

Glad that you worked it out Mark - now enjoy ...

Now the way is clear for an Ultra 0.64x at some future stage when my lens enthusiasm gets control of my common sense

I do have a lot of EF lenses and I do use them on M4/3 bodies and the Metabones adapters are expensive (but very good). As I sometimes need more than one adapter at the same time I added Viltrox to my adapter count.  They do work well and also for many lenses but their compatibility id not as wide as that of Metabones - Viltrox specifically advised me that their focal reduction adapters don’t work on lenses f1.2 and faster - which I know by experience is true.

Having both Metabones and Viltrox means that I can mix and match compatibilities when put to the test.
