Problems with AOI trigger and backscatter MF-1

Hello everyone,

A colleague of mine is having problems with her Backscatter Mini Flash-1 and her new AOI housing for the Sony A7CII.

I know that the MF-1 can be quite finicky when it comes to fiber optics, and problems are often related to the cable. I experienced this myself with my MF-1 and the manual Nauticam Sony trigger. However, I eventually found two cables with which the MF-1 almost always worked.

My colleague is now having nothing but trouble with her new AOI housing for the Sony A7CII and the trigger. She has tried countless different fiber optic cables. Sometimes the MF-1 seems to work, and other times it doesn't. The INON flashes she still has work without any problems with all cables. The trigger is always in manual mode (WL ON).

Could it be that the older MF-1 flashes are causing even more problems with the newer triggers? It worked perfectly with a TRT trigger I had previously used in a different enclosure.

Or does anyone else have any ideas? I'm meeting with her again tomorrow and will take another look. And I think it would be best if she also asked Backscatter directly. But collective wisdom is usually even more helpful!

Thanks in advance for any feedback,

Tino
