> I couldn't find the female version cable so I just bought two male cables
I looked for a female Sony multi-terminal cable (Female-S2, replacement for the RM-SPR1) and I only found it in China, but avaiable through Amazon Spain:
This weekend these two cables (male and female) arrived. I do not know if the synchronization works well at all the Sony cameras with multi-terminal port . I only can confirm that with 3 Alpha models : A5100, A6000 and also A7S (until ISO 400.000!).
In any case, each 3D photo lover can make the appropriate checks, only under their own risk.
A new era in 3D photography, at least for me (excited and happy), now begins: The Sony Multi-terminal Era.
Also many people have reported that good synchronization is possible using the Canon G9 and M3 (also the M10 ?) cams, with the StereoDataMaker software (version 2.2):
