Have you tried using a flash with this rig. Perfect synchronization would suggest "yes", at least with a dumb flash. But what about with a TTL flash? 2 TTL flashes?
A soft bokeh is easy to achieve using a large aperture in order to obtain a shallow depth of field, just as it is done in 2D photography

On the other hand some people have tried to prove a bad synchronization of the current Sony cameras pointed out the synchronization flaws of some photos of Venice (wrongly since they were made 8 years ago with Nex-5 rig, using finger sync !) believing, wrongly, that they were made with the current Sony Alpha cams:

Those same people have not tried to discredit the Sony Alpha sync by pointing to the series about the acrobats girls and not pointing to the other series about “modern” girls street dancers:

Both facts proves that these people, at least visually, also accept (implicitly and indirectly) the perfect synchronization of the current Sony Alpha cams, through their MultiTerminal port.
Now all of us, 3D lovers, can have equipments with the same technological level that the 2D photographers. I think really a new era begins in 3D photography: the Sony MultiTerminal era.
Everyone will be welcome to the 3D Sony club :) 3 dozens of extraordinarily good 3D rigs, (with the same technological level as the best current 2D cameras :) . Every 3d photo fan can select your own 3D Sony rig:
A7, A7R, A7S (I, II, III) A9
A5100, A6000, A6300, A6500
NEX-3N, A5000
A3000, A3500/
A58, A68, A77II, A99II
RX1R II
RX10 II , III, IV
RX100 II , III, IV, V, VI
HX300, HX350, HX400
HX50, HX60, HX80, HX50, HX90, WX500 (with external trigger?)
Certainly it is a new world, That is a big game-changer.
