Will not work with Radiopoppers™ triggers with Sony cable adapter, and won’t work well at all with Sony live-view mode.
Doesn’t function correctly (and is not usable) in Sony’s live view mode; seems to default to full power blast for all shots.  Tested on Sony A580, but may work properly with other brands.  Recharge times are too long at higher power settings.  This flash is the same one Fuji sells for the X100 camera at a much higher cost, only the hotshoe style is different.
Good for
Fully automatic use with Sony optical viewfinder camera.
Not good for
People wanting to use it in Sony live-view mode, wireless optical use, Radiopoppers™ use, or HSS.
Not for Sony users.
