Eh, the Canon and Nikon versions i don't think the TTL will work right? It's different companies..and besides the Sony flash will not fit the Canon or Nikon mount properly also...the pins don't align.
The only way i managed to get it to fire off was to cut away the front part of the trigger so the flash can be inserted more than normal just so the firing pin can be aligned..
i also don't think a Canon trigger will work because i actually cut a Phottix Canon trigger and aligned the pins but it won't fire either..so basically i destroyed a good set of Phottix trigger
I bought a cheap Chromage universal trigger and that one worked.
Haha... I am using my Canon 430ex ii on my A7. Works perfectly fine, manual mode only.
