The AK-TTL wireless radio trigger will offer full TTL, high speed sync, ratio lighting control and a 110 metre operating range. Coming soon!

Aokatec AK-TTL

We’ve seen wireless radio flash triggers with TTL support from PocketWizard, Pixel and Phottix. Now there’s another contender.

Aokatec AK-TTL

Aokatec are a Chinese company who have announced the AK-TTL Radio Wireless TTL flash trigger, which will be available for Canon, Nikon, Sony and Pentax cameras and speedlights. Nobody else offers a Pentax P-TTL trigger yet, and only Pixel offer a Sony trigger, so this is one to watch.

The AK-TTL will have the following features:

  • Full wireless TTL
  • High speed sync (HSS) up to 1/8000 second
  • Ratio lighting control of multiple remote flashes
  • Operating range up to 110 metres
  • 16 channels

So far we only have the above picture (and below video) giving us a glimpse at the transmitter. More details and images are coming soon. Though release was first slated to be the end of February, the Aokatec Team say there is “some delay” in development.

Stay tuned for updates.

  • Just curious – do you have the chance to test them? In the meantime it seems they are available. E-TTL sounds like a big advantage, but according to the manual the E-TTL signal is neither acquired by the transmitter via hotshoe (the transmitter instead recognizes E-TTL via IR signal, which will limit compatibility to Canon bodies with build-in or external ST-E2 or Speedlites with master ability (90EX, 550EX – 600EX)), nor transmitted to the flash via hotshoe (radio signals are converted back to IR instead). What’s the deal here? Black-taping the IR sensors to the master/slave IR to prevent daylight interference? After all and even considering taping for daylight the IR to radio to IR looks like a huge bottle neck just from reading …
