It’s been a little over a year now since Cactus first announced their cross-platform X-TTL system. It came with a flurry of firmware updates to let you get HSS & TTL compatibility across multiple brands of camera and flash. These updates added support for Fuji, Sony, Sigma, Nikon, Olympus, Panasonic and Pentax. But you’ll note that there’s a big name missing from that list.
Cactus’ new firmware update adds that name, by offering support for Canon wireless flash. The new firmware for the Cactus V6 II transceiver allows it to wirelessly communicate TTL information between a Canon or Cactus flash and a Canon camera.
So with the X-TTL system now complete, here is the full compatibility chart covering all of the different camera & flash brands it supports, and to what level of capability.
It’s been interesting to watch brands like Cactus and Godox both developing cross-platform systems. To take advanced features like high speed sync & TTL from one brand’s flash protocol and then convert it into a different brand’s protocol is pretty amazing. It’s made the lives of certain camera brand shooters a whole lot easier by opening up many more flash options, not to mention those who regularly shoot multiple brands of camera.
It doesn’t mention anything in the press release about this but I’m guessing this compatibility will also come with the upcoming RQ250 portable strobe. The RQ250 is expected to come out sometime in September, but a price still hasn’t been announced. Given today’s earlier announcement from Godox for the AD400Pro, I’m curious to see how everything will play out in the low power portable strobe world over the next few months.
To find out more about the Cactus X-TTL system, head on over to their X-TTL microsite, and to download the new firmware, check the Cactus downloads page.

Sorry I’ve had problems with downloading firmware from sources other. I now always use Nikons site
The firmware is for the Cactus triggers, not the camera so you can’t download this from Nikon.
What you do is upgrade the firmware of the trigger to the brand you shoot by using the software supplied by Cactus.
For you that would be the Nikon XTTL firmware, for me Sigma as that’s who I shoot.
