Petition – Radio Based Flash for Micro Four Thirds

A group of Micro Four Thirds Olympus and Panasonic mirrorless camera enthusiasts have started a Facebook petition page entitled – We Want Radio Flash for Micro Four Thirds.

Thomas Geist, initiator of the petition, contacted Flash Havoc asking for support to help spread the word and convey the message on to the 3rd party manufacturers.

We just started a petition page on facebook to make the 3rd party flash manufacturers aware of the need for an advanced radio flash system for Olympus and Panasonic Micro Four Thirds cameras.

Nikon and Canon users had the luxury of such systems for years and the latest releases by the likes of Phottix and YongNuo bring the most desirable configuration at affordable prices: advanced flash, radio master and slave all in one.

The latest mirrorless offerings from Olympus and Panasonic are hugely popular and we would love to see the same flash offerings for these systems.

Although I really don’t know if there are currently any dedicated Micro Four Thirds flash or trigger systems in development, the need for radio triggers to be universal and compatible with single firing pin and other mirrorless cameras is one the comes up a lot now, and manufactures are certainly becoming very aware of this. This is because many people (and professionals) are now using Canon and/or Nikon DSLRs as well other brand mirrorless cameras at the same time.

YongNuo have already confirmed the coming YN-560TX transmitter (which will provide remote manual power control for the YN-560 III flash unit with built in radio receiver) will be compatible with single firing pin and non Canon-Nikon cameras (provided they have the regular non Sony hotshoe). So the remote manual YongNuo system may be one good solution if TTL or HSS are not such a priority. If you can’t wait for the YN-560TX, the (now overdue) RF-603 II will be universally compatible as well.

YN-560 TX

Even many more advanced TTL systems like the coming YN-622TX could theoretically still operate in remote manual power setting on non Canon-Nikon and single firing pin cameras. That is provided the manufacturers see this as a priority and make allowances for it. So this extended compatibility is also something we will be taking a lot more consideration to as well with coming TTL triggers and Radio based flash units.


For radio based TTL and HSS capability there is currently only one solution on offer, the Aokatec AK-TTL.

And even the AK-TTL are only compatible with Olympus cameras at this stage, and only the cameras which currently have IR based wireless flash systems already built in.

This is because the AK-TTL are a a simple optic to radio converter, working on a similar principle to the better know Radiopopper PX (which are not Olympus compatible). The AK-TTL are arguably more cumbersome than most regular radio triggers to connect to the flash units, using elastic bands etc, as seen on the Aokatec website here. But they do at least provide one current solution most owners have reported to be fairly reliable.

The Aokatec AK-TTL are available for around $110 a pair on Amazon.


If you would like to see more advanced Radio Flash systems for Olympus and Panasonic Micro Four Thirds please head on over to the Facebook page and show your support on, so the manufactures really have to start taking notice.

And if you haven’t already, please join the Havoc on Facebook too!

    Liked their facebook page already. But I’d be satisfied with a simple 560TX system on my Olympus.

      I’d want the 560TX built into a smallish (YN-500) flash with a non-TTL “auto” exposure mode. This’d work on any camera with a hotshoe. As an event shooter, I’ve gotta have on-camera flash with autoexposure, so a standalone 560TX with no pass-through hotshoe is a non-starter for me.

    Dear MFT shooters

    Stop whining and harden up. Seriously, every other freaking flash platform has more TTL flashes than we do, and you don’t see us complaining!

    Also, not a single mention of our new flash on here.. not one little peep!!

    I don’t understand the whining.

    If you really want radio triggers, you’ll use them in manual mode 98% of the time anyway. You can just get the once from Nikon, and be fine with them… I’m using my YN-622N on my GX1 all the time…
