Phottix Odin, Mitros+ overexposure

If you’re experiencing over exposures in ETTL mode when using the Phottix Odin TCU and Mitros and or Mitros+ flashes OFF CAMERA, join the club!!! Here’s how I fixed it. But first a little more info.

I updated the firmware on the Odin, here’s the page to get the firmware:

Phottix Odin for Canon firmware update

Then if you’ll notice the lighter font section near the bottom “Update 08/8/13:” I followed that. Voila! over exposures when off camera (3 different flashes) in ETTL mode. Manual is fine, on camera is fine.

So after months, more like a year of just using my flashes in Manual mode and finding it a paint to keep pushing the buttons on the Odin TCU, I decided to try and fix my odin’s. Also I went to a Godox sales pitch thing regarding their new line of strobist gear…The gear and tech put me in the mindset where I was at when I contemplated the change from Canon to Phottix. Cost vs Tech. Phottix won…It seems Godox (to me) is getting there in terms of quality. They are cheaper than Phottix in price and the seems more versatile.  So I’m thinking about it because if I can get a fair price for my phottix gear, I can get a bigger (more stuff) Godox system. But then it’s such a hassle and I do so love my Phottix gear.

Anyways, as written on the Phottix page, it seems you need to turn the 1d to off…That didn’t work for me. However, I was thinking…ya maybe its a language barrier or I just interpreted it wrong, so I switched mine on. VOILA!!! IT WORKS!!! HAHAHA…don’t know why, or how but at this point, I don’t care cuz it’s working, YAY! If you’re pretty much in the same boat as I was, give it try, it’s just a setting, you can always change it back.

Good Luck! Hope this helps you!


After the above fix, I was playing around some more and found out that my both my Mitros+ flashes when used on camera in Odin Tx mode would grossly over expose. What?!?! So first thing I did was check firmware, mine was outdated so I updated. That is the fix that worked for me. A firmware upgrade to v 2.12. You can get the downloads you need as well as instructions on the Phottix website.

NOTE: Apparently, the updater software is OS specific (yes even different versions of Windows). I’ve read about differing named Windows OS not working ie WinXP and WinVista but for me I couldn’t get the updater to update the second Mitros+ on my Win10 hybrid laptop (the type where you can remove the keyboard). I kept getting the “No FDS Device” error.

My fix was to use my regular laptop running Win10 to update the firmware. The process was smooth as butter for both my Mitro+ and Mitros.
