Does anyone have experience with a remote flash trigger that works with the sigma fp/fp L via the HU-11? I realise the fp has a rather slow flash sync but I am curious if there's a way to use the camera in a studio set-up with 2 or 3 off-camera flashes. I tried a godox x1 tt-o to trigger a godox tt685ii speedlight but I was unable to get it to work on the fp L.
Thanks
Apparently you used a version of that Godox trigger that is designed for Olympus and Panasonic cameras, according to this:

I believe you need to use one that is compatible with a Canon camera. I believe Sigma has always made their flash shoes Canon compatible (probably because Canon was/is the most popular brand of cameras, so they figured there would always be flashes and triggers that would be compatible with them).
Good luck figuring it out.
