I picked up a pair of these over the weekend, and use them with my new Sony a6000 just fine.
I was curious if anyone knew of compatibility with my old 350d, which my son has been using now. I thought I recalled years ago people being concerned with flash trigger voltages and even though its an older body - don't want to needlessly fry it.
In the meantime, I guess if my son wants to use manual off camera flash, I'll just have him set the Yongnuos' to optical slave and trigger it via pop-up flash or the TTL speedlite I've got for that camera.
Thanks
