Originally posted by zazism_rx I experienced this with the cactus triggers as well.
As long as the shutter speed doesn't exceed the sync-speed, the Cactus trigger will work even with manual lenses.
If you are using a V6II, you may have to set the "FLASH SYSTEM" to "OTHERS" but it should work.
Originally posted by stevebrot The behavior is reproduced! BTW, I consider this to be a bug.
The fact that the Xpro-P won't play with manual lenses is not a bug, but the absence of a feature.
The Godox X1T trigger still supported a "single pin" firing mode (but is not a good choice in practically every other way). This would work with manual lenses as well.
For some reason, the Xpro triggers do not support that feature.
I'm sure Godox could add it, but the absence of the feature does not technically constitute a bug.
