I bought a kit three flash studio GODOX sk400ii with the trigger XT-16.
Sometimes when I'm almost at the maximum sync speed of my camera, the sync is not perfect (I have a black band at the bottom of the image)
I use a canon 6D and the maximum sync speed is 1/180.
But at 1/180 it does not work with the XT-16 (black band). at 1/160 it works almost all the time but sometimes there are black bands. at 1/125 I never had a problem.
I did tests with a canon 600d and it works all the time at 1/160, because the maximum synchronization speed of this model is 1/200.
I conclude that the XT16, or the receiver built into the SK400ii is not always very accurate and this is visible when approaching the maximum speed of sync cameras.
Have you ever seen this problem?
Do you have any ideas to solve the problem?
Sorry for my bad English, I speak French.
Thank you for your help,
