Strobes out of sync when triggered optically
Mar 2, 2013

Got a set of three cheap studio strobes (Neewer c300). They came with a single rf trigger, and they can act as optical slaves.

They work just fine when using the radio trigger, the secondary strobe fires from the primarie's flash, and contributes to the shot normally. However when i use the camera's own flash as master, the strobe fires, but contributes nothing to the shot, because it is out of sync.

Confused by this to say the least. It sees the camera flash, and fires, but the shutter is closed by then. Yet when it triggers off its companion flash (which syncs via rf) it syncs into the shot.

I have a nissin speedlight, and can get it to fire off camera via the ittl cmd mode fine, but when i power it off, then turn the studio strobe on (ie change nothing in the camera settings), the strobe fires but not in sync.

Suggestions?
