Profoto and XF 100MP REAR sync mode

Postby greggulbransen » Tue Dec 20, 2016 2:21 am

Does anyone have an answer as to why my XF 100MP camera will not sync with the Profoto strobes while in REAR sync mode? When I shoot the flashes go off but way after the exposure is done. When I dial the camera to FRONT sync all works fine but honestly it should work both ways? I had assumed it would be the same as with my DSLR cameras but I must be doing something incorrectly.
My dealer has no answer.
Thank you in advance-
Greg Gulbransen.

The flash analysis tool in the XF should help you figure out when it is flashing and also help you trim it in perfectly:
