Timing issues - Olympus OM-D EM-1 V6 and Nissin i40 TTL pass-through

After some pass-through TTL issues with a Nissin i40 on the V6 on an Olympus OM-D EM-1 (which seem to be down to the power-on order - I had to go bottom (camera) first) I am having some timing issues.

This is a rare setup which I would only use in rare occasions (e.g. wedding photography dancing) but was part of my testing.

Camera is an Olympus OM-D EM-1 - V6 on the hot shoe and a Nissin i40 in TTL pass-through mode (and in TTL) mode

Two remote groups - A is an Elinchrom Quadra triggered by a V6 in receiver mode and cable connected

B is an RF60 

A and B flashes are in manual mode obviously and are used as accent/rim lights

The onboard TTL flash is providing the key light.

Both channels are flashing - but the A channel is not appearing in the camera frame.

Anyone any ideas how to fix - clearly some timing issue.




  • Hello Alan,

    Thank you for your inquiry.

    Have you tried shooting:
    1. Without mounting the Nissin flash and turning TTL PASSTHROUGH off? 
    2. At a slightly lower shutter speed? help with synchronizing with the Elinchrom?
    3. Only with the Elinchrom setup?
