I have been testing the V6IIs with the Nissin i60as in the last few days. All functions are working perfectly, except the V6IIs will not trigger the i60as in M mode. The V6IIs is mounted on the A7II multishoe and the i60as is mounted on top of the V6IIs. If I mount the i60as directly on the camera multishoe, The M mode on the i60as works fine.
I tried the V6IIs in both the TTL pass-through mode and non-TTL pass-through mode. I tried both the Sony profile and the AUTO Sony profile. None of them works in M mode. Please advise.
M mode is set on the flash.
Thank you for the clarification. I guess this is one area the V6IIs could be improved, by having the TTL pass-through functions exactly as if the flash is mounted directly on the camera's MIS. Sometimes I want to control the power of the flash attached to the on-camera V6IIs manually, but it looks like I will need to use FEL to sort of compensate for the lack of this capability.
