SB-910 apperture and iso, focal lenth

I have a Nikon Flahs SB-910 and D7100. When I
change the apperture and iso,
 focal lenthon the camera, Does it goes through the
wireless of the V6 or V6 ii?




  • Wireless, no.

    The V6 / V6 II both do not transmit TTL signal wirelessly.

    They are both a manuall flash trigger so you have to set the power and zoom setting manually.

    The V6 II just happens to be a manual flash trigger that supports:
    1. wireless power control
    2. wireless zoom control
    3. wireless HSS / FP mode

    To help us better help you, always state the exact firmware version installed on your Cactus device(s), such as: "1.1.013", "FUJ.1.002", "NIK.A.001", "v.103".

    For the time being, Cactus V6 (MK1) running on firmware version 2.1.001 can be triggered by a V6 II (MK2) running on Multi-brand HSS firmware (e.g. 1.1.013) and not by X-TTL firmware versions:  PEN.A.001 NIK.A.001 OLY.A.001.  No schedule has been released yet for an "A" version firmware on the V6 (MK1). 

    Cactus RF60X / RF60 Firmware versions A04 and A03 currently ONLY works with PEN.A.001 NIK.A.001 and OLY.A.001.  Other "A" version of X-TTL firmware will be released soon. For both Multi-brand HSS and X-TTL firmware versions (FUJ, SIG, SON), install firmware version 103 / 205 on your RF60X / RF60.
