AF Assist light on the flash

In the same manner that the new V6 II trigger/receivers can emit an AF assist light, can the receiving units be set up to trigger the flash to emit the AF assist light?
Most flashes have a powerful AF assist light built into them and it would be nice if that could be taken advantage of.

The V6 II already have functionality to adjust zoom on the flash. Why not AF assist light as well?
This would likey be just a software change.



  • At the moment the AF light on the V6 II will come on.

    But let me check with R&D and see if this is possible.

    On a side note, the typical nice pattern from the flash won't be appreciated as much by the camera - unless you place your off-camera flash somewhat right above your camera so that it's on the same axis, otherwise the AF light pattern won't line up with your cross type AF points. Nonetheless more light should technically be better for AF.

    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", "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 and OLY.A.001.  No schedule has been released yet. 

    Cactus RF60X / RF60 Firmware versions A01 and A02 currently ONLY works with PEN.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.

    Cactus RF60 is now an off-camera TTL flash with firmware version 205 or later!

    Metz M400 (for Fujifilm) is now supported on the Cactus V6 II (HSS and TTL).

  • Thanks for looking into this Antonio.

    Good observation on the fact that the flash AF assist may need to be aligned with the camera axis, but like you said, the more light the better.
    Besides, since the flash is sitting on top of the V6 trigger, both AF Assist lights point in the same direction, and both would be just as useful.
