V6 II Compatibility with Fujifilm X-Pro2 new Firmware Version 2.0


Fujifilm has just released firmware Version 2.0 for X-Pro2 and it seem that there are some compatibility issues. Hope this is the same compatibility issue with X-T2.

Is there an official firmware update for X-T2 compatibility to test?

Thank you


  • Hi CG,

    Yes, you will need to wait for the next firmware release.
    The current firmware version, 1.1.004 does not support X-T2 and other newly release Fujifilm camera firmwares (to work with their upcoming EF-X500).

    There is a beta firmware on the V6 II that we are testing, if you are intersted to try, hop over to: http://www.cactus-image.com/community/discussion/1005/fujifilm-x-t2-compatibility-with-cactus-v6-ii-to-support-hss/p1

    And send an email to info@cactus-image.com.

    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).
