Firmware Release Notes?

I just received a Cactus V6 and two Cactus RF60 flashes, and updated the firmware in all three devices.

I noticed the latest version of the V6 firmware was dated December 8th, but there was no announcement of a new firmware release on the home page or in the forum, and there are no release notes.

Is it safe to use this version? What was changed?


  • Hey guys, it's safe.

    The link to the Firmware Release Notes should always be this:

    Bug fixes:
    Fixed the inconsistentpower output of SB-600, SB-900 and SB-910 profiles after switching off and on the V6 again.

    Fixed the triggering issue with the profile of Nissin Di-866 for Canon. User interface improvements:

    Standardized the LED signal length on RX whether it is triggered from the TX in group sequence mode or not.

    and more... Please see the PDF link above.

    To help us better help you, always state the exact firmware version installed on your Cactus device(s), such as: "1.1.012", "FUJ.1.002", "v1.02".

    Cactus RF60 is now an off-camera TTL flash with firmware v2.05!

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