V860N Flash Power Issues

I just bought a V860N flash.
There is no difference between 1/1 and 1/2 if the power is set by the cactus V6.
I tested with the flash in manual mode and the difference is clear. It seems that cactus triggers the V860N at full power in both power settings 1/1 and 1/2.


  • Hello @SBP

    We tested the V860N flash on V6 running on Firmware version 1.1.008 and power outputs are functioning well.

    Would you happen to have a light meter or doing a few comparisons between 1/1, 1/2, 1/4, 1/16 etc?

    Many thanks!

    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".

    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. So for all other systems (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!

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