Get a Thunder Lightning in pictures using the V6 + cable release

edited August 2015 in V6 Questions

I just received my 2 cactus V6 and a Canon 600EX-RT.

While unboxing and testing I had all configured and the flash on the tripod. I accidentally emit a flash with a 1000 Lumen led torch to the V6 optical sensor with the "Optical Slave" function ON on "S2 Main Flash" mode. And that's triggered the Flash.

I was wondering if anyhow it could be possible to use both functions with a trigger release cable to trigger a shot from a Thunder Lightning strike.


  • Hello @Miro

    We haven't tried that before it may actually work!

    If the lightning is not bright enough, what you could do is switch on your portable flash's optical slave, so once the flash is triggered by the lightning, it fire a flash directly into the V6's optical sensor, and then triggering camera's shutter.

    FYI the otpical sensor on the V6 was designed for flash profile learning so it has a lower sensitivity.

    Have a try and let us know how it goes!

    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.
