I shot a wedding last Friday and had a few misfires with my set up, enough to make it annoying and want to really troubleshoot it. Mostly the misfires occurred outdoors. I'll get into my set up and what was going on in more detail;
- Two cameras (K-1 and KP) each equipped with a V6ii in Tx mode.
- 2x RF60x units
- Light stands and diffuser umbrellas with the RF60x's onboard.
- Ikea LADDA rechargable batteries in all Cactus equipment.
What was happening, for example, formal shots post ceremony outdoors. Using HSS and having the umbrellas/flashes camera left and camera right so I could assist in some fill light for the group shots. Sometimes one flash fired, sometimes both wouldn't. Sometimes I would try 7-8x in a row and they both refused to fire, yet when inspecting all equipment nothing seemed as it shouldn't be. Although the power settings were perhaps highish there was definitely significant down time between shots as discussions surrounding group dynamics took place (ie it just wasn't that intensive). I often had to turn all units off (triggers and flashes) and back on and try again, which seemed more often than not to fix the issue. Battery levels inspected and all came back fine. Changed coms from short to long, made no difference (flashes were pretty close by, within 2-3m from trigger which I think is fine for close range anyway?). It was just annoying, maybe a good 25-30% of the time misfires for the formal shots.
Mind you this was just on that occasion, later in the evening I set up a softbox with one flash and had no misfires (different location). So it feels like it could be 'environment' (even though both locations were outdoors) or perhaps more misfires occur when two units are involved rather than one?
So...
- Do I change channel? As currently I am just using the standard Channel 1 etc. Have people changed channels before and experienced better success? What's your fav channel!?
- Try other batteries? I say this only because some people have mentioned in Godox groups that the Xpro trigger is less reliable than their older Godox triggers, some users report changing from rechargable to alkalines made a big difference? Hmm...
And so some other issues with Cactus;
- I have a large 120cm octa softbox which is great, I can also put two rf60x units inside for additional power if need be, however with the misfires I am a little uncomfortable about placing two inside because I simply cannot verify when setting things up and judging the light and getting my power settings right, are both firing or only one etc. And if one stops firing in a session and the other one is firing, it should be obvious but then its hard to tell if the ambient light has changed etc. I really appreciated the fact that on the wedding day I split my flashes up and so could 'keep an eye on them' as I took the shot ensuring both were firing. This ability is lost once I place them both in softbox. So... do I make one be optically triggered instead? Or can you buy a cable which connects one speedlight to the other and triggers it? I'd actually rather have a complete misfire and nothing come out of the softbox rather than 1 firing and 1 not etc.
- I noticed with the V6ii, if I turned on all the flash units and connect things up, say I had flash A and B on, and A was at 32 and B 64 (manual power I mean), when I adjust the power it adjusts it globally, which is fine, I can increase power so that both are at maximum (so flash A is 1 and B is 1), however when decreasing power it didn't make them move together back down at the same power adjustment. A would stay at 1 and B would go to 2>4 etc and then flash A would then start to decrease (in essence it recalled their initial differences in power settings). How can I make that not happen? Like get both flashes to adjust in power at the same levels when toggling up and down? Does that make sense? I think the only way is to recall what power one flash is, turn it off on the V6ii, adjust the other flash to being the same, then toggle the other flash back on the V6ii and then adjust, is that right?
- If my K-1 has the Zoom on the V6ii at 85mm and power at full, and the V6ii on my KP has the power at 128 and zoom at 24mm... what happens between the shots taken? Say I take a shot with the K-1 first, and then directly press the shutter on the KP after that shot, is the KP shot still firing the same RF60x units in the settings used previously before (ie the RF60x units will be at 85mm and full power) despite it's V6ii trigger saying something different?
I shall do some testing of my own in this and report back, previously before I just tested if two v6ii units in Tx mode could control the same flashes (and they can) I just never considered how the differing settings on the V6ii units might factor in for the shots taken...
Ultimately I am pretty happy with the system, if I could minimise misfires and also have confidence when I can't see the actual flash units firing that they are both triggered that would be idea. Some of that is just down to experience, like I can tell sometimes that it appears the shot taken one flash didn't go off etc, I'm just not
quite at that place of being experienced enough to know it intuitively yet. It's one thing to get a mannequin out and take test shots, another thing to actually do it with real people on the day under varying ambient light conditions and know with confidence whether both flashes fired or one didn't etc.
TIA!
