Nikon D750
I just got a Nikon D750 body and TTL passthrough is not compatible with this model. Can you guys release a firmware update to the Cactus v6 to address this please? Thanks!

May I know what flash you are using and how you set it up with the camera , flash and the V6?
FYI, to use TTL pass-through, the V6 has to set in TX mode. The V6 is sandwiched between the camera and the flash hot shoe. Then the flash should work as it mounts directly to the camera.
The TTL pass-through doesn't work in wireless mode because V6 Tx unit doesn't transmit TTL signal to other V6 Rx unit, and vice versa.
Look forward to hearing you soon.

make sure that you've got the flash profile correctly selected in TX mode, when using TTL pass-through. The latter does not activate a hardwired connection but relies on the correct flash profile to be chosen.
I didn't say it was a user error. I just suggested to make sure that it has a chance of working.
I'd suggest to maintain a friendly and grateful attitude since this is mainly a user to user forum that is also monitored by Cactus as much as their resources allow.
Giving me basic instructions on how to use the product properly is absolutely a user error based response. It doesn't matter if you used the term user error.
However, from the picture, the distance between the D750's locking pin hole and the center pin is the same as other hot shoe. When you place the V6 in the correct position to the locking pin hole, the V6's TTL pass-throught can work as it should. We tested it with our D750 and V6 in TTL pass-through mode. It works like a charm.
Hope that helps.

May I help?
The Nikon hotshoe appears to be loose when mounting the flash on the top. It seems that the Nikon camera hotshoe is 1mm wider than standard ISO hotshoe. When the SB-910 is mounted directly on the top of the Nikon camera, then shake the SB-910 a little. You will find a wobble. But, don't worry! The flash is lock securely with the lock pin. So, it won't slide out. The same situation applies to the V6.
BTW, both V860N and SB-910 works fine with V6 as expected in our test. But if you can link me to videos or photos to address the problem. I'm happy to forward that to our engineering team for inspection.

I got home and was making my video and stumbled upon some issues.
1. Four out of five of my V6 modules will lock on my D750
2. One of them won't lock on to either of my D750s or my D4. I think it is defective.
3. My problem was that I wasn't spinning the locking bar far enough, the catch to this is that I have to spin them so hard that I broke the lever off of one of them.
4. Neither of my Godox v860n flashes will lock onto ANY of my V6s.
Second photo shows the broken arm from one of my v6.

We will improve the locking pin in the next production of the V6. If you want to replace it, you can send it back to our once the new pin is available. Please email to our customer service at info@cactus-image.com for more details.
On the other hand, the broken lever is not usual. Maybe you can contact your deal to get it fixed or you can send back to us for repair. Please email to us for further instruction.
Thank you.
