Unreliability (Nikon D750 hot shoe alignment issue)

edited July 2016 in V6 II Problems
The Cactus V6 II is unreliable.

1. TTL pass through - using a Nikon 750 and SB910, sometimes the flash works, sometimes it does't.

2. Triggering wirelessly - sometimes, the only way for the transceiver to update the power settings on the remote flash is to test fire the transceiver - this then updates the remote flash's settings but seems a waste of power and is inefficient. Other times, the remote happily updates the power settings without having to 'test-fire'. 

3. It is weird that it can't auto detect my Nikon camera and Nikon Flash - ok once I have set the camera and flash to Nikon.

4. I cannot update the firmware (see separate discussion).


This isn't a cheap system but my experience so far suggests I paid too much.

  • Ah, you are using a Nikon D750.

    Try this: https://fstoppers.com/originals/stop-fighting-hot-shoe-your-nikon-d750-110295

    I think the first 3 points are related to the hot shoe alignment problem on the camera model. As Fstoppers' article suggested, you need to extend the distance. Try sticking a small piece of masking tape and see if the V6 II can auto-detect your camera.

    On the firmware I have replied you. There are no new firmwares released since V6 II launched.

    And in your case, it's not a problem with V6 II, but the rather special hot shoe on the Nikon D750.

    Thank you!

    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) but 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.
