Does the Sony FX6 VND not work in certain settings/modes?

[Nailer]

Hi, my first time posting and was looking for some help.

I thought I’d try out a few shooting modes that are new to me but seem to have come across an issue. I’ve turned the camera to 4k/CineEI/S&Q mode (100 fps/25p). Everything seemed fine at first, I was doing some tests but after a few mins the VND stops working. On the camera’s screen the VND numbers are changing but it has no effect on the image. I turn the camera off and on again and it works again but then stops again after a while. 

I've tried various tests with some of the above settings on or off and it all seems to work ok except when I turn on S&Q. 

I’m presuming this isn’t right but would appreciate anyone’s thoughts on this. Thanks

What are your other exposure settings?  It sounds like Iris, Shutter Speed, or Gain/ISO might be set to automatic and is then cancelling out the changes you make to the variable ND.  https://vimeo.com/ondemand/fx6

Please provide more details or, even better, shoot a video with your phone that shows the settings on the camera's LCD screen  while you adjust the VND.  I'll bet that will show exactly what the issue is.

Thanks very much. Everything is set to manual but I’ve attached a video. As you can see the variable nd numbers are moving but the image isn’t changing. It was adjusting the image/exposure when I first turned the camera on.

That's very strange!

Wondering if it's perhaps faulty? Have you tried a hard reset of the camera?

If you put the ND on "Auto" does it work?

Is the lens iris auto or manual?

Is this maybe something to do with the Bokeh Control setting? Is that On or Off?

Videosoul is correct, this is very strange.  I spent about 2 hours yesterday matching all the settings on your camera that I could see in the viewfinder and trying to recreate your problem.  No matter what I do, VND functions normally.  So, I then reached out to one of the top techs at Sony overnight to see if he could figure it out , but he's stumped as well.

Here is our advice:

STEP 1:  First of all, make sure your camera is running the latest firmware, which is V4.0. If it is not, then you can download and install it here.

STEP 2:  RESET the camera:
Menu > Maintenance > All Reset

STEP 3:   Load my custom ALL File.
After I matched all the settings on your camera (at least the ones I can see) I saved an ALL File.  You should download my ALL file via the link below and load it into your camera.  It will be called "VND-TEST1" when you see it in the camera's menu.  After you have loaded the ALL file, check to see if the VND functions correctly now -- it does on my camera with those settings.   If you still experience the same issue then there is probably something wrong with your camera.
ALL FILE:     https://vortexmedia.cimediacloud.com/r/PIFxEvRjExYn

Disclaimer:  Just to be clear, none of the settings saved in the "VND-TEST1" file are settings I would ever use myself except for 4K XAVC-I.  So, if anyone else is reading this thread, I do NOT recommend the settings in this file. I'm just trying to troubleshoot Nailer's problem.

STEP 4:  Report your findings! 🙂   Good luck.

Apologies for the delay in responding. I really appreciate your efforts Doug in helping me. So short answer is I’ve just done a reset and it seems to be working.

Before the reset i did a double check and it was faulty still. Since the reset I can’t get it to repeat the same issue. Touchwood this isn’t temporary because sometimes the fault doesn’t happen immediately. But I’ve done all my usual tests that trigger the fault and so far nothing. 

Thanks for your help also videosoul  - I tried auto nd and the fault still happened. Bokeh control was off and i tried iris on auto and manual and it still happened. I’m on the latest firmware also.

Hopefully all is well now. Thanks again.
