Nikon Z6III weird flicker issue

[sagavortex]

Hello,
I have a weird issue with my Z6III camera, I noticed it during a shoot at a musical event with lots of flashing lights/LEDs. I have flicker reduction turned on.

Check the image. Does anyone know what causes these lines? How can I avoid them? Is it the partially stacked sensor?

It should be from the stacked sensor. What is happening is the light is changing as the image is read off of the sensor. Stacked sensors read multiple zones at the same time instead of scanning the entire sensor top to bottom in one large inclusive scan. So the banding is the change of light happening during the exposure time.

If it were film, the light would average evenly over the exposure.

So would using mechanical shutter fix this?

I do not have one of these cameras yet, so I cannot answer that with confidence. But I have watched the phenomenon explained in videos. It interests me knowing someday I would be looking to buy a body with stacked sensor.

From everything I've read and seen- YES- choose mechanical shutter for LEDs if you have it.
Or keep under 1/250 sec- but even that may show some banding. I've a friend who shoots for Chicago Lyric Opera and has a Z6- and he was having that issue badly at 1/400 sec, reduced greatly by keeping under 1/250, but not gone completely.
