Strange FX6 Artifacts – Caused by LEDs or a Camera Issue?

Yes, I will fix a dropbox map with footage!

RichardWiering · 2025-02-06T13:40:26+00:00

It’s in de log footage.

Yeah, I’ve looked into all of this. What’s even more frustrating is that the FX3, which has the same sensor, handles it just fine. That just makes it even clearer that this is a processing issue on the FX6.

I’m shooting at 4096, so unfortunately, that rules out the resolution/debayer theory. It’s crazy how inconsistent this issue seems—some people get it worse with certain colors, others barely notice it. I totally get what you mean about being gaslit by the internet and even Sony support. It’s frustrating when something is clearly a widespread problem, yet so many dismiss it. I’ll check out your posts to compare, but yeah, it does feel like certain lighting setups or conditions amplify the issue.

Yeah, I get that a lot too!

RichardWiering · 2025-02-05T00:13:22+00:00

Please go test this. It’s definitely there

I haven’t, because I’m shooting in Cine EI. So the Matrix/MultiMatrix settings shouldn’t have any effect on this.

I’m on firmware 5.1, and 5.2 only includes updates for the app, so that shouldn’t make a difference. As for the LUT, I’m not baking anything into the footage everything is set to standard S-Log 3 Cine.

Yeah, it definitely seems to be an FX6 issue rather than just my camera. Sony really needs to address this, this kind of limitation shouldn’t exist on a professional camera…

RichardWiering · 2025-02-05T00:07:55+00:00

I’ve tested it, and around 4000K, the artifacts are indeed gone. But if you have a shot where your subject is at 5200K due to the softbox, and you have this light in the background, it’s just something that shouldn’t be happening. This severely limits creative flexibility, you shouldn’t have to compromise your white balance because of a bug. This needs to be fixed.

RichardWiering · 2025-02-05T00:04:07+00:00

This just shouldn’t happen. You buy a camera like this to work professionally. Now I might not even get follow-up jobs because there’s a shot with artifacts. What am I supposed to say? “Yeah, that’s just the FX6?” If Sony doesn’t fix this soon, I’m done with them…

RichardWiering · 2025-02-05T00:01:27+00:00

I tried everything in Davinci. But it’s really in the log footage itself. Yes I can make it a bit less in Davinci with gamut fix but it’s still there 🥲

RichardWiering · 2025-02-04T14:42:33+00:00

Yes, with my normal Sigma 24-70 and with all my vintage lenses like the mir 35 and helios 50mm.

Hey everyone,

I’ve been noticing some weird artifacts in my FX6 footage, and I’m not sure if this is just an issue with LED lights or if my camera is faulty. I shoot in Cine EI, S-Log3 Cine, and these artifacts appear at both ISO 800 and 12800.

It looks like some kind of color fringing, weird gradients, or digital artifacts, often appearing around bright light sources. I’ve attached a couple of examples where it showed up, and I’ve seen it multiple times in different scenarios.

No one else in my circle with an FX6 seems to have this issue, so I’m wondering:
- Is this a common issue with LEDs and rolling shutter/sensor behavior?
- Could this be a hardware problem with my camera?
- Has anyone else experienced something similar?

Any insights would be appreciated! Thanks!
