SL2-s users, have you noticed the magenta shift of sl2-s under low light conditions?

Skintone will appear magenta under low light or warm LED light conditions. I have tested it many times with two SL2-s, this is not a problem of white balance. 

I guess that in order to make the M lens perform better on SL cameras, the glass in front of the CMOS that resists infrared light is made thinner, causing the magenta shift.

This problem bothered me a lot when I was shooting video.

No.

No. In fact I'm impressed with how skin tone holds up under low light - unless the light source really is pretty narrow frequency. I shoot a lot in low light, and video - mostly drama & performance.

Must be a problem with LED lights?!?

[Photoworks]

Can you show some samples and tell setting used? otherwise it is  non starter conversation

[mumu]

No, i haven‘t noticed any kind of magenta shift in low light conditions. Not one time during thousand of shots.

never seen this, if you're NOT using Auto WB, then its probably:

a) some kind of LED lighting

b) sensor/mainboard problem

 

magenta IR related color shift in low light? that's fascinating..would love to see some pics of that.

I think in general skin tone leans toward magenta on Leica bodies, but I have never noticed it being more magenta in low light. I frequently shoot a very high ISO's and have not seen this issue.

Also here, I shoot quite often in low light (ISO 25,000) and am amazed how good the results are. Quite often I am working under garish multicoloured lights, which does not help the skin tone but not a sensor issue

no problems here

Agreed. The SL2-S’ white balance leans a tad towards magenta. I prefer to use custom Kelvin presets in C1; others don't feel the slight magenta tint. Overall, the Leica’s skin tones are exceptional and resemble the individual complexions very well. We are talking about nuances here.

However, under houshold LED lights colours in general can be funky, depending on the LED light spectrum design. 15 years ago, when the first professional LED-based film light fixtures emerged, most of them were not convincing regarding true colours and could only be used for back lights. That changed when I Arri entered the scene with super heavy but brilliant LED-based fixtures that emitted true sunlight. These were the first LED panels that I used for key lights. 

 

I would not expect any camera to reproduce true skin tones under consumer-grade LEDs.

no problems using high iso

i have a similar issue only when using the leica color profile in lightroom, they tend to clip the reds, this for sl2s or m10, therefore in cases where i have people, i use the adobe standard profile, it works like a charm. 

[drwatson1234]

Have the same issue in Lightroom as well.  It edits fine when I use Auto WB in LR. But the standard import uses the camera’s WB, and that shifts wildly magenta in low light with people. 

[LocalHero1953]

My import preset in Lightroom sets the profile to Adobe Standard.

I am also not so happy with SL2-s in artificial light, even though I would say it's a bit on the orange side. Could be Lightroom though.

I have the same problem with Leica SL2-s. I've shot the same situations many times alongside Nikon Z6II. In low light or weaker sunset light, Nikon can capture the atmosphere perfectly, somehow connecting everything with the yellow undertones. The skin tones just look spot on. But Leica shifts towards magenta and no WB can fix this. You have to fix the skin tones selectively, but it some situations it is not so easy. I consider this one of the worst things about the SL2-s. In stronger daylight the camera is amazing.

Has anybody tried to use a B+W 486 filter to counter this effect? 

[LocalHero1953]

With longer experience, I can say that I’ve had no problems with low natural light that I can’t fix with a WB adjustment. In artificial light my practice now is to set a fixed WB, around 4000K. With any artificial light that has a frequency component, the WB could vary. Perhaps some cameras average WB over a longer period than Leica does.
