M10M with April 2021 manufacture showing the issue. It's subtle, but visible even without adjustments if the subject is an even tone like the sky. I'm not seeing a dark line, only this slight difference in exposure between two halves of the frame. This sure seems like something Leica should try to fix in firmware.

Light red filter used, plus substantial use of dehaze, clarity and contrast added to the sky in Capture One, but it was still visible in the unedited image. If I were to make a large print from this, it would be clearly visible (it's less noticeable sized down for web here). I don't think Leica's excuse that this only happens when the image is heavily processed holds merit – Editing to produce an Ansel Adams-looking sky is a reasonable use of a monochrome camera.

It looks like the calibration used to bring the two halves of the image into agreement is not good enough.

Try shooting some images of a grey card and bracket the exposure values. -4, -2, 0, +2, +4. Try at different ISO settings. If the left/right agreement changes, that should indicate the issue is the calibration.

Here's an $11K camera. Please be careful though how you edit, we only allow certain artistic freedoms before our defunct engineering starts showing at the seams.

Update on my situation, I am demanding a refund from Leica. I am not convinced a 6 month trip to Wetzlar will resolve the issue. There is a fundamental engineering flaw here and the camera should never have been allowed out the door. I've lost all faith in those that evaluate these cameras and give glowing reviews without having done a truly thorough job. Reminds me of the M8 fiasco all over again. Fool me once, shame on you, fool me twice, shame on me......

Excuse me?  One of the most succesful digital cameras Leica ever built which saved trhe company and an anomaly in the camera world for the number in use after all these years... It is very hard to place the word "fiasco". And six months is hyperbole, to put it mildly.

Dealer returns for full refund (typically 7 days) require no explanation, although of course one will want to share, especially if exchange is preferred.

Yes, this seems like this is something that Leica could (should be obligated) to fix with firmware. I’m assuming Leica must have eyes on this forum?  Perhaps the first challenge will be to get them to acknowledge that this issue exists.

Anything that affects contrast will affect the visibility of the difference between the halves.

I can shoot the light gray ceiling in my house and see it.

Someone already got a response from Leica and posted about it earlier in the thread. It sounded like Leica already knows about it and brushed it off as expected behavior due to the way the sensor is manufactured.

The challenge is getting them to see it as an issue they need to fix.

That would have been me. Three sensor artifacts with my copy, only one acknowledged by Leica (as posted), but remarkably not as a defect. I’m a fraction away from dumping every last bit of Leica kit at this point and moving to another system. My 25 year relationship with this manufacturer is close to the end.

My Q2M did not have this split-exposure issue, so the problem is specific to the M10M sensor. Thinking I will return the M10M and put the money toward a 28 Lux for my M10-R. I'm guessing the demosiacing process from the Bayer color filter array on the M10-R more effectively hides or negates the split-exposure issue.

Thankfully, I’ve had no such issues with either my M10-R or SL2.

I sincerely believe that the issues are incidents, which doesn’t mean that Leica hasn’t to solve them.

What does that even mean and how does what you believe have anything to do with this? I can reproduce this issue at-will. It shows up on an any even-tone background with added contrast, sometimes being visible with no adjustments.

As I’ve written before in this topic: I pushed LR to the extremes with several pictures, but I cannot reproduce it.
