Make 15 clicks from magenta towards green and 5 clicks from blue to yellow. Magenta cast is gone then.

Thanks Don, it helped a lot, but made the faces a little bit greenish and yellowish.. so I tried 7 clicks to green and 3 clicks to yellow and now everything looks much more natural..

Just warning everyone that this 2.6.0 firmware update completely bricked my M11. I've owned the M11 since the beginning, did every update successfully, but this one bricked it. After performing the update through my iPhone, the camera started displaying error messages I had never seen before. It also took photos that I couldn't view (photo briefly showed in preview after shutter action then disappeared). Then my camera displayed 0% battery even though the battery was fully charged. Now it doesn't turn on at all, even if I remove and replace the battery, or with a different fully charged battery. I'm sending my M11 to Leica for repair.

The only funny part is I did this update to finally solve the freezing issues (no, they were never fixed in any previous update), only to get my camera bricked.

and you were not able to fix it? Do you have to bring the camera to the service?

I can't rule out that there are differences in the basic white balance calibration between individual camera units. It's possible that you might achieve a harmonious result with a less pronounced adjustment than the one I suggested. Generally speaking: don't change anything if you find everything acceptable. However, if you perceive the result as having a color cast, you now have an excellent opportunity to make your own adjustments with the new firmware.

Surprisingly, I now find the automatic white balance on my M11 so reliable that I only make occasional adjustments in post. By the way, I always use the Adobe Standard profile in Lightroom for DNGs, and sometimes Color, Vivid or Landscape for landscape shots. But never the specific profile for the Leica M11. I find that fundamentally oversaturated. I don't know why it even exists.

Very useful, thank you. I gave up on AWB with the M11 a couple of years ago, and just permanently left it on daylight 5500K. Will maybe try AWB again, see if things are better now. Would have been preferable if this workaround wasn't required, and a more accurate colour balance was baked into the sensor. But fair play to Leica for at least addressing the issue.

Using a fixed WB setting like daylight oder a fixed Kelvin value will not prevent the magenta shift. It only sets a fixed temperature, but not a fixed tint.  But if you adjust the WB setting with the new feature, you will get a better white balance in all settings, automatic or fixed.

Me too, and then realized how much better the output is with that setting, so I changed all my cameras to use one of the predefined WB settings instead of AWB.

Reminder:

This thread is about the Leica M-11* firmware 2.6.0

 

Oops. I wonder why they don't deliver the firmware in some big luxurious packaging. Maybe they could even charge for it to improve the experience over a dull file download. 🙂

i had no issues installing the new 2.6.0 FW on  my M11-D via its SD card, and the camera just works fine - but what doesn't work is that my son's new iPhone 17 with iOS 26.0.1 does not connect anymore with my M11-D, be that with the last beta RC2 FW, nor now with the new 2.6.0 FW.  the connection wheel just keeps spinning.  yes, both devices were rebooted, the settings look right on my m11d.  we assume it has to do with some new security settings/features in iOS26.0.1. 

anybody out there who experienced such and knows of a solution ?

If it's a new phone you might need to reset pairing information on camera by press and holding both thumbwheel and function button for 10 seconds (see the countdown in the viewfinder). Then you would have to remove it from FOTOS and add it again following normal procedure for pairing. 

It's a bit annoying but when switching iPhones (maybe Android too?) all bluetooth connected peripherals have to re-pair, only Apples own accessories like AirPods have smart pairing that can be transferred between devices.

that's amazing, @maxpower , exactly what we need here, thank you !  i wasn't aware at all of this section in the manual - i guess i still was with the m10d manual, neglecting new 'features' that were meanwhile added to the m11d's.

as always, it amounts to the infamous RTFM...

I’m getting extreme over exposure situations.  Thought this was gone ages ago.  Reintroduced with new firmware?

I hope this isn’t the case. My first and second  m11’s had occasional extreme over exposure when using Auto ISO. Has not happened with my new M11 BP and I hoped it was gone forever.

[Derbyshire Man]

I’ve had one too

[Peter H]

Apologies if this has been addressed elsewhere and I haven't found it, but can anyone suggest why the latest firmware update worked perfectly on my M11 but using exactly the same procedure, I can't get it to work on my M11M?

In the Camera Information section on my M11M , in the Firmware subsection, the "Firmware Update" remains stubbornly greyed out, whether I use the card from my M11 or a newly formatted card with a fresh download.Yet the same process in the M11 worked as it should.

Ought I be doing something differently?

Many thanks.

Only thing I can share is I had same experience when I used the UHS1 card I have previously used. After several attempts I 'just wondered' and tried a UHS2 card (double row of contacts) and that worked fine.

Thank you. It’s weird, and so frustrating. 
 

I’ve tried the newer card that’s in the  Monochrome; didn’t work. 

Then I used the same card that I used successfully for the Standard M12; didn’t work. 
 

I’ve tried everything I can think of. I can’t get it to work.
 

It doesn’t matter too much for using the Monochrome at present, but still, it ought to work, and it reduces my confidence in future Leica updates generally.

Are you sure you had the M11M update file on the card? (The M11 update file will not work…)

Hallo,

Look here: Interesting Leica gear

[lct]

Stupid question, are you sure the firmware update file is the same for both cameras?

Ah… Thank you… I thought it was the same update for both because I couldn’t find a different one.. the heading on the updates implied it was for all versions of the M11… 

I’m hugely reassured that it’s my stupidity to blame rather than leica’s!

All I have to do when I get home is to find the Monochrome-specific update. 
 

Very  many thanks.
