How to upload images: Prepare the image as follows: 1.   The image should be sRGB and 8-bits 2.   Reduce the size to 2048 pixels on the longest side. (smaller sizes can be set, but are not recommended) 3.   Sharpen properly for screen. 4.   Save as JPG to your desktop, reducing JPG quality to produce 2000 kB (5000 kB for sponsoring members). 5.   In Lightroom these parameters should be set in the Export dialog. 6.   In the Forum posting or editing box, click “choose Files” and s

It does struggle when it comes to colour balance. 

Agreed. Something seems a little off with AWB in some situations. Not sure I can articulate the circumstances yet.  Seems good in daylight, but indoors things start to go off in ways that I never encountered with any previous M.

35mmLux  pre Asph  weird banding showing in the sky that is not in the Raw file

I've had a similar issue with my Q.  In my case, the out of camera jpg was fine (I always store both jpg and raw).  For some reason, the PC operating system somehow screwed up raw files when converting them (sometimes).

Can you describe in more detail what and where the "weird banding in the sky" is, in this photo?

Have you identified the 35mm Summilux pre-ASPH to the camera using the lens menu, when using that lens?

If you mean the sky in the center of the full image is pinker than on the left/right sides - that looks like a little residual "Italian Flag" syndrome from the 35 pre's short and close optical design interacting with pixels. A problem that Leica (about 2004) originally said meant they would never be able to make an M digital (but under market pressure, they learned how).

Here's a more extreme version from a 35 pre Summilux on the M9 - which didn't support the 35 pre Summilux at all. Note that the pavement is warmer in the middle, but more blue/green on the sides/corners.

Since you have identified the lens, that may just mean the M11 firmware is failing to correct the "Italian Flag" stains perfectly.

Not unheard of - when the M9 came out, the "lens correction" the camera applied to the supported 21mm pre-ASPH lens was not correct in the initial firmware, and it took Leica close to a year to get a firmware fix issued.

Supposedly the BSI sensor should also reduce this (shallower pixel wells) - but it does take very careful progamming, especially for scenes with continuous smooth tones like a sky or that concrete above, or snow. Has to be recalculated for each new sensor design.

The only other thing that might be "banding" that I can see are some very, very faint "spokes" or smudges radiating out from near the top of the power pole? I have no idea what those might be - or even if I am just seeing things.

Interesting point Andy.  That's why i asked Artin earlier if he had any after market wide angles to test for this edge phenomenon.

It's very prevelant on my M-P 240, and i make excuses that it is easy to fix in LR.  But it's still an irritating bother.

I asked Artin to try with a CV 15MM F3.5  v1 ltm which shows the problem particularly well.

Perhaps someone else has the M11 and can show definite "Italianflag" affects.

Many thanks, i would be most appreciative, as i won't think of considering another digital M with this problem.

The good news is that it IS just a firmware problem - minor rewrite of some firmware code or a look-up table, and it is fixed.

The in-camera processing will then remove some blue/green (or add pink) on the long ends of each picture taken with that lens, in a "known" pattern specific to the lens, before commiting it to the SD card as either jpg or DNG. As they have for the M9/M240/M10 and sub-models previously.

[(   )]

Probably won't take as long as the M9 rewrite did - but I'd suggest Artin and other 35 Summilux pre-ASPH users submit some sample .DNGS made with that lens to Leica - showing the problem clearly on a neutral background like the sky, or a snowy field - soonest. Just to get the ball rolling.

I'm going to guess the 35mm Summilux pre-ASPH was simply not a lens used much (if at all) by the various M11 Beta-testers, and thus no-one noticed its corrections needed a tweak.

It is a terrific lens, and AFAIK well-supported (in the menu) by the M10 - but not used by everyone. And in translating M10-ese to M11-ese, it got lost in translation. Welcome to revising computer code. ;)

Now, the 15m C/V v.I/II is not Leica's problem - they support only the lenses they build.

And C/V redesigned that lens's optics to fix the "digital" problem anyway (v.III)

I have noticed that there are many posts in this thread that do not relate to the images shown. People come here to look at the photographs with the M11, not to see text. Please use the multiple other threads for discussion. From now on posts that do not relate directly to the images will be deleted without notice.

fyi, in all my leica cameras i turn lens detection to off, and never noticed any of these issues with my lenses ranging from elmar 35 f3.5 all the way to cron 35 v1, hektor 28mm and so on and so on…or at least i never noticed..doesn’t seem like a big deal to me..and I’m sure the M11 will be just fine

I really love the colors. They are so different from my SL2-S. A bit like Kodachrome. I was struggling a bit to get the pictures right in LR. This one was taken with the Apo-Summicron-M 1:2 90 mm Asph, 1/200, f2, ISO 1600. Edited in LR with original M11 profile.
