Lighroom 6 Leica SL Leica M Lenses manually lens correction

I have the following problem. I use my SL with Novoflex Adapter and several M Lenses from Leica Voigtlaender and Zeiss. The Lens Correction function is turned off in the SL, i like the vignetting in the jpegs. When i try to edit the dng files from the SL I can´t use the Leica M Leica Lenses profiles. The Voigtlaender and Zeiss work perfectly. To buy the original M Adapter from Leica is not a solution, i mosttly use old non coded Leica Lenses.  By the way the manually lens correction works perfectly when i use Lightroom with my Leica M240 and Leica Lenses ( and so with voigtlaender etc.)

Any solutions ?

All the best

Clearly as the camera has now way of knowing what M lens you have on, you need to set it manually.  In recent firmware revisions, Leica has tended to write both the lens id, and the necessary correction parameters, into the DNG.  This works nicely with the Leica adapter and Leica 6-bit lenses.  Otherwise, I need to do the same as you and apply a profile manually.

Do you mean that there is no SL option in Lightroom menu? If yes, this is indeed the case, because SL lenses have built-in profiles that do not require manual selection, once you enable lens correction in Lightroom. For M lenses, you simply select Leica M and if you are lucky, your lens will be there. The problem is, Adobe for some reason neglected all lenses of pre-asph period and earlier. So, out of all non-ASPH lenses you get only Summarit line and 50mm Summicron, which does not really require any correction :)

We seem to be assuming that Lightmover is using Adobe LR to develop DNG files, but that should be confirmed.  Adobe doesn't offer lens profile controls for distortion or LCA correction.  The SL, when it knows what lens it is using (either automatically or by selecting a lens profile that seems appropriate for the lens in use) puts these corrections into the DNG.  (You can read them with a text editor -- look for WarpRectilinear -- or one of the EXIF-reading tools.)  Adobe applies them without the possibility of user override or modification.  Capture One and some other toolsets will let you see that they are being applied and modify the amount applied, which is valuable for pictures in which straight lines and angles matter.

Scott, not sure what you mean... LR allows manual distortion and vignetting correction whether the profile is applied or not.

Since I'm not a LR user, I am going on Sean Reid's bitter complaints that LR automatically applies the distortion corrections embedded by the SL into its DNG files, and doesn't offer an override.  The 24 end of the 24-90 zoom is a good example.  There is some sacrifice of corner sharpness in this (extreme) case.  In COne, I can revise those corrections to any magnitude from 0 to 150% with 100% the default if I want a little extra crispness in the corners and there are no distracting straight lines that come out curved.  I usually don't do that, because even with the lenses which have little distortion there are lateral CA corrections that can be put into these terms.
