Raid - congratulations on your step up to RAW.
Now it's time for the next lesson.
When I use my CV lenses I set the M9 to "manual lens selection" for the nearest-equivalent Leica lens, because my lenses are not coded. For the CV 21/4 I set it to the 21/2.8 setting. (I then save this as a pre-set, but that's in a later lesson.
When I import the DNG file into Lightroom, I still have to apply the lens corrections based on the lens profile. In the Develop module, on the right side of the screen, there's a tab for "Lens Corrections". Under that tab there's a tick box to be turned on, then there are four other boxes with selections. You can play with the selections, and turn the tick box on and off to see the effect of the correction on the image.
Below the "Lens Corrections" tab there also a tab for "Effects", where you can control the correction for vignetting, or use it to apply vignetting where that is desirable.
Even with the lens profile selected in the camera, I find I need to make these corrections manually in Lightroom to get the photo to look the way I like.
Good luck - I hope these new tools allow you to have even more fun with your collection of wonderful lenses.
