Lens detection for an M camera does not correct distortion, but only vignetting. Though Lightroom may apply a "correction" of distortion if you enable the "profile correction" and it detects a certain lens profile. 

I haven't used LR for a long time but 6-bit coding does correct for vignetting on my M240. Just applied the 35/2 lens profile to the Summicron-C 40/2 on this body and the same correction works as well. Thanks for correcting me.

The Summicron-C 40/2 is not coded by Leica, reason why you won't find it in the lens profiles list of your M11 i guess. The lens has the same moderate barrel distortion as the Summicron-M 35/2 v3 more or less so you can choose the profile of the latter. It won't correct for anything else than distortion though if the M11 behaves like my M240 and digital CL from this viewpoint. 

Edit: The code number of the 35/2 v3 is 11309. If you don't find it in your lens profile list you can choose 11310 or 11311 instead. Those are the code numbers of black and chrome Summicron-M 35/2 v4 the distortion of which is very close to that of the 35/2 v3. I would not choose the profile of Summicron-M 35/2 asph lenses though (11879, 11882) as they have a mustache shape distortion. 

Many thanks. I found the 11310/11311 in the menu and are using that.

I had had this lens sitting in my dry cabinet for years. I thought I had put it away 'never to be used again' because of a haze issue. Now with my nice new M11, I thought it might be nice to use it again with an accurate FOV through the EVF. But first, I wanted to remind myself how bad the haze was, so did the 'holding up to the lamp' test. Surprisingly, there was no haze ?!?!, just dust. Have done a few dozen test pics and it is as sharp and clear as you would want. Very odd, but now I have a great little lens I thought I had lost.

An example attached. F2.8, ISO 64.

Really happy to have recently scored a second copy of the rokkor version of this gem .  
 

Of course this pulls up 50mm frame lines on M bodies but now I have 2 of them I’m thinking to swap over the mount from a 28mm m-rokkor on one of them as I think this will pull up 35 frame lines on the M.   The un-modified version will continue to trigger 40mm framelines on my minolta CLE  

(the seller had a copy of the 28:2.8 rokkor with the white spots problem that those lenses had, so threw it in the deal as a write-off). 
 

life is good !

For those using this lens on digital, what lens profile do you use in the lens detection menu?

I could not find the Summicron-C 40mm in my M11's lens menu, so I just used the 35mm/f2 as a proxy. Of course, looking through the EVF is fine, and it exposes fine as well, but of course the lens info in the metadata is wrong. Not a biggie, but curious what others have done.

This lens is basically the exact same double Gauss construction as the Summicron 35/2 V2 (or V3) so any of these.

If I buy another cron it would be v2 or v3 for this reason. Although I think the little extra compression of the 40mm makes it really nice.

The rubber lens hood on mine came apart. As I am using it on the digital CL, I found out that the rubber lens hood of the matching 90mm Elmar-C fits nicely onto the Summicron-C and does not vignette at all, the CL having a smaller sensor.
