I haven't actually tried it yet, but I have inspected the lens with Canon Adapter B plus a ltm-M adapter to see whether it may be possible to mount it on the M9 without touching the sensor. It seems to be a matter of millimeters here. Has anyone with such a lens and the M9 tried it?
How could I try it (very carefully) without messing up the sensor in case the lens gets too close to it? Does it make a difference if you have the RF version versus the FL version?

Any tips are welcome.
 
I don't own an M9 or the 19mm Canon, but isn't the flange-back distance the same on all M-series Leicas? Digital or film?

This is a good point, Jim. I can use the 19mm lens on Leica film cameras, so based on what you are saying, it should be fine with the M9 too.
 
I was told that the J-12 works on the M9, and I just compared the depth of the J-12 with that of the Canon 19, with a Canon P with the back open.
I think, the J-12 gets closer to the film plane than the 19mm lens does, so the 19/3.5 should work fine on the M9 .... hopefully!
 
I have tried it now. The lens fits the M9, but there is a lot of vignetting that is blatant. So, the lens should not be used on the M9.
 
I have been using my Canon 19 LTM on a Leica M8 since the camera first came out and am having no problems. You might run into problems with fringing on the edges and corners of the frames that is caused be the rear element being so close to the sensor that light does not enter the sensor at right angles.
I would like to see your results. Please.
 
Gary,
The M8 crops 33.33% off the image, so the vignetting portions of the full image will not show. I will upload some results.
 
There is strong vignetting.

Hello Roger,
What does such asymmetrical vignetting suggest to you? The M9 works fine with other lenses.
There is also some red banding.

Dear Raid,

Dunno. Off centre mounting, maybe? I've never seen anything quite like it. All suggestions gratefully received!

Cheers,

R.
 
Your example does not look that sharp Raid. The asymmetrical vignetting could be internal elements out of alignment. My old 21/3.4 Super Angulon vignetted evenly around the frame.

Is there a light baffle around the rear element?
 
The light baffle was removed by Eddy Smolov from around the rear element. I do not see such vignetting on film.

 
Then it has something to do with the closeness of the rear element to the sensor, and how the sensor is receiving that light.
