[Leica] Unintentional Vignetting

[Tina Manley]

PESO:

I'm running into a problem with some of the photos that I took from
train windows in Sweden.  I didn't notice it so much in Norway and I'm not
sure why it would be different in Sweden, but most of the photos taken
through the train window show a lot of vignetting:

I can get only around it by cropping a lot.  Any lightening that I try to
do just makes it look uneven.  It is not dependent on the camera or lens.
I get the same thing with the M240 and 35/2.

Any ideas?

Thanks,

Tina
