Avoid the 21 mm f/4 Voigtlaender on the M9

As Ken Rockwell wrote, I can now confirm that the Color Skopar 21 mm lens, made by Voigtländer and sold for around 350 Euros in Germany should be avoided on the Leica M9 because of heavy vignetting and some color fringing. Although this picture was taken with this camera / lens combo, the vignette was corrected in post and color fringing irrelevant because of the desaturation.

Happy shooting, Carsten
