A Test Photo
A Test Photo
Thanks hepcat for posting the photo of the apartment with white walls. To me, there seems to me to be a slight color shift towards red in the bottom left corner and a shift towards blue in the top right corner. It's difficult to see, though, because of the lighting variations due to the angles of the walls and the position of the window.
I searched the web for photos taken with the Leica M9 and a Voigtlander f/4 20mm lens. I found one taken of a white wall as a test shot by
Matthew Osborne. He gave me permission to post his photo here. In this photo you can see the discoloration: a reddish tint on the left and a greenish blue tint on the right end.
It was taken in August of 2013. He has more recent upgrades of the firmware, but not the latest of the time. He doesn't know which lens profile he used for the shot. So, maybe if he had the latest updates and used the correct profile, the problem would have been resolved. Again, if someone has all of the firmware upgrades and the lens, it would be nice if you'd post a test photo.
You pose a good question, hepcat, about how often I will use this lens. When I had a Canon EOS camera with a Zeiss 21mm ZE lens and a few others, I used the 21mm lens for specific needs: grand landscapes and for interior shots in which I wanted to show the furnishings and layout of a room. Sometimes I would take only the 21mm lens with me on a trip. I enjoyed the results when I limited myself to this one lens. So I'd like a lens that will perform well in color and won't require me to have to fix the images it creates with CornerFix or other software. If I know it has this limitation, I will be less likely to use it. I've learned that it's better to get the lens that I'm most likely to use and keep, than to get one for now that I will replace in a short time because of its shortcomings. I've done that too many times and thereby wasted too much money as a result. Unless someone posts a good test shot here, I think I'm better off spending the extra money on a Leica f/2.8 21mm lens or a Zeiss Biogon f/2.8 21mm ZM lens.
Thanks to everyone for tolerating my annoying style and for your responses.
