Leica M9: Color Shading for 12 Lenses With/Without Lens Correction
Published in Guide to Leica is a new page showing color shading with and without lens correction for 12 Leica M, Zeiss ZM and Voigtlander M-mount lenses. I hope to add more soon.
By showing color shading both with and without lens correction on the M9, one gains insight into potential performance issues on the Sony NEX-7 and similar cameras (not to mention the color and vignetting themselves on the M9/M9P).
