@@kiyo_snaps Shooting Leica style wide angle lenses on a digital sensor can cause a red shift vignette on digital sensors. There was some discussion with Leica bodies some years ago. I shoot a Voigtländer 28mm and the Leica Summaron 28mm on Canon RF FF bodies and I experience this with some critical subjects in the frame. I do not know whether the sensor of the M11 is free of red corners, but I expect Leica to have modified sensor technology with this in mind.
