Color Shading for M-Mount lenses on Sony NEX-5N

This page offers color shading aperture series for Leica M lenses on the Sony NEX-5N.

Please see the discussion on color shading on the color shading page for the Sony NEX-7.

Be sure to view the Sony/Zeiss 24mm f/1.8 Sonnar as the reference lens; it is free of color shading, demonstrating that a “digital” lens designed for the sensor can address issues that no lens designed for film can.

The Sony 24/1.8 Sonnar is shown for the NEX-5N with both Shading = Auto and Shading = Off. That setting appears to control both vignetting and color shading, and applies only to Sony lenses; it has no effect on M lenses mounted via an adapter.
