Sony Kolarivision A7R.MOD: Performance with Leica 50mm f/2 APO-Summicron-M ASPH

See the prior posts: Sony A7R: Sensor Glass Thickness, Ray Angle and Image Degradation: Kolarivision Modification and also Modified Sony A7R Sensor Glass: Impact on Rangefinder Lens Performance.

This 2-way comparison demolishes the idea that a 50mm rangefinder lens is free from the damaging effects of ray angle, a fact sshown 9 months ago in the 50/2 APO mosaic aperture series. But the A7R.MOD versus stock A7R can leave no doubt.

In Guide to Leica:

Sensor Cover Glass: 50/2 APO-Summicron-M on Stock vs Modified Sony A7R (Mosaic)

Includes HD images up to 4320 pixels across the f/2 - f/11 aperture range as well as HD crops from both the stock A7R and Kolarivision A7R.MOD can be easily compared. With commentary.
