Sony A7R III Pixel Shift: How Distortion Correction Affects Micro Contrast and Sharpness with Sony 24-105/4G OSS @ 105mm

See my Sony wish list and get Sony A7R III and Zeiss Loxia at B&H Photo.

This analysis looks at the Sony 24-105mm f/4 G OSS @ 105mm on the Sony A7R III in pixel shift mode, and how much correcting for distortion degrades sharpness and micro contrast.

Lenses offering even higher performance will suffer relatively more than what is shown here (for a similar level of distortion correction). And that lenses needing less correction will suffer less. And that lower-grade lenses will degrade less. But all will suffer in some area of the frame when distortion is corrected, pixel shift or no pixel shift.
