Optical Distortion for Sony FE 35mm f/1.4 GM

This page shows uncorrected and corrected examples of the pincushion distortion of the Sony FE 35mm f/1.4 GM.

Distortion correction for pincushion distortion has the side effect of visible loss of micro contrast over all of the frame.

Includes images up to full camera resolution, plus crops.

Example: Old Mining Buildings
