Sony / Zeiss FE 16-35/4 ZA OSS Vario-Tessar

Distortion Examples @ 35mm

This scene shows optical distortion at 35mm, and its corrected version.

Correction was using the Photoshop lens profile during raw conversion. Sony ARW raw is never corrected for distortion by the camera (JPEG is however, if the camera is set to do so).

Example @ 35mm

The uncorrected image has moderate pincushion distortion (bowing in). At least to your author, pincushion distortion this strong is much less visually acceptable than its equivalent amount of barrel distortion. It is enough that correcting it seems “required” aesthetically.

Observe that correcting pincushion distortion crops off frame edges at opposite sides. Framing slightly wider is thus advised.
