Distortion for Sony FE 12-24mm f/2.8 GM
Includes a comparison at 14mm with the Sony FE 14mm f/1.8 GM.
Sony does not provide distortion charts for its lenses. This page shows real-world examples with and without distortion correction.
Barrel distortion = bowing-outwards of the image shape.
Pincushion distortion = bowing-inwards of the image shape.
Wave-type distortion = dominant barrel distortion reversing to pincushion distortion, typically well out to the the edges or corners.
Zoom lenses invariably show barrel distortion or wave-type distortion at the wide end along with pincushion distortion at the long end. The neutral point is typically somewhere in the middle of the zoom range, but it can be significantly skewed towards the wide end or long end, depending on lens design.
