To customers who have purchased the SIGMA 30mm F1.4 DC DN | Contemporary lenses for Sony E mount:
– In the camera setting, select “Auto” in the distortion compensation from the lens compensation menu.
– If the camera does not incorporate the lens compensation function, the lens cannot offer distortion compensation.
* Sony cameras have a different image circle from those of MFT, so the distortion data above is not the same.
