Hi guys. I find that the camera produces a slight barrel distortion and therefore, after some tries, I created a preset in Lr that automatically applies a +4 Distortion correction (from the Manual section of the Lens Correction panel) on the .tiff files created from SPP. I am quite happy with the results. So I thought to share this information and besides that I would like to know if any other user found the same issue with their images or if somebody is applying different corrections.
Saluti,
Luca
