Just a note, for such a lens it's distortions correction that will remove corners vignetting as it is cropped out rather than vignetting correction.
A 24mm lens with strong barrel distortion has a wider FOV (diagonally) than a well corrected lens. Correcting the image will give a similar FOV than a well corrected lens, but will lose resolution.
Thanks, make a lot of sense, the funny thing is that distortions correction is very effective on vignetting !!!! the dark area is simply cropped out I guess it is better to activate both vignetting and distortions correction
