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.
