Hello, I would like to let you know that currently the lens profile of the Sigma 14-24 dg dn in Lightroom leads to a visible overcorrection of vignetting, especially at 14 or 15mm. This happens when you just enable the automatic lens correction, with distortion and vignetting values set to standard values of 100. I have attached an image taken at 14mm, the automatic lens correction in Lightroom being enabled.
One can clearly observe a white area including a thin white curve in the left and right corner of the image which is kind of disturbing.
Currently I am able to adjust this by significantly reducing the vignetting value to approximately 30-50, but it is only a workaround and it also depends what value for the distortion is set.
It would be very helpful if you could have a look at this and modify the lens correction profile of the Sigma 14-24 for Sony.
