GIMP :: Using Lens Distortion Filter (2011)

There used to be a pnorama tools plugin which allowed one to entercorrections for specific lenses which I was able to find on the web.That worked very well. But I haven't been able to find that plugin forrecent versions of gimp.

There is a lens distortion filter, but you have to use it by trial anderror. I haven't found any specific recommendations to use forspecific lenses anywhere. And in some cases, nothing I try works. Iattach an example below. It was taken, I believe with a Nikon 18-55 mmlens at 18 mm. You will notice that there is no distortion at thesides but significant barrel distortion as you move in from the sides.No combination of major and edge correction that I've tried does anygood.

P.S. I understand that ahd I shot raw with my Nikon, I might havebeen able to do the correction more easily using ufraw. Also, it mightbe possible using hugin to correct the distortion. But I would like tobe able to do it with gimp if I can.
