Here one of my first attempts with this lens. I de-fished using PTGui and then cropped. Still trying to get the hang of de-fishing. Shot at 10mm, 1/20 sec, F19, ISO 800, RAW.

I've never heard the term before, but I havea good idea of what it should do. Correcting the lens distortion would be nice to know - it's the main reason I hardly ever used the 24mm 2.8 lens once I bought it. It doesn't have as much with the DS, and I'll probably use it much more now.

You have it correct. It is a term used to describe removing the fisheye lens distortion of the picture, thus creating a rectilinear image. The fence in this image was quite distorted, and correcting this allows the lines to be straight and parallel. Of course as you can see it's not quite there. It's much easier to take the shot with a super-wide rectilinear lens in the first place, but these lenses are quite a bit more expensive.
