I have a 16mm f/2.8 Nikkor fisheye, which I can't really use on my D70
because of the crop factor. However, I know that the 10.5mm DX can be
corrected to rectilinear in Nikon software. Surely the same thing can be
done to any other fisheye lens in Photoshop?

I was wondering if there are any plugins or actions one can download for
PS to transform output from the 16mm into a rectilinear 24mm lens?

PTLens works well, and gives you the very valuable option of correcting
vignetting and chromatic aberration as well. I tried correcting 16mm fisheye
to rectilinear. It certainly works, but you have to keep in mind that the
16mm is not a particularly sharp lens to begin with, and by expanding that
you end up losing even more quality. Actually a cheapo 24mm or the 24mm
setting on a cheapo zoom would probably end up being superior.

The 16mm on DX is actually quite nice, I find, without correction.
