And, FWIW, fish-eyes can be defished; right?

But if you're going to "de-fish" your fisheye images (and restore the distortion that fisheye lenses don't have), then what's the point of using a fisheye lens in the first place?

Perhaps you already have a fish-eye if it can be defished there's no need for a rectlinear also.
Or perhaps you have a fish-eye and have the flexibility of using it either way.
Not saying you need to run out and get one; just options.

Some might not agree, but my position is this.  Unless you plan to shoot undistorted star fields, your better off getting a rectilinear w/a lens.  While correcting for distortion is possible in PP, I believe the less done, the better.
