I recently purchased a fish-eye lens and while I'll want the barrel distortion for effect on some shots, I'll want to minimize it on others. I use LR 1.3 for most everything, then roundtrip to CS3 for tweaks and back to LR for printing.
Is the built in CS3 correction now as good as anything else out there? I've looked at a few on line and $ isn't an object as much as just getting the best product that will be supported and around for a while.
I'm also looking at PTgui for panos; does it help with barrel distortion too?
