Yes, I agree with that, an excellent tool.
I have used it for correcting a few ZDs and it works well. For some reason
I expected that the distortion might be different for various examples of
the same lens however they must be reasonably consistently distorted -
useful to know.

PTLens' methodology based on actual measurement does a wonderful job on
this kind of distortion. I'm sometimes amazed how squirmy lines
straighten out. It's also way faster and easier. In most cases, it picks
up camera, lens and focal length from EXIF data and does its job without
any input/adustment on the user's part.
