Thanks for reminding me Chuck (I've known about PTLens for quite a while),
bought the license and it's doing a great job of fixing the curved images
from the ZD 14-45mm. I especially like being able to fix the perspective
when the camera isn't perfectly parallel to the subject (e.g. hand held
archi images).
