It's usually a Catch 22. You correct the distortion optically and you end up with a less sharp lens. Not correcting the distortion may actually result in a larger lens, which you have to downgrade by fixing it in software later on. Which results in a pretty similar image. There are exceptions to the rule, which are both well corrected and sharp all the way but those lenses are usually much larger, heavier and more expensive anyway.

So, I don't really care. Apart from very cheap kit zooms, I never noticed any quality loss after clicking auto-correct with any of my lenses.
