I have tried a few copies of this lens, and settled on the one that was best among them. In spite of this, I do see significant field curvature in landscape shots (read: focused close to infinity) even at f/8, meaning that not even at f/8 will it be possible to have decent sharpness from one edge to the other.

And that's a pity, because I think at least one review said it was better than version I in this respect. I'm not sure what focusing distance they were referring to there, though.

As pointed out, curvature is not something that is usually adjustable, it's part of the design.

This might be an interesting read:

Question to all owners of this lens: what are your own copies like when focused at something distant? I'm starting to think that this lens is just not designed for use with landscapes at all, but rather optimized for shooting at closer distances.
