comment:I am very happy with this lens. I think it is very good overall, and amazing in terms of distortion control.

To be honest, though, it has serious drawbacks as well -- which I think are understandable physical compromises given how wide it is. But you should understand the shortcomings or else you may be sorely disappointed. For me, the most disappointing aspect is that the lens is not very sharp at all. It's not horribly soft; it's fine. But even stopped down pretty far, it's not what I would call sharp.

If I could justify the expense, I might have gone with the CZ 16-35. But this "compromise" lens has the advantage of being significantly wider!
