It really doesn't just "fix" it that easily. It's still fairly noticeable, and as mentioned in the link is worse than other similar lenses.
Anyway, as I said IMO it's not anywhere near as good a lens as the FF equivelant, be that older or newer ones (older ones being more comparable in price and size). I'm not saying don't get it, just that I don't think it's as good a lens as people insist it is, and that I rarely use mine because of the issues mentioned.
