As a past owner of the 18-270, I hope they do better than that on the long end. It wasn't that bad overall, but like the old saying goes, "jack of all trades, master of none". The distortion was not excessive, bit of CA on the wide end, bit soft on the long end... it was that which killed it for me in the end.
