DFA 150-450 vs DA300 with 1.4 Convertor

The DA 300 with convertor would offer a substantial weight savings as well as slightly lower cost for cropped images. Is there a trade off in image quality compared to the DFA 150-450? Have any of you actually made the comparison?

If this subject has already been covered please point me in the right direction.
