There was a test on DPR I will try to find back comparing DA*300, DA55-300 and Tamron 70-300.
DA* is superb of course but the 55-300 holds its own pretty well even at 300mm. The Tammy shows sooo much CA it is completely destroyed by the DA55-300. -- Thibault Massart aka Thibouille ---------------------- Photo: K10D,Z1,SuperA,KX,MX, P30t and KR-10x ;) ...
