Yeap. Please do a very thorough check on the Af as this is most of the problem with this lens. other than that its a very good lens. In terms of many ppl getting blur images, i do too. I read somewhere that its actually how you take pictures. Most of us will usually AutoFocus>half hold> then Frame picture>then SNAP. And because of the 1.4 bokeh, even the slightest move from the subject will create blurness. Thus when using f1.4 its better to frame, use the manual focus point to aim on the subject and Snap. Thats what iread.
