现在对焦准确了，而且对焦速度也比以前快多了，也安静多了，看来还是有些问题。大
光圈（2.0以上）对焦没问题，小光圈焦点还是往后跑，我也试了试17-55 2.8，小光圈
也往后跑，看来要么是我的机身有问题，要么是普遍现象，镜头应该是好的。
回执上讲的是：
Your product has been examined and it was found that the adjustment of the
AF assembly was incorrect causing front focus. Electrical adjustments were
carried out on the AF assembly and product functions wee confirmed. Other
inspection and cleaning were carried out.
还说cleaning carried out，我的本来就是全新的，送回来时前后镜片上反而多了些手
