My first 16-50 was misaligned but was replaced by B&H within days. The second one has at least 10,000 frames on it, no problems. My DA* 50-135 and 60-250 each have three to five K frames on them with no problems. Oh, and my two *istDs and my K10D were trouble free. And I work all my gear hard. Paul
