| Yea mine was too, and still is for the first one or 2 focuses after letting it sit. If you start focusing on multiple points close or far away, the thing has a bit of a faint chirp when it reaches the target, then a bit of a small click as it releases the clutch mechanism. Moving back and forth it just has a mild whirr sound to it, just like my DA* 200mm.
The 200 also has the click as the clutches engage/disengage, but not of the chirp. We did have another older DA* model in the office that had a faint chipmonk sound, but it was much much older. Perhaps it is just something that shows up as it breaks in and loosens up?
Focusing otherwise is spot on at both 16 and 50mm. |
