Ouch. I sent my 55-200mm Nikkor flying and it fell about 5 feet onto a wood floor. Now it's kind of "sticky" and tight to zoom...not as fluid throughout the entire range. So far the images from it look ok but I haven't checked it out too well. The autofocus works but seems a bit slower and louder. Right after I dropped it, it wouldn't autofocus at all. I don't know if there's anything I can do, or should do, or if I'm just complaining. It's a cheap lens but man that bums me out.
