<p>Hi there,<br> I fell on a rock today. My lens was in a lowepro lens trekker 600aw, so the impact was not so hard. After the fall, i look at it and see no sign of collision, the all thing seem tight (no movement anywhere) and everything seem normal.<br> But when i try to use it the lens doesnt respond at all. No autofocus and no manual focus !!!<br> <br />Somebody have a idea of what is going on ?</p> <p>Thanks to helping me on this really bad situation...</p> <p>Jacques</p>
