<p>Thanks, everyone, for the sympathy and good wishes. And thank you, Shun for the links and reminder that things may not be as bad as they first appeared.</p>
<p>When the accident happened, I was so disgusted that I just picked up the pieces and shut them away in the camera bag without looking too closely. Out of sight, out of mind. Today I finally decided to have a look. It seems the lens did break cleanly at the mount. Apart from that, there's no sign of external damage to the lens assembly, the lens shade, or the camera, and the camera seems to work just fine.</p>
<p>So maybe this will need only the simple 15-minute repair job Bjorn describes in the first thread cited above. (Even so, it will probably cost more than the 25¢ and bottle of beer my grandfather used to pay for handyman work. ;<) )</p>
