First the bad news:
A few years ago I had a 1D MkIIn with 70-200 f/2.8is fall from hip height onto carpet. Worst case scenario. The body was a write off and the lens needed expensive repairs at CPS. Afterwards, that lens was never quite right. OK, but the snap just wasn't there any more. Traded up to the 70-200 f/2.8isII which I still have.
Now the good news:
Under my insurance policy, I was surprised that it covered me for "At Fault" accidental damage. A small excess was paid, they dealt with CPS, CPS loaned me replacements for the lens repair period. The Mk2n is landfill.
