We thought the same about the 200mm f/1.8L
As for used prices, having been in this market a lot recently I can tell you tat used prices have dropped considerably across the entire line up. The old adage that "you only rent L lenses" ( ie: resale prices are 10% lower than new) is not so true anymore.

) when mounting the 200L/2 on the 1DX2? Mine causes my 1DX2 not to power back up when switched on sometimes after mounting, remove the battery and it's all good again? Latest firmware 1.1.2 and new 1DX2 batteries, I have passed it to CPS who are going to test the combo today for me and let me know, hope I don't have to send them in, never had an issue with my 200L/2 before.
I did send the lens back for the upgrade/update when I bought it used and it was making sounds on my 5D3. I don't know if it's a related issue or not. But I'll wait to see what you report back first.
