Just a quick post to say I found an issue with the 1DX Mark2 and EF 200mm f/2.0.
1DX2 is running the latest firmware (1.1.2), this issue has nothing to do with the 200/2's IS - 5D3 problem, and my lens is not one that was effected.
Seems that when the camera is powered down and the 200/2 is mounted it fails to power up when switched back on.
The only way to restore it is to pull the battery, then all is normal, out of 10 attempts its normally fails 8/9 times.
CPS have replicated the problem with their 1DX2 and 200/2 and have forwarded it to Canon, I hope they sort it soon!
