With custom configuration, you can make it just one button (and thus half as sucky). Switch the joystick to be "AF point direct", then all you need to do is _either_ tap the shutter _or_ the AF point selector button. Yes, still sucky, but only 50% sucky.
I miss the ability to use the back dial to select among the 8 outer and one center points - was insanely fast and precise.
To Users of the EF200mm f/2L IS USM and EF800mm f/5.6L IS USM Lenses with the Canon EOS 5D Mark III Digital SLR Camera.
Thank you for using Canon products.
We have confirmed that when the EF200mm f/2L IS USM and some units of the EF800mm f/5.6L IS USM lenses are used with the Canon EOS 5D Mark III Digital SLR Camera, the Lenses may emit an abnormal noise.
The Canon EOS 5D Mark III Digital SLR Camera does not need to be repaired as a result of this phenomenon.
The support measures for this phenomenon have been decided and they are as described below.
Phenomenon
If either of the Lenses is attached to the camera with the Image Stabilizer switch on the Lenses set to ON, the Image Stabilizer will synchronize with the autofocusing (AF) function and an abnormal noise may occur. This abnormal noise does not affect captured images.
This phenomenon only occurs when the camera is used with either of the Lenses, and does not occur when the camera is used with other lenses.
Affected Products
EF200mm f/2L IS USM Lens
EF800mm f/5.6L IS USM Lens
*This phenomenon does not occur with cameras other than the EOS 5D Mark III.
*If the fifth and sixth digit of the six-digit alphanumeric number that is imprinted on the lens mount of the above EF lenses is of any of the following numbers, the lens is affected.
EF200mm f/2L IS USM： If the fifth and sixth digit is 00, 01, or 02.
EF800mm f/5.6L IS USM：If the fifth and sixth digit is 00, 01, 02, 03, 04, 05, or 06.
How to Identify Affected Products:
Please check the six-digit alphanumeric number as indicated in the image below.
Support
The Canon Lenses affected by this phenomenon will be inspected and repaired free of charge starting from May 21, 2012. If you own one of the affected lenses, please contact our Customer Support Center.

Although they will never share, I would love to know the technical specifics that explain the multiple variables at play, like why only the Mk3 and why only a certain range of each lens... I would also like to know what the phenomenon of "synchronizing" IS and AF really means.

Mentioned on another thread, but it sounds like an issue with the 4 stop IS system. Could have been a parts supplier during that time frame when manufactured or any number of things. The fact that the issue was isolated down to a specific time frame and related to the lenses versus the body tells us something at least. My guess is something electronic within the IS system.

Thanks for that, I knew this but forgot.
The link states:
"The next two numbers, "02", are meaningless in determining how old a Canon lens is. This is a Canon internal code (that is occasionally omitted)."
Clearly they are not meaningless numbers, likely a revision number by Canon. Now the recall makes more sense.
