A workaround for the Canon EOS 1D X AFMA Bug
has been reported.
From the Canon EOS 1D X AFMA Bug forum thread
John, try this - Enter an AFMA for an older lens (one without the serial number on the chip, like the 70-200 II), then power off the camera. Turn it back on, and the AFMA menu should show zero and the serial number will be zeroed out (though if you take a photo I'm willing to bet it will still show the adjustment you made). Now without powering off the camera, remove the lens and put it back on (or at least turn it enough so the contacts aren't touching). Go back into the AFMA menu. I'm willing to bet you'll see your adjustment value and the serial number. John:
Trowski, you are a genius! It's kludgy, but it's a workaround. After doing so, it seems to persist for one power cycle, too. After doing that with my 70-200 II, I put on my 40/2.8, and it showed the previously set -2 straight off. Power cycling then zeroed it out again, but just loosening and remounting the lens with the power on brought the correct -2 back. Also, changing the AFMA then doing the workaround results in the new AFMA being applied, and restored after a repeat of the workaround, as long as you change the AFMA setting right after the lens unmount/remount, when the previous setting is visible.
Some (including Bryan, now) have reported this issue, others say they don't have the problem. Personally, I always power off the camera before changing lenses - I wonder ... if I routinely changed lenses with the camera powered on, would I not have noticed the issue? As stated above, the value seems to be saved, and recorded in the EXIF, just not displayed on-camera until it's forced to re-recognize the lens.

From Think Tank Photo:
We believe that the best advertisement for our camera bags is ... our camera bags. Once photographers actually feel their construction, the quality of the designs and materials, they realize how seriously we take our mission of being the premier developer of camera bags for the professional and serious photographer.
To aid you in figuring out which of our bags are right for you, periodically we roll out what we call a "Test Drive." With this program you can order and use the Test Drive gear for free for 30 days. If it meets your standards, you pay for it at the end of the trial period. If not, send it back and you won't be charged.
We are rolling out a test drive for our highly-regarded Sling-O-Matic sling bags.
Starting on Monday, July 16th, you can try a Sling-O-Matic™
for free for 30 days! If you don't want to keep it, ship it back to us, no problem. If it meets your needs, on the 30th day your credit card will be charged. (Offer limited to U.S. addresses.) Check out the product video.
With our Sling-O-Matic™ line-up of bags you have the photo industry's first sling bag that can be easily switched back and forth to either shoulder. The Sling-O-Matic's adjustable, fully padded shoulder strap "automatically" slides along a set of rails to change which shoulder the bag can be worn on.
This innovation is the solution to the problem inherent with sling bags: they are designed to be to worn over one shoulder only. With one smooth motion, the Sling-O-Matic can be quickly switched to the opposite shoulder without losing the characteristics that have made sling bags popular among photographers.
The Sling-O-Matic series offers three unique bags to choose from, depending on the photo gear you carry. The Sling-O-Matic 10 can carry a standard-size DSLR and three to four lenses, including a 70-200 f2.8. The Sling-O-Matic 20 and Sling-O-Matic 30 can each carry a standard-size DSLR and four to six lenses, including a 70-200 f2.8. The Sling-O-Matic 30 also features a separate laptop compartment for carrying a 15.4" laptop Key Features:
- Industry's first sling bag that can be easily switched back and forth to either shoulder.
- Each bag fits a DSLR with up to a 70-200 f2.8 lens with lens hood in position.
- All bags are flexible to fit standard size DSLRs with a lens attached.
- Discreetly stylized to avoid obviously appearing like a camera bag.
- Long side pocket for carrying a tripod, large water bottle, or other accessories.
- Large handles on three sides.
- Wide zippered pockets on front, back, and side.
- Business card pocket for identification.
- Removable/adjustable straps and waist belt for additional stability.

Friend NeuroAnatomist (AKA John) has pointed out
a Canon EOS 1D X
Autofocus MicroAdjustment bug:
"In the AFMA menu, when When Adjust by Lens is selected, powering off then on resets the setting (or W/T settings for a zoom lens) to zero, and also clears out a manually entered lens serial number. If I set it to All by Same Amount, the setting entered is retained...but, powering off actually changes the setting to Adjust by Lens, which is zeroed out. Even setting it to Disable and power cycling results in it being set to Adjust by Lens."
"The same reversions occur if the camera goes into standby mode - when it's woken up, the AFMA setting, regardless of where it was left, reverts to Adjust by Lens with the previously set value(s) zeroed out."
I have verified the issue with my 1D X. Expect a firmware update to resolve this bug.
