Well, I just got My Mark IV upgraded to the latest firmware 1.0.6 form 1.0.4 and I’ve noticed a serious problem. After extensive use on Sunday I can say camera will not focus the way it did before the upgrade…..not even close
We had three Mark IV on the deck yesterday shooting Bald Eagles, all three with the same lens (EF500 f/4) *, and all with new firmware. Camera will not focus fast enough, in most cases won’t even lock on the subject and most of the shots with achieved focus are out of focus…something is seriously wrong. There is always a possibility that all this could have been due to an “user error” but having three identical setups operated by three different guys I really doubt it.
Now I need to find somewhere the old firmware and put it back
* Just to clarify, there were three cameras 1D Mark IV and three Lenses EF 500 f/4

Just to make double-darn sure I'm reading/interpreting your sentence correctly ... you used "one" 500 f/4 on three bodies with upgraded firmware and wound up with unacceptable AF results, right? "If" my interpretation is correct why do you think the AF problem is due to three camera bodies (as versus the one lens)?
One more question ... are you talking about static, dynamic, or both types of targets, thanks?

Joe,
No, we used three bodies with upgraded firmware and "three" (not "one") lenses and the subjects were dynamic
Maybe before you send it back, you could try to reinstall the new firmware. Maybe there was an error in your download or the upload to your camera. Worth a shot as it will only take a minute or two.
I hesitate to post because I know that I'm inviting an attack for attempting to stop an internet panic. But I'll point out a few things anyway.
First, according to the report that I got from someone who was there with you guys is that there were two of you there who were saying that you had problems with the 1D Mark IV and the new firmware, not 3.
Next, my guess is that, throughout the country yesterday, there were people shooting NBA games, NHL games, and all kinds of sports and other action with their 1D Mark IVs and the new firmware, and I'd guess that, with the internet being what it is, there would already be a firestorm on the internet if there was a genuine problem with the firmware.
I'd also guess that, after going through the 1D Mark III ordeal, Canon would be testing any new firmware especially thoroughly before releasing it.
Additionally, my 1D Mark IV is focusing superbly with 1.0.6, and that includes servo action.
So, putting all of this together, I suggest that there is the possibility that something else is going on other than a problem with the firmware.
Yes keep us posted! I do shoot BIF and use AI Servo allot. Havenot shot since latest firmware upgrade though.
Good luck! Best send it in to be safe. It is under warranty and I know it is a royal pain, been there done that, but for $5k let them woryy.
Again, good luck and keeps us all posted!
