Unreliable AF on 7D with FW 2.0.3?

[FirstL]

I found that the focus on mine had actually changed to zone focus, left side.  I've never used zone focus.  New battery and correcting focus setting corrected the issue.  That's the only thing I found wrong after the firmware upgrade.  Hope there's not any more lurking.  Next time I'm going to wait and see if there are issues before jumping in and upgrading.

Just to make sure everyone here followed the same procedure I did. The new battery trick...its not really a trick. That was actually explicitly listed as a REQUIREMENT in the instructions for flashing the firmware. Canon was fairly explicit about the fact that the firmware upgrade would not fully "kick in" until the camera was powered off and the battery removed for a little while.

If you flashed your 7D and have not yet powered it off and removed the battery, do so now. It is a required part of the upgrade procedure.

Did that, exactly as the update instructions said.

This issue frsutrated me so badly, as I had an essentially worthless body on my hands, that I started researching how to roll back the update.  In the process of finding out that such a manuever is essentially impossible for the consumer, I hooked the camera to my laptop and realized through EOS Utilities that I only had Firmware update 2.0.0.  With nothing better to do, I went ahead and installed 2.0.3 and it appears to have solved my problem.  Otherwise I had every symptom the OP was experiencing, to such a bad extent that I couldn't use the camera.  I've shot 120000+ images with the body, so to have it just go kaput after a firmware update is totally unacceptable and an obvious sign that the update was the clear culprit.  Canon needs to figure this one out in a big hurry.

You might try reinstalling the update and pray that solves the issue.

You can roll it back

You can roll it back

How?

DID you read up on few of my posts here,  On a PC its basically a bait and switch get the EOS util to think you giving it he current firmware say 2.03 and just before it loaded it rename and replace it with the old one renamed to the current firmware (some guy online had all the firmwares stock piled, so you could go back to any version you want)

if you have a PC i could guide you, MAC only im a bit lax on the file tricks

Been running 2.0.3 on my 7D ever since it came out and haven't seen any of the issues reported.

Might be your Body, my body purchased in Nov of 09 feels a DOT heavier and the buttons different than a friends purchased in 2011. Especially the back wheel has a heavier click.

Just wanted to let you all know I redid the firmware update twice (same procedure as the first time, followed Canons update instructions). The AF seems to be OK now..
This is really strange!
