t4i firmware bug

[hvirla]

My Rebel T4i often freezes in live view mode and I have to remove the battery to unlock it.

Is it a firmware problem?

Contact them by phone they will resolve yor issue. I had the exact same issue with my T4i and it was resolved after my camera was replaced. See thread here: http://forums.usa.canon.com/t5/EOS-Rebel/T4i-camera-completely-locking-up-in-the-ON-position/m-p/728...

Hi everyone,

We have an update on this topic.  New EOS Rebel T4i firmware has just been released.  Firmware Version 1.0.4 offers performance improvements when shooting with certain lens models equipped with a stepping motor.  To learn more and download the update, click here.

Thank you.

I'm more than happy to deal with Canon. T4i is a fantastic camera and with the 1.0.4 update, there is not any crashing at all

After an intensive testing all day long with video, can say the bug was solved.

Canon for ever.

I'm having this exact issue on my brand new (a day old) T5i with 18-135 STM.  I'm returning it to the online store for a replacement... Very disapointed!

What is the firmware version on your T5i?

1.1.1

[bobakman]

Yep 1.1.1 same as mine. I just wanted to make sure that there was no difference. My T5i is about 3 months old and so far it has not had the same issue that my T4i did then again it was 3 months out that my T4i started having the issue. Sorry to hear that yours has but returning it is the right thing to do.

I took my camera and stm lens to canon's service and repair. It turned out that there wasn't anything wronge with the camera itself but there was something wronge with the lens. Canon stated they made "electrical adjustments" to the lens board and that seemed to fix this issue. Haven't had a problem since.

Was your camera a T5i?  I'm leaning towards this being the problem on mine as well only because when I put the 55-250mm IS II on it's not crashing, even though this lens is quite stubborn on auto focus, and noisy!  I'm likely going to return the whole thing to the store and let them provide a replacement since I've only had it for a couple of days.  But, if it's just the lens I may ask for an advance replacement to see if that does the trick instead 🙂  Thanks!

I have the t4i with 18/135 STM kit. I know there's a firmware update for this issue but I can't say if it works or not. After canon repaired my lens it worked fine. A week later I did the firmware update and it worked same. You should definitely get your lens looked at. It should be under the warranty if you had it less than a year I think. I turned my camera in Friday and got it back Tuesday working as designed without any problems.
