5D MKIII stutter speed fault


Cherish Photography:
My camera has just developed a fault.  From time-to-time it won't allow me to change the shutter speed with the main dial.  I have to disconnect the battery and turn back on to fix the fault.  This is while in manual mode.

Very strange.  Anyone else had this fault?

Never ... unless I've accidentally activated the multi-function lock!

Cherish Photography:
Thanks.  The multi-function lock hasn't been locked.  Just checked and I don't have the latest firmware, so I'll update that and hopefully the problem doesn't happen again.

Never had a prob like that. If the firmware doesn't fix it then I'm afraid the camera may need to go back to Canon.
