Canon has issued a couple of service advisories to notify customers of known issues with the 6D and 1D X DSLRs. The former camera has a YouTube problem, while the latter has some autofocus issues for certain customers.
First, the 6D bug. In a service notice released earlier today, Canon writes, “We have identified a phenomenon which prevents movie files shot using Canon EOS 6D Digital SLR Cameras from being played back on YouTube.”
If you’re desperate to share your 6D video clips through the Internet’s most popular video service, all is not lost. Canon has released a set of instructions for what you must do to make the files compatible.
Basically, you’ll need to load and re-save the movie file through ImageBrowser EX, a program that comes bundled with the 6D.
Now on to the 1D X issue. In a notice released this past Monday, Canon acknowledged that autofocusing isn’t functioning for lenses/extender combos with a max aperture of f/8:
Firmware Ver. 1.1.1 enabled the center AF point to autofocus when the camera is used with lens/extender combinations whose combined maximum aperture is f/8. On some of the cameras with firmware Ver. 1.1.1, auto-focusing does not function at f/8 aperture. *This phenomenon does not occur with a camera which firmware has been updated by a user, or by Canon service center.
The 1D X’s lack of autofocus at f/8 was a weakness of the camera that was first reported last year. In October of this year, Canon released a firmware update that brings AF to f/8. It seems that newer 1D X cameras are shipping with buggy versions of that new firmware.
You can figure out if your 1D X is one of the cameras described in the advisory by taking a look at the serial number. If the sixth digit from the left is a 4 or a 5 and you don’t have a white dot in your battery compartment, your camera is one of the affected ones.
The fix for this problem is easy though (there’s no need to take the camera to a service station): simply overwrite your camera’s Version 1.1.1 firmware with a new copy downloaded from the Canon website and you’ll be good to go.
Update: Canon has released firmware version 1.1.2 for the 6D that addresses the YouTube issue.
