Canon EOS-1DX lock up Err 80 code

There has been some online discussion about the Canon EOS-1DX locking up randomly and reporting Err 80 error code. I recently received mine and have been able to reproduce the problem repeatedly and consistently as follows:

I’ve set a bunch of custom settings and am not going to go through them all now, as I don’t feel they are the cause, rather, it’s related to the camera’s light meter. But, want to mention that I have disabled AF drive from the shutter release, so the fact the camera can’t shoot with either the lens cap on or pointed at something very dark, isn’t because it’s unable to lock focus. I strictly use the AF-ON button to activate focus, therefore, hitting only the shutter release should fire the camera every time.

Here’s what happened:

Some forum commenters believe it happens when spot metering and AF point is linked, so I turned on that custom function, put a lens cap on, closed the eyepiece shutter, played back a photo, hit the shutter release and the camera worked fine. I set the meter to spot metering (makes sense, no?), put the lens cap on, closed the eyepiece shutter, played back a photo, hit the shutter release and the camera locked up. The reason for covering both the lens with a cap and closing the eyepiece shutter is to simulate an environment with zero ambient light (one forum commenter complained about this happening while photographing stars)

Pulled battery and switched back to multi-segment metering – worked fine.

Turned off the spot metering linked to AF point feature, set metering to spot, played back some images and with cap on and eyepiece shutter closed, camera locked up every time I hit the shutter release to try to take photos. I’m not pushing the AF-ON button, so AF is inactive and not a factor.

AND, the exact same thing happened with partial metering selected.

With the cap on but the eyepiece shutter open, the camera will shoot, I guess because some ambient light in the room is getting through the eyepiece.

Sometimes the camera reports the Err 80 problem, but other times it just simply won’t shoot, but other functions remain. For example, AF will rack back and forth, but it won’t lock (only tried it in One Shot mode so far). I can enter live view, use live view AF (contrast detect based AF) to lock on a subject, shoot off as many frames as I want, exit live view, and the camera still will not release the shutter. The only solution is to pull the battery to reset the camera.

Then this happens, but only sometimes: with the eyepiece shutter open and cap off, the correct exposure in the scene is ISO 6400 1/30 f/1.2 and with spot or partial metering set, the camera’s continuous drive advance drops from maximum at that shutter speed to about 3fps. Point the spot meter area to where correct exposure is around 1/125 f/1.2 and it hits full fps. Recompose to where exposure is around 1/80 f/1.2 and fps drops back to 3fps. If I let the camera sit for 5 or so minutes (I have auto power off set for 4 minutes), then use it again, it will blaze away at full fps with the same settings that previously caused the fps drop.

Finally, the lock up problem DOES NOT happen with evaluative or average metering.

In conclusion: my suggestion is DO NOT use spot metering or partial metering in very low light situations if there is any chance the camera will be in a zero light environment, which is what seems to trigger the lock-up.

I plan to post a more in-depth impressions review once I’ve had the chance to use the camera in various situations. But other than this lock up bug, which honestly would never have been an issue for me because I never use spot or partial metering modes, the camera so far seems like a solid upgrade from the 1D Mark IV.
