Están reportando problemas de AF con las 1Dc / 1Dx anteriores a las fabricadas al 24 de enero de este año. El problema ha sido detectado en las 1DC, aunque la 1Dx lleva la misma mecánica, así que posiblemente pueda estar también afectadas. Parece ser que a temperaturas extremadamente bajas no enfoca (por debajo de -10º/-15ºC o más). Fuera de esas temperaturas extremadamente bajas en alta montaña, la cámara funciona sin problemas.
Según Canon Rumors (http://www.canonrumors.com/2014/04/eos-1d-x-eos-1d-c-cold-weather-autofocus-issues/), el problema (comentado por una fuente posiblemente cercana al SAT de Canon aunque no reconocida como oficial), se debe al sistema de bloqueo del subespejo. Os pongo a continuación lo que ponen en la web de Canon Rumors, por si alguno ha notado el problema:
Symptom:
Camera “does not autofocus”, “does not search in AF”, or “does not focus in AF search” depending on the reporter or the camera settings; specifically, the focus cannot be achieved in low temperatures (under 0 degree Celsius).
* Although there has been no reported occurrence on the EOS-1D C, the mechanical structure of the Mirror Box Ass’y is the same as the EOS-1DX, so the EOS-1D C is included in the affected product.
Cause:
This phenomenon is due to the Locking Claw of the Sub Mirror (mirror for AF) going over the Locking Pin. The Sub Mirror’s angle becomes deviated and the light rays for AF does not fall on the AF sensors, causing the “does not autofocus” phenomenon.

Service of Affected Product:
To control the torque, the process to check the Locking Claw’s going over torque of Locking Pin has been newly incorporated. (From production on January 24)
Repair Procedure:
Handling of units in question: If the user complains about this specific phenomenon (does not autofocus in low temperature), replace the Mirror Box Ass’y with the ones to be shipped in the future (CY3-1661-010 or CY3-1687-010).
Handling of general repairs: If the user does not mention this phenomenon, please handle as normal repair.
En otras palabras ... que si alguien tiene ese problema, esta nota indica con precisión que esa parte mecánica de bloqueo del sub-espejo debe de ser cambiada en el SAT de Canon por una de las de nueva fabricación.
