We have been notified about a known issue within Canon on the Canon EOS-1D X and Canon EOS-1D C camera bodies and sometimes not autofocusing in cold weather situations. I have read about the issues on our own forum as well as on others.
Below is an explanation of the issue we’ve received from an anonymous source, though no official service advisory has been issued by Canon.
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.
EOS-1D X Mirrorbox Phenomenon in Cold Weather | Pre January 2013
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.
The line directly above is of great concern to me. If you bought one of the earlier EOS-1D X cameras and live in a warm climate, you may never know the issues existed until you went to shoot in a cold climate.
The notice is dated January 2013, so I assume all cameras manufactured after that date would be unaffected. There is no serial number range that I can see, nor do we know how widespread the issue is. However, if you have experienced this phenomenon, you now know what it is.
My immediate first impressions are quite good, amazing build quality, great zoom ring and the silly test shots looks terrific. I’ll be shooting exclusively with the EOS 6D on this trip.
Justin has received the Sigma 120-300 f/2.8 DG OS for review and he’ll be putting it through the paces with the EOS-1D X. He’s already shocked at the size and weight of the lens. No, it’s not a “hand holding” lens for most people. The first 2 negatives you can give the lens is the heavy and unnecessary metal lens hood and the equally enormous tripod foot. Third party accessory makers could surely knock a pound off the lens replacing both parts with lighter weight materials.
Optically and AF wise the lens is very good with initial test shots, Justin has the USB dock and will also put that through its paces.
Both reviews should be online some time in April, though I’ll be posting images from the Zeiss 15mm as the trip progresses.
Camera Canada is selling super telephoto lenses at a big discount over their US counterparts and ship to the USA. These items 100% qualify for USA warranty. I buy most of my gear in Canada from these guys. They’re great to deal with. The current currency difference between Canada and the USA should help offset the price of shipping. Camera Canada ships Canada Post/USPS to the USA and so far that has avoided any customs or duties for US customers.
Nikon has officially announced the D4S flagship camera body. There have been a lot of performance boosts as compared to the D4, such as a “newly designed” 16.2mp sensor, a new EXPEED processor, the ability to get to ISO 409600. There have also been tweaks to video, workflow and autofocus settings, though the AF system has remained the same.

EOS-1D X Replacement? Not this year, though I wouldn’t be surprised to see an EOS-1D C replacement. I think the EOS-1D X is still a world class capable body and Canon should be in no rush to replace it. Most people I talk to don’t want incremental updates, such as the perception with D4 to the D4S (again, image quality may change that opinion). The EOS-1D X should remain current well into 2015.
With Nikon officially announcing the D4S next week, we’re starting to see the usually unreliable mentions of Canon following suit with an announcement of their own. The latest being that Canon will announce a high end full frame DSLR some time in March.
We do not believe a camera above or replacing the EOS-1D X is on the immediate horizon, as we’ve seen a few small marketing campaigns for Canon’s flagship camera. Along with a feature adding firmware update that came out in January.
We’ve been told by a great source that Canon would announce 3 DSLRs in 2014. The first being the entry level DSLR that was announced last week. The replacement to the EOS 7D Mark II and a third camera that is currently unknown. There is always a chance of adding to the number of cameras in the way of a “development” announcement, but those are always hard to predict.
As always, whenever Nikon does something, there’s always an upturn of Canon speculation.
NAB is coming in April, so I would think Cinema EOS would get an announcement before the EOS line.
Long time Nikon shooter, author and Adobe professional Scott Kelby switched over to Canon about 6 months. Being that he’s a popular guy in the photography world, I assume he was being asked every 10 minutes why he switched.
The switch was made to a EOS-1D X and EOS 5D Mark III for the big reasons of ergonomics, menu system and skin tones.
Kelby sits down with Canon Explorer of Light Rick Sammon to discuss the switch to Canon.
I’m not sure how much Mr Kelby paid for the Canon gear he now has, but I hypothesize it was at a discount. :)
System switching is an odd thing to me, and always has been. Unless there’s a definitive feature or lens that one doesn’t have and the other does.
I have heard of Canon shooters moving to Nikon if they use Speedlites a lot, as Nikon’s ETTL does a better and more consistent job than Canon’s system does. When I hear a Nikon user switching to Canon, it seems to usually be about video features. I also know of a couple of nature photographers that moved over to Canon around the time the new big white lenses made it to market. They found great value in the weight savings of Canon’s new super telephoto lenses.
Switching for ergonomics is a weird one to me. After a few months with a camera, you’re used to it and it becomes second nature. I personally fumble around with Nikon’s pro bodies, but that’s because I have been shooting Canon predominantly for a long time. Had I always shot Nikon, I’m sure the opposite would be true.
