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.
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.
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)
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.
We’re told from a new source what Canon plans to do for NAB 2014 next month. We’re told that two new cameras are planned for the announcement, at least one being in the Cinema EOS line. It’ll have CFast 2.0 and be PL mount. There were no other specs mentioned. The second being unknown at this time.
Another announcement will be a major firmware update for the EOS-1D C camera. New features can be expected, as well as matching all the features currently in the EOS-1D X.
More to come…
Another mention of a hybrid viewfinder coming to a “high end” Canon DSLR is making the rounds.
Basically, the viewfinder is both electronic and optical. The electronic viewfinder would take over for video recording and the optical viewfinder would be used for stills.
I see this as a possibility in one of two cameras initially. Either a replacement to the EOS-1D C or in the EOS 7D Mark II (could be named something else). We’ve been told in the past that the EOS 7D replacement would receive a host of video features to help differentiate the camera from the EOS 70D and everyone else currently making a high end APS-C DSLR.
I think whatever replaces the EOS 7D will definitely have some new technology in it, just like the 7D did when it arrived on the scene 4.5 years ago.
More to come…
Hybrid EVF Coming to EOS?
There is a new rumor floating around about the next high end, and high megapixel camera from Canon. Apparently this camera will have a hybrid EVF, optical for stills and electronic for video purposes. Megapixel count is said to be 35mp or higher, though the exact number isn’t known.
The moniker for the camera? The EOS-A1, though it’s unknown if that’s just the prototype name.
I’m sure there will be a time when Canon starts to experiment with different solutions for the viewfinder in cameras. If the above technology is an actual thing Canon is testing, I’d expect to see it in a Cinema EOS DSLR first. Perhaps such a feature that could differentiate it from its standard EOS cousin? Speaking of which, we have been told to expect a new Cinema EOS DSLR in 2014, and most likely at NAB in “development” form.
A grain of salt on this one, this is a rumor from another web site.
Two new full frame cameras coming?
We see talk of two new full frame cameras coming in 2014 with availability in the early part of 2015. It’s mentioned that the EOS 5D Mark III would move up the spec ladder once again, but wouldn’t be the camera for “total image quality”. That would be saved for studio based EOS-1 body that is coming next year.
There is no chance of an EOS-3D according to this report. Although medium format is “still an option”. This information apparently comes from a higher end dealer presentation that occurred in Japan.
This is the first mention we’ve seen for an EOS 5D Mark IV. If two new full frame cameras are on the horizon and one is an EOS-1DXs type of body, what could the other one be? I’m willing to wager the EOS 6D won’t be replaced before the EOS 5D Mark III or EOS-1D X.
I assume he above report doesn’t consider the Cinema EOS branded EOS-1D C as one of the “full frame” cameras.
From the interview with Mr Onda
Reading a bit between the lines during the interview with Dan Chung and Mr Onda, it appears a few new things are coming to the Cinema EOS line and probably to EOS DSLRs as well.
The first being CFast 2.0, a version of Compact Flash announced back in 2008. SanDisk currently makes CFast cards that are capable of writing at 350MB/s. These cards will be needed to record 4K RAW video. It sounds like Canon will be moving towards CFast in their next Cinema EOS cameras, and perhaps DSLRs as well.
Secondly, it seems there’s a possibility of a full frame Cinema EOS camcorder coming down the pipeline. While you can currently get full frame 4K recording (16:9 crop from the full frame sensor) with the EOS-1D C, the C100, C300 and C500 are Super35 sensor cameras.
TOKYO, Japan, November 12, 2013 — Canon Inc. today announced that the EOS-1D C digital SLR camera, part of the company’s Cinema EOS System lineup of digital cinematography products, has been independently tested in accordance with European Broadcasting Union (EBU)1 standards for HD content acquisition.2 The tests found that the EOS-1D C is the first digital SLR camera to satisfy the stringent testing criteria for HD production.
Results indicated that the EOS-1D C provides “exceptional” HD resolution from a 4K source with “very low” aliasing, and “good” color performance and motion portrayal. The test results also confirmed that the EOS-1D C camera system and its imaging performance comply with the recommended specification for inclusion in HD Tier 1 for HD production.3
A new free-of-charge firmware update for the EOS-1D C to be made available on November 12 will enable the camera to correct for insufficient peripheral illumination when outfitted with supporting EF Cinema Lenses4 and make possible audio line input.
Additionally, an enhanced version of the EOS-1D C’s dedicated EOS MOVIE Utility software for Macintosh5 and Windows,6 scheduled to be made available free of charge in late December, adds a Mac-version video playback function and the ability to capture consecutive still images from a video file.
Canon will continue striving to enhance the functionality of its Cinema EOS System, contributing to further expanding the realm of visual expression and the development of cinematic culture.

Canon Firmware Upgrades for the EOS-1D X and EOS-1D C Digital SLR Cameras Deliver Improved Creative Control and Convenience
Firmware Version 2 for the EOS-1D X is Based on Extensive User Input and Provides More Efficient Autofocus Performance in Low Light, Custom Controls, and Improved User-Programmed Functionality
MELVILLE, N.Y., October 22, 2013 – Canon U.S.A., Inc., a leader in digital imaging solutions, announces improvements in the functionality and convenient operation of the EOS-1D X Digital SLR camera and the EOS-1D C Digital SLR Cinema camera through new firmware scheduled to be available starting in January 2014 and November 2013, respectively. Firmware enhancements for the EOS-1D X Digital SLR camera are designed to provide photographers with greater creative freedom and speed, especially in sectors such as sports, wedding, nature/wildlife, and journalism, which often contain rapidly changing action, sometimes in low-light environments. Service enhancements for the EOS-1D C Digital SLR Cinema camera improve lens performance, lens status display, metadata storage, and audio recording.
“Canon constantly strives to provide our customers with advanced and innovative technology in our products,” noted Yuichi Ishizuka, executive vice president and general manager, Imaging Technologies & Communications Group, Canon U.S.A. “We understand the daily life of photographers, we listen closely to what they have to say, and we use their feedback in our constant efforts to improve existing products and develop new ones. The latest Canon firmware for the flagship EOS-1D X Digital SLR camera provides better automation to help photographers fine-tune how the camera operates moment-by-moment so users can concentrate on creativity and success. Filmmakers have also requested improved functionality for the EOS-1D C Digital SLR Cinema camera, and its new update delivers.”
Improved Operability for the EOS-1D X
Developed as the ultimate Canon EOS camera, the EOS-1D X Digital SLR is designed with foresight that enables its performance to be periodically improved with new firmware upgrades, helping to ensure maximum long-term value for owners and users of the camera. These improvements are engineered to support and advance the evolving creative needs and business imperatives of professional photographers and committed high-end amateurs. The features provided by firmware version 2 are designed for more efficient automation that takes the task of changing settings away from the “heat of the moment” and enables photographers to concentrate on creativity and obtaining valuable shots. Firmware version 2 upgrades and operability additions include a total of 10 features that are now new or improved:
AF Performance with Moving Subjects – For greater creative control, additional parameters have been added to AI Servo 2nd Image Priority, enabling users to adjust these settings for more accurate AF performance according to the situation at hand. Photographers can fine-tune the balance between prioritizing focus versus the framing rate for the second and subsequent shots in a burst.
Enhanced AI Servo AF Performance in Low Light Conditions – The AI Servo focusing algorithm has been improved to allow more time for light sampling during AF activation prior to shutter release, enhancing AF performance in low-light situations. Additionally, initial AF control is now based on the new “+2 focus priority” setting of AI Servo 2nd Image Priority, which has higher distance measurement capabilities under low-light conditions. Upon full depression of the shutter button, settings from AI Servo 1st Image Priority take over and then settings from AI Servo 2nd Image Priority are applied on any subsequent images in the burst. This increases the probability that the first image in a burst sequence will be as sharp as possible.
Improved Acceleration/Deceleration Tracking Parameters – To improve tracking performance of fast-moving subjects that fill the frame, additional parameters for acceleration/deceleration tracking in AI Servo AF have been added to provide photographers with more precise control when photographing rapidly moving subjects that accelerate or decelerate quickly or unexpectedly. In response to feedback from professional photographers, these new settings have been added to handle larger differences in speed (i.e., the rate of change in image magnification) compared to the previous firmware.
Selection of Initial AF Point While Shooting in 61-Point Auto Selection AF – This new option in the AF Menu provides more continuity when switching to 61-Point Auto Selection AF from any other AF Point Selection mode. The option maintains the AF point selected from the previous Selection mode as a starting point for 61-Point Auto Selection AF. It also maintains the ability to change to a pre-programmed AF point when changing the Selection mode. This time-saving option is designed to help eliminate the need to stop and think, and helps photographers to customize their individual shooting style.
AF Point Switching According to Camera Orientation – In addition to programming the EOS-1D X camera to automatically switch to a different AF point and area selection mode based on camera orientation, firmware version 2 adds the option of programming only the AF point according to camera orientation (horizontal, grip up and grip down). This new ability to select up to three different AF points according to camera orientation allows for greater customization of the camera to specific shooting styles.
Expanded Minimum Shutter Speed in Auto ISO – In response to user feedback, this improved functionality in Auto ISO enables photographers to select a minimum shutter speed as high as 1/8000th of a second to freeze moving subjects.
Exposure Compensation in Auto ISO with Manual Mode Set – This new function enables photographers to manually set a desired shutter speed and aperture, use Auto ISO to control the exposure, and use Exposure Compensation to adjust the exposure for challenging lighting conditions (e.g., a very dark or very bright background). This new function can be activated through the Quick Control Dial or by using the Main Dial while pressing the SET button.
Toggling Between Alternate Camera Settings – EOS-1D X camera users can now toggle between three groups of camera settings instantly by pressing the shutter button, AE Lock button [*] or the AF-ON button. Selectable settings that can now be assigned to the AE Lock and AF-ON buttons via Custom Controls include:
- Currently selected AF point vs. pre-registered AF point
- AI Servo AF configuration sets (Case 1 through Case 6)
- One-Shot AF vs. AI Servo AF
- Currently selected drive mode vs. 14 fps Super High Speed drive mode
With these new options, photographers can reconfigure their EOS-1D X camera on the fly, while keeping their eye on the viewfinder to maintain concentration on the shot they are trying to get. For example, the camera could be set up for One-Shot AF and single shot drive mode on the shutter button, AI Servo AF in Case 1 with high-speed continuous drive mode on the AE Lock button, and AI Servo AF in Case 4 with super-high-speed 14 fps continuous drive mode on the AF-ON button.
Same Exposure for New Aperture in Manual Mode – This new firmware feature provides users with the ability to maintain consistent exposure levels in Manual mode when the aperture changes, for example when a photographer shoots at maximum aperture with a variable-aperture lens (such as the Canon EF 70-300mm f/4-5.6L IS USM telephoto zoom) or when using a lens equipped with built-in extender (such as the EF 200-400mm f/4L IS USM Extender 1.4X). The feature gives users the option to have the camera adjust the shutter speed or the ISO to compensate for the aperture change.
Display Protected Images Only – Users can now page through protected images only via an option on the main dial. This feature already exists with rated images, and is an expansion of that capability.
Enhancements for the EOS-1D C
A versatile, self-contained 4K cinema camera as well as a robust still photography camera, the Canon EOS-1D C will also benefit from a new service update that further enhances the performance of this unique imaging device.
EF Lens Communication – The new service update for the EOS-1D C Digital SLR Cinema camera will enable Canon EF-mount Cinema lenses to store lens metadata in the video recorded by the camera. Furthermore, Canon EF-mount Cinema lenses will be supported by Peripheral Illumination and Chromatic Aberration Correction functions, helping to improve overall image quality .
Audio Recording – In response to user requests, audio on the EOS-1D C camera has also been enhanced. Currently audio recording is limited to a MIC input, but the forthcoming service update will permit selection of LINE or MIC input, allowing use of a wider variety of external audio sources.
New Firmware Release Schedules and Installation Procedures
Firmware version 2 for the EOS-1D X Digital SLR camera is scheduled to be posted on the Canon U.S.A. website in January 2014. Users will be able to download and install the new firmware on their own, or have it installed by an authorized Canon Factory Service Center. For more information please visit: www.usa.canon.com/eos1dxfirmware.
The update for the Canon EOS-1D C Digital SLR Cinema camera is scheduled to be available November 2013, and will be installed at no charge as a service upgrade that requires the camera to be sent to an authorized Canon Factory Service Center. For more information please visit: www.usa.canon.com/CinemaEOSFirmwareUpdate.
A new firmware update is available for the EOS-1D C. Firmware Version 1.3.x adds new functionality incorporating the following features and modifications:
Lens aberration correction with EF Cinema Lenses: Communication between Canon EF Cinema lenses and Canon cameras has had a few effects on the operation of the EOS-1D C. The following features are now available as menu options:
- Peripheral Illumination Correction: This feature maintains even brightness from corner to corner of an image. This will virtually eliminate vignetting and any other unevenness of light across the image.
- Chromatic Aberration Correction: This feature reduces color fringing in areas of an image with high contrast color. It reduces color bleeding, which is easily noticeable at edges and degrades perceived image quality.
- In addition, communication between the lens and camera body will allow the F-stop to now be seen on the viewfinder. Focus position and F-stop will also now be recorded by the camera.
- Flicker caused by manual aperture adjustment has been reduced with this update, this could cause slight underexposure which may result in exposure compensation in some cases.
Sound recording with Line input:
- After requests from users in the field, audio recording through a mini plug (3.5mm) connected to the external microphone terminal is now supported. This will allow for the recording of audio sources other than microphones, such as mobile devices or audio players. The standard input level is -8 dBV and can reach an input signal of up to +6 dBV. Sound recording levels are adjustable at 64 sound-recording levels.
Service support start date is anticipated mid-October 2013. For information regarding the EOS-1D C firmware update (which must be performed by a Canon Factory Service center) please contact Canon Cinema EOS Support at 1-855-CINE-EOS (246-3367).
