Our rumors were true, the Canon EOS-1D X Mark III remains at 20.1mp which is pretty much like its predecessor. The EOS-1D X Mark III is also capable of recording about 5.4K RAW internal video. This is great to see, as we were told that 5.9K was still on the table, so this confirms that minus a few pixels (Yes, I could have just done the math).

For those wondering about crop factor in video, there will be no crop in 4K or RAW.

It looks like an official announcement will be early next week.

  • 20.1mp
  • 16fps Mechanical
  • 20fps in Liveview
  • ISO 100-102,400 (extends up to 819,200)

Need for Speed
The Canon EOS-1D X Mark III will be blisteringly fast – offering exceptional precision, reliability, high-performance autofocus, and subject tracking – providing photographers with a tool that will help to capture the shot they are chasing. The camera's new autofocus algorithm will improve stability and tracking when using both the Optical Viewfinder and in Live View shooting mode, using Deep Learning Technology and adapting to help facilitate accurate focus tracking for every shot. When using the optical viewfinder the camera will use a new autofocus sensor, with approximately 28 times the resolution in the center of the EOS-1D X Mark II. Offering the ability to autofocus in even brighter and darker situations than before and with greater precision, the camera will have a range of autofocus capabilities, which will enable the photographer to get their shot. In Live View mode, users will be able to make use of 525 AF areas using the Dual Pixel CMOS AF system will cover approximately 90×100 percent of the image sensor. The camera will support significantly faster frame rates with full AF and AE, using either the optical viewfinder (up to approximately 16 fps mechanical shutter) or Live View (up to approximately 20 fps mechanical or electronic shutter). Additionally, the camera's dual CFexpress card slots will enable more than five times the RAW burst depth of its predecessor.

Powered to Dominate
The development of EOS-1D X Mark III is a clear example of Canon's commitment to pushing the boundaries of innovative imaging products featuring optically excellent technology. The camera will support an all-new, Canon-developed, CMOS sensor and DIGIC processor, that will deliver greater image quality, at even higher ISOs, with the ability to capture stills in 10-bit using the HEIF (High-Efficiency Image File) file format. HEIF produces wider dynamic range and greater color representation compared to JPEG. The power of 4K resolution brings stories to life – shoot 4K videos including 4K60p with 10-bit 4:2:2 Canon Log internal recording.

Conveniently Connected
For professionals, content delivery is just as important as image capture – the EOS-1D X Mark III will make it easy, featuring built-in Wi-Fi and Bluetooth low-energy connectivity in addition to GPS technology. To keep pace with ever-shortening deadlines, the camera will transfer data at more than twice the speed of the EOS-1D X Mark II when using the built-in Ethernet connection, or the new optional wireless file transmitter – the WFT-E9, which is also compatible with Canon's recently launched Cinema EOS C500 Mark II camera. Coupled with simpler network set-up the camera will greatly enhance the professional workflow

A Familiar Feel with Improved Attributes
Existing EOS-1D series users will be familiar and comfortable handling the EOS-1D X Mark III allowing seamless navigation with trusted ergonomics – whilst the magnesium alloy body will offer the durability expected from Canon's EOS-1D cameras. Professional photographers can trust the same impressive build-quality as the EOS-1D X Mark II – with phenomenal weather-sealing, standing up to harsh conditions, including wind, rain, and humidity. With incredible low-light shooting capabilities, the camera will now feature select illuminated buttons that allow for precision operation in challenging, dark and dimly lit conditions. The camera will also offer a new additional control for selecting AF points, built into the AF-ON button, allowing photographers to change AF points on-the-fly for the best composition – further helping to simplify their work. In addition, dramatically improved battery life – with the same LP-E19 – will allow professionals to shoot for longer periods of time, without having to change batteries, helping reduce the chance of missing a shot.

A new era in autofocus speed and accuracy
The EOS-1D X Mark III will feature a brand-new AF sensor with 28x more resolution than its predecessor, using advanced AF algorithms with deep learning technology for incredible focus tracking in any situation. And in Live View and video, there will be the added advantage of Dual Pixel CMOS AF across approximately 90×100 percent of the sensor with 525 AF areas. With AF over a wider EV range focusing with an EOS DSLR truly will never have been more accurate and versatile.

Outstanding stills and video
With a new Canon CMOS sensor and powerful new DIGIC processing, image quality even at high ISO will be taken to even greater levels along with 4K video at 60p, plus the options of capturing RAW video or 10-bit 4:2:2 video with Canon Log, both recorded internally to CFexpress cards. A new bright viewfinder will help connect you to your subject in real time.

High-speed camera communications
Delivering captured content quickly is the vital next step for a professional. This is why the EOS-1D X Mark III will feature Wi-Fi and Bluetooth low energy connectivity and GPS capability for seamless communication. With double the transfer speeds of the EOS-1D X Mark II, via the built-in Ethernet port or through the optional WFT-E9, and with a revised user interface for simpler and more intuitive operation, the new EOS-1D X Mark III will be designed to get the job done faster than any EOS ever before.

Always ready to perform, whatever the situation
The EOS-1D X Mark III will be radically upgraded for superb performance. Not only will it offer a blistering frame rate with the optical viewfinder including AE and focus tracking, but also dramatic improvements in Live View mode with the same level of accuracy, plus the ability to shoot using an electronic shutter. The camera will be engineered to excel in all areas, with dramatically improved battery life using the LP-E19 battery, new illuminating buttons and an all-new AF point selection control within the AF-ON button in addition to the multi-controller. All in a magnesium alloy weather-sealed body.

  1. Is the first spec list not just literally the 1Dx mark II specs? The list with 20 megapixels even says Cfast 2.0 and 16 fps, and the mark III definitely uses CF Express. Also says no log recording. I cant find anything in the first "leaked" list that isn't from the 1DX mark II. The other spec list that says pixels not specified looks much more accurate.

    Edit: as Pekr also just pointed out, Dual Digic 6+ is also the same as 1Dx mark II.
  2. They are just posting anything again without verifying anything just to get more views.

    Those are not the real specs, except the few that are on the end which were already presented with the development announcement.

    People are already out shooting with the production version of the camera, so it is not that far off.
  3. As others above, this deffo isn't the correct final spec. I can imagine retailers etc preparing the product page, creating a copy of the older model and editing from there in readiness. You want the page up and indexed by Google, even if final detail isn't ready for public view.
  4. Hmmm.... I do not think Canon would dare to make such an mini-evolution of their flag-ship. Not in an Olymic year in Japan. Alkso keep in mind the 24MP of the A9....
    Cannot believe this are the final specs.
    Where do they have these specs? Maybe someone wrot older specs into "specs sheets" as an placeholder

  5. I am surprised they are using dual digic6 processors. You would think after 4 years they could have done a bit better. I suspect this may contain some erroneous info.
  6. First reaction: Oh, come on Canon! Why? What's up with the mediocre spec advancements for another $5,500?

    10 minutes later after considering all options: Well, I can't switch systems and lenses after spending all that money, and Canon did give me a few more fps and more focal points in live-view than the previous model, so...


    But then yet, the real specs haven't been released yet, so there is still hope!....maybe.
