The ultimate EOS is here, making way for a new era in autofocus speed, accuracy and precision - the EOS-1D X Mark III. Offering the highest level of performance an EOS DSLR has ever possessed, the EOS-1D X Mark III changes the game for serious photographers around the world, boasting a powerful new 20.1 Megapixel Full-frame CMOS sensor, combined with a cutting-edge new DIGIC X image processor, for truly outstanding stills and video. Track subjects with incredible focus using the new 191-point AF system - including innovative new Head Detection AF technology (EOS iTR*1 AF X) - along with faster continuous shooting speeds of up to 16 fps with the viewfinder and up to 20 fps in Live View mode. The EOS-1D X Mark III is also our most powerful DSLR for video to date, equipped with 4K 60p video capability, plus the option to shoot 5.5K RAW video or 10-bit 4:2:2 video with Canon Log, recorded to a CFexpress card in either or both of the available dual card slots. And, with built-in Wi-Fi®*** for the first time ever in an EOS-1D series, this revolutionary, dust and weather resistant camera offers the connectivity to share photos and videos with clients, colleagues or family from virtually anywhere. The EOS-1D X Mark III - raising the bar on pro DSLR quality and performance.

Dust Deletion Feature
(1) Self Cleaning Sensor Unit
- Self-cleaning can be done automatically when the power is turned on/off.
- During manual cleaning ([Clean now]), the data for light spot correction is also obtained.
- The coordinates of the dust adhering to the low-pass filter are detected by a test shot and appended to subsequent images.
- The dust coordinate data appended to the image is used by the EOS software to automatically erase the dust spots.
Design Rule for Camera File System 2.0 and EXIF 2.31*
* Supports time difference information.
JPEG (8bit), HEIF (10 bit), RAW (14 bit, Canon original)
|L||Approx. 20.0 megapixels (5472 x 3648)|
|M1||Approx. 12.7 megapixels (4368 x 2912)|
|M2||Approx. 8.9 megapixels (3648 x 2432)|
|S||Approx. 5.0 megapixels (2736 x 1824)|
|L||Approx. 20 megapixels (5472 x 3648)|
|RAW||RAW / C-RAW|
The following three types of file numbers can be set:
(1) Continuous numbering
- The numbering of captured images continues even after you replace the card.
- When you replace the card, the numbering will be reset to start from 0001. If the new card already contains images, the numbering will continue from the last recorded image in the card.
- Resets the file number to 0001, and creates a new folder automatically.
RAW + JPEG Simultaneous Recording
Simultaneous recording of any combination of RAW/C-RAW and JPEG or HEIF image-recording quality is supported.
