2020 marks the 30th anniversary of the EOS 1 series.

The majority of professional photographers at the Rugby World Cup are using Canon DSLR cameras and EF lenses.

Canon have now made a technology announcement about the new EOS-1D X Mark III camera, revealing a number of facts about it.


The EOS-1D X Mark III will utilise a new AF algorithm with deep learning, that's more consistent and reliable than Canon's current AF technologies.

It will have a new AF sensor with 28x more resolution than the one used in the previous Mark II model when using the optical viewfinder, and will focus over a greater EV range that makes it more capable in low-light.

Live View and Movie AF will use exactly the same algorithm as the optical viewfinder.

The EOS-1D X Mark III will use Canon's proven Dual Pixel CMOS AF system with 525 AF points and 90x100% coverage.


The EOS-1D X Mark III will use a new CMOS sensor with better high-ISO performance than the previous model, along with a new processor.

The 10-bit HEIF file format will be supported.

Burst Shooting

The EOS-1D X Mark III will be able to shoot at 16fps when using the optical viewfinder and 20fps when using Live View. These rates are achieved using either the mechanical or electronic shutter, both of which support autofocus and exposure.

Memory Cards

The EOS-1D X Mark III will use the CF Express memory card format via dual card slots to deal with the file sizes and speed of the camera, offering 5x the Raw burst depth of the Mark II model.


The EOS-1D X Mark III will be able to record 4K 60p video with 10-bit Canon Log and internal Raw recording, although it's unclear at this point if it will be able to do all three of those things at the same time.


This is a big feature of the new Mark III 1D X, being of great importance to the Olympics sports photographers who will be using it in Japan next year. 

The EOS-1D X Mark III will have built-in wi-fi, Bluetooth and Ethernet connections, the latter being twice as fast as on the Mark II camera thanks to a new WFT-E9 wireless transmitter.

Build Quality and Controls

The EOS-1D X Mark III will have a magnesium alloy body.

It will feature a brand new AF point selection control and have illuminated buttons.

Battery Life

Despite using exactly the same LP-E19 battery as the Mark II, the new Mark III camera willoffer much better battery life.
