Digital Camera World Verdict

With the Canon EOS1-D X Mark III, the typically cautious company has released a camera packed with bleeding-edge tech, including deep learning AF, an optical Smart Controller, HEIF and HDR PQ support, CFexpress, 12-bit internal 4K RAW, head tracking and so much more. Canon has combined the advantages of DSLR and mirrorless to produce a hybrid body that can shoot according to what the situation demands. While it lacks the luxuries of mirrorless, this camera does so much that no other system can – it's a genuine glimpse into the future.

The Canon EOS-1D X Mark III has a lot to live up to – and a real fight on its hands to defend its throne. While the world of professional sports photography is still dominated by DSLRs (with 70% of pros at last year’s Rugby World Cup using Canon DSLRs), mirrorless cameras have now come so far that Sony’s latest effort, the Sony A9 II, is a far superior photographic tool than the Canon EOS-1D X Mark II

With the A9 II reigning as the best camera for professionals, Canon really had to pull something special out of the bag with its new flagship DSLR. Thankfully, it has delivered a true hybrid DSLR / mirrorless camera that ushers in a number of inevitably industry standard new features and technologies.
