Reviewer Consensus

Strong

The Canon EOS-1D X Mark III stands as a premier professional DSLR, delivering class-leading autofocus, rapid burst speeds, and robust build quality for sports and wildlife photographers. That said, its reliance on traditional DSLR mechanics and lack of modern mirrorless features like IBIS or an articulating screen may limit its appeal for some video-focused users.

    Canon's EOS-1D X Mark III is currently the camera to beat in its class. It churns out great images right out of the camera, has class-leading dynamic range and makes for a powerful video camera.

    In terms of video, the 1Dx Mark III also becomes Canon's most capable model below the Cinema series, making it an extremely flexible camera for stills and movies.

    Honestly, in my opinion, this is the hybrid content creator's dream, okay? Meaning if you are a still photographer, you do a lot of action, a lot of sports, but you also are creating a good amount of content for whatever medium you might need it for.

    I do want to finish this up and tell you that this is one of the greatest, if not the greatest, DSLRs ever made, and it's going to have a short life, and this will be the last of the greatest DSLRs. What they did with this camera is fantastic.

    Put simply, there is nothing this camera doesn’t do well and it’s this reliability – the assurance that you’re going to get exactly what you want every time you press the shutter – that extends its desirability well beyond photographers with a specific need for speed.

    The Canon 1D X Mark III definitely proved that it could lock focus even in low light, and wrote to the two CFExpress cards faster than my flash units could keep up.

  • The EOS-1D X Mark III enables Canon to remain at the cutting edge of digital SLR technology and is a worthy successor to the Mark II model. The introduction of the HEIF file format and RAW video recording will help it to maintain this position.

    At the end of the day, this camera is fantastic in what it offers. While prosumers and photography enthusiasts may look at the EOS-1D X with desire, the price tag really means it’s really only going to appeal to professionals who can leverage it for regular paid work.

    The Canon 1D X Mark III (Amazon, B&H) is, in my opinion, the greatest DSLR ever made for video, and it gives mirrorless cameras a run for its money.
