The EOS-1D X Mark III is the latest high-end, ultra-tough, hyper-fast DSLR from Canon. From the outside, it looks about the same as previous EOS-1D bodies dating back two decades. But on the inside, there are radical updates. And even though this is a big, double-grip DSLR, it functions as a highly capable mirrorless camera in Live View mode provided you've got the muscle to hold it out in front of you for extended periods of time.

This is also a camera that can take you beyond 8-bit JPEG shooting as your 'finished image', includes AF subject recognition based on machine learning in both OVF and live view shooting, and has some impressive video capabilities (including internal Raw video).

There's a lot to cover on the EOS-1D X Mark III, so let's get started with a rather lengthy list of key specifications before diving into just what this all means on the following pages.

Key specifications:

  • Updated 20.1MP CMOS sensor with Dual Pixel AF
  • Digic X processor
  • HEIF 10-bit recording (supports HDR display at smaller-than-JPEG sizes)
  • 16fps bursts (viewfinder), 20fps bursts (Live View) with autofocus
  • All-new mirror mechanism to reduce vibration and blackout
  • 191-pt viewfinder AF system with new 'square pixel' design, 155 cross-type points, Face + head detection, sensitivity to -4 EV, all points support F8 shooting
  • Live View AF system is now 90% horiz / 100% vertical coverage with enhanced eye detection, sensitivity down to -6 EV, supports F11 shooting
  • New AF 'Smart Controller' built into the AF-ON buttons
  • 5.5K/60p 12-bit Raw video recording, 4K/60p 4:2:2 10-bit H.265/HEVC recording
  • Dual CFExpress card slots for virtually unlimited buffer in most situations
  • CIPA rated to 2850 shots with the viewfinder, 610 with Live View using LP-E19 battery
  • Shutter rated to 500k shots
  • Weighs 1440g

And those are just the key specifications.

The EOS-1D X Mark III is likely to find its way into the hands of sports, wedding and event photographers, and remain there for years of use and hundreds of thousands of images. Out-of-camera JPEG.

Excepting landscape and studio specialists that need massive amounts of megapixels, the EOS-1D X Mark III is the most well-rounded, well-specced camera currently on the market for both stills and video shooters that have the requisite funds. It's clear that Canon is aiming for the 1D X III to be relevant for professional users for years to come, despite the ever-increasing pace of innovation and ever-decreasing length of product cycles in the industry.

The EOS-1D X Mark III is scheduled to be available in mid-February 2020 for an estimated retail price of $6499 USD, body-only.
