Canon EOS-1D X Mark III

Canon finally produce a hybrid DSLR worthy of a podium place!

The Canon EOS-1D X Mark III is a professional "hybrid" DSLR. This means it will shoot both 20.1 megapixel stills up to 20fps plus up to 5.5K RAW video. It does this using a new DIGIC X image processor and Dual Pixel CMOS Autofocus recording to dual CFEexpress cards. Price is $6,499 body only.

I have to say that barring a full flippy out screen, the Canon EOS-1D X Mark III has just about everything I could dream of in a DSLR. This is almost enough for me to want to switch back from mirrorless for my video work...almost. A full HDMI connection would have been nice too.

This camera is a beast, there is no denying that. It has all the specs that I wanted to see in the Canon EOS 5D Mark IV but couldn't wait this long! When you look at the specs below, it has pretty much everything both stills shooters and videographers need.

However, for me it is a bit bulky for the type of video work I do. I guess this is still a stills camera with (excellent) video specs!

For stills shooters, myself included, this is a dream machine. Let's look at the main specs:

  • 20.1 Megapixel full-frame CMOS sensor
  • Newly designed low pass filter
  • New DIGIC X image processor
  • ISO range of 100 to 102400 (Expandable to H3: 819200!)
  • Dual pixel CMOS AF
  • Continuous shooting up to 16 fps
  • Continuous shooting up to 20 fps in Live View with AF/AE tracking
  • Maximum burst rate of 1000 images for up to 500,000 shots in the buffer (!?!?)
  • Bluetooth connectivity direct to Smartphone
  • Dual CFexpress card slots
  • 4K 60p, 10-bit 4:2:2 and 5.5K RAW internal video shooting
  • Maximum bitrate in RAW is 2600 Mbps
  • 1080P videos up to 120 frames per second
  • Peaking and focus guides available
  • 3.5mm headphone and 3.5mm microphone jacks
  • Built-in Wi-Fi and Bluetooth
  • Purchase the optional WFT-E9 wireless Transmitter for additional transfer power in congested areas 
  • Dust and Weather resistance

Downsides of the Canon EOS-1D X Mark III

  • No articulating screen (downside for some)
  • Mini HDMI (not full HDMI) limited to 4K
  • Sensor is not stabilized although Canon has included Movie Digital IS
  • Dual Pixel CMOS AF doesn’t work in 4K 50P/60P uncropped modes and 5.5K RAW 60P
  • Battery life only around 4 hours and 40 minutes at 23°C
  • Heavy
  • Pricey

Personally, and if I had the money to spare, I would buy the Canon EOS-1D X Mark III in a shot. It is an amazing camera and I look forward to seeing results in the real world. Both stills and video. More info at Canon UK.

  • If you do video why don’t you buy a video camera?

    • Good question. I love to shoot stock and I never know what I might see when out and about. It may be “stills-worthy” or it may be better as 4K video. Therefore a decent hybrid camera has always been a dream of mine and this is pretty much it.

      Also, for a lot of people starting in business, splashing out separately for a good stills DSLR and decent 4K video camera might be a stretch.

      However, I do agree that a professional DSLR purely for stills, and dedicated video camera for footage is the way to go.

      I bought the 5D Mark IV purely for stills and rarely use it for video. I bought the Panny GH5 purely for video and rarely use it for stills.
