Canon EOS-1D X Mark III | Final Release Info & Spec

Back at the end of October Canon announced the development of their brand new flagship Pro-Level DSLR, the EOS-1D Mark III. With some impressive improvements to the continuous shooting, internal video, low light performance plus much more you can see why Canon is launching this as “Master Speed”.

Key Features

  • 20.1-megapixel full-frame sensor
  • 5.5K Raw video
  • Filmmaking at 4K/60p
  • DIGIC X image processor
  • Up to 20fps continuous shooting
  • Real-time, lag-free, no-delay
  • Deep-learning autofocus
  • Smart controller
  • Dual Pixel CMOS AF
  • Gigabit Ethernet & built-in Wi-Fi + Bluetooth


HEIF image format
The High-Efficiency Image File (HEIF) format is the next generation file format for digital photographers. It’s based on the HEVC/H.265 video codec and allows for higher image quality with no concurrent increase in file size, compared with JPEGs. HEIF files have fewer artefacts and increased dynamic range with 10-bit colour depth.

Deep learning AF
The EOS-1D X Mark III is equipped with a deep learning autofocus algorithm that has been programmed using real-world examples of sports photography from virtually every event you can imagine – from football to athletics and much more. It can recognise the faces of athletes even when they are obscured by goggles or helmets and knows when subjects are upside down – in diving competitions, for example.

DIGIC X Image Processor
At the heart of the EOS-1D X Mark III is a single DIGIC X image processor that operates with incredible speed and efficiency. DIGIC X is responsible for both the camera’s responsive performance – typified by its 20fps continuous shooting 4k/60p oversampled video – and its superlative image quality. The processor enables enhanced DLO, ALO and Highlight Tone Priority, plus very low levels of noise at high ISO.

Gaussian low pass filter
A gaussian low pass filter samples light over a greater number of pixels than a conventional low pass filter, so artefacts such as moire can be tackled while preserving fine sharpness and clarity.

The EOS-1D X Mark III features dual CFexpress card slots, which are capable of writing information at incredible speeds. The camera can capture 1000 shots in a continuous burst and even then only needs two seconds to clear its memory buffers. After consultation with professional photographers, the dual card slots in the EOS-1D X Mark III can be assigned individually to either still photos or video.

Smart controllers
We’ve given the EOS-1D X Mark III a pair of smart controllers – one for horizontal shooting; the other for vertical. These revolutionary devices – which are built into the camera’s AF-ON buttons – are shaped like a traditional joystick but behaviour more like a miniature touchpad that can be used to scroll AF points around the screen. Each controller is customised for sensitivity and speed and reacts intuitively even when you’re wearing gloves. The camera automatically disables the vertical controller when you’re shooting horizontally to avoid accidental movements.

Canon EOS-1D X Mark III | Development Updates

Canon has announced the development of the highly anticipated EOS-1D X Mark III – the successor to the world-renowned EOS-1D X Mark II. Perfect for sports and wildlife, the flagship DSLR is being developed using feedback from the worldwide community of EOS-1D X and EOS-1D X Mark II photographers, including extensive real-world testing with professional photographers globally. Join us as we bring you all the latest news and updates on this new camera.

‘Boasting Canon’s rich heritage creating optically excellent products, the EOS-1D X Mark III offers an impressive step-change in autofocus, with dramatically improved image quality, video and communications.’

For a development announcement Canon has actually far exceeded most expectations on how much information we have been shared and the key spec is listed below.

Key Features

  • Newly developed CMOS sensor
  • Newly developed DIGIC processor
  • 4K60p with 10bit Canon Log internally
  • 16fps with full AF & AE – mechanical shutter
  • 20fps in Live View – mechanical or electronic shutter
  • Shoot in RAW for both Video and Stills
  • New autofocus algorithm
  • New autofocus sensor – 28x the resolution than Mk II
  • 525-AF areas in Live View
  • Dual Pixel CMOS AF System
  • Better ISO performance
  • Capture images in 10bit
  • 5x Longer RAW burst
  • CF Express Card
  • Built-In Wi-Fi & Bluetooth
  • 2x quicker transfer via built-in ethernet
  • Dramatically improved battery life

Unrivalled: a step-change in autofocus

The EOS-1D X Mark III is blisteringly fast – offering exceptional precision, reliability, high-performance autofocus and subject tracking – giving photographers a greater choice when it comes to the perfect shot selection. The camera’s new autofocus algorithm improves stability and tracking – with both optical viewfinder and Live View shooting – using deep learning technology to ensure accurate focus tracking for every shot. When using the optical viewfinder the EOS-1D X Mark III makes use of a new autofocus sensor offering approximately 28x the resolution in the centre of the sensor than the one in the EOS-1D X Mark II – the current go-to camera for professional photographers.

Offering expanded AF brightness range with greater precision, the EOS-1D X Mark III has a range of autofocus capabilities enabling photographers to get ‘the shot’. In Live View users can make use of 525 AF areas using the Dual Pixel CMOS AF system covering approximately 90x100 percent of the image sensor. Using the same AF algorithm as when shooting with the optical viewfinder, it ensures enhanced flexibility when framing subjects, whether it’s a race car on a track or a bird in flight. The EOS-1D X Mark III supports significantly faster frame rates with full AF and AE, using either the optical viewfinder (up to approx. 16fps mechanical shutter) or Live View (up to approx. 20fps mechanical or electronic shutter), in addition to this the camera’s CFexpress card slots enable five times the RAW burst depth of its predecessor.

Challenge creativity - capture everything

A clear example of Canon’s commitment to pushing the boundaries of innovative imaging with optically excellent technology, the EOS-1D X Mark III supports an all-new, Canon-developed, CMOS sensor and DIGIC processor, delivering greater image quality, at even higher ISOs, with the ability to capture stills in 10bit using the HEIF file format. The power of 4K resolution brings stories to life with the capabilities to shoot cinematically with 4K movies including 4K60p with 10bit Canon Log internal recording. Reducing the amount of equipment needed for professionals on any given project, the EOS-1D X Mark III also shoots in RAW for both movie and stills.

Content delivery, quicker than ever before

For professionals, content delivery is just as important as image capture – the EOS-1D X Mark III makes it easy, featuring built-in Wi-Fi and low-energy Bluetooth in addition to GPS. To keep pace with ever-shortening deadlines, the camera transfers data at twice the speed of the EOS-1D X Mark II when using the built-in ethernet, or the new optional wireless file transmitter – the WFT-E9 – which is also compatible with the Canon’s recently launched Cinema EOS C500 Mark II camera. Coupled with simpler network set-up, the EOS-1D X Mark III greatly enhances the professional workflow.

An extension of the professional kit bag

Existing EOS-1D series users will be comfortable handling the EOS-1D X Mark III, allowing seamless navigation with trusted ergonomics – whilst the magnesium alloy body offers the durability expected from Canon’s EOS-1 cameras. Professional photographers can expect the same impressive build-quality as the EOS-1D X Mark II – phenomenal weather-sealing allows the camera to stand up to harsh conditions, including wind, rain and humidity. With incredible low-light shooting capabilities, the EOS-1D X Mark III’s illuminated buttons allow for precision operation in challenging, dark and dimly-lit conditions. The camera also offers a new additional control for selecting AF points, built into the AF-ON button, allowing photographers to change AF points on-the-fly for the best composition – further simplifying their work. Dramatically improved battery life – with the same LP-E19 – also allows professionals to shoot for longer periods of time, without having to change batteries, reducing the chance of missing a shot.
