Introduction
The Canon EOS-1D X Mark II is the company’s latest pro-level DSLR, now built around a 20.2MP CMOS sensor with Dual Pixel AF technology. It uses a body that’s the most subtle possible evolution of the classic 1D design, which makes sense, given how many of its long-standing professional users will need to find it familiar the moment they use it. Inside, though, almost every aspect of the camera’s feature set has been overhauled – from the autofocus system to the video capability, the ISO range to the card format it uses. Let us talk you through the biggest changes.
Autofocus improvements
The EOS-1D X II features a similar AF module to that found on the previous flagship 1D X, as well as on the 5D Mark III and 5DS/R, but comes with some notable improvements. For a start, the coverage is larger, with the central region expanding vertically by 8% and the 20 points on the left and right flanks extending vertically 24% more than before.
All 61 points can now focus at F8, which will be very useful when shooting telephoto lenses with 1.4x and 2x teleconverters. 41 of those points are cross-type, having both horizontal and vertical line sensitivity. 5 central points are dual cross-type and have wider baselines that offer high precision focusing for F2.8 and faster lenses. The center point works down to -3EV in One-Shot AF. It’s not available in AI Servo because it requires a longer sampling interval, which would slow down AI Servo.
Also improved is AF point illumination, based particularly on feedback from wedding and event photographers. Points can now remain lit red when focusing, which helps you keep your AF point over your subject in dim situations. Additionally, two brightness levels are available so you can fine tune brightness based on your preference.

Metering Sensor
The 1D X Mark II gets a new metering module. It’s now a 360,000 pixel sensor that is used both for metering and to provide scene awareness to Canon’s ‘Intelligent Tracking and Recognition’ (iTR) autofocus system.
The sensor itself is a two-layer CMOS chip, with red, green and blue information captured by the top layer and infrared detected further down into the silicon.
Touchscreen LCD
The LCD screen on the back of the camera has received a significant upgrade. It’s now 1.62 million-dot, up from 1.04 million-dot. This represents a move from 720 x 480 to 900 x 600 pixels and the increase in resolution is noticeable. Images look crisp and clear on the back, thanks especially to Canon’s ‘Clear View’ technology that uses optical coatings to reduce reflections.
The LCD is also touch-enabled, but you can only use touch to select a focus point in Live View, either for stills shooting, or to refocus on subjects during movie shooting. It cannot be used to operate menus, nor (annoyingly) is it enabled in playback.
Battery
The Canon EOS-1D X Mark II ships with a new battery, which allows for 1210 shots on one charge. The nice thing is, the battery compartment remains backwards compatible with the older 1D X battery. However, if you use the older battery, frame rates will drop to 1D X levels (12 fps with AF, 14 fps in live view or with the mirror locked up). Heartbreakingly slow, we think you’ll agree.
Dual Pixel AF
Dual Pixel AF makes its debut on a full-frame sensor with the 1D X II. Every pixel on the sensor is split into two separate photodiodes, one left-looking and one right-looking. Comparing the phase difference between strips of left-looking vs. right-looking pixels essentially allows the camera to determine exactly how much to move the focus element to acquire focus, much as the dedicated phase-detect module in DSLRs do. Approximately 80% of the frame is available for focus using Dual Pixel AF, and the technology is particularly useful not just for this extensive coverage, but for the inherently accurate focus it provides – because focus is performed at the imaging plane, there’s little possibility for mis-focus and the inaccuracy issues dedicate phase-detect sensors in DSLRs display.
Perplexingly, Dual Pixel AF can only be used in One-Shot AF in Live View, meaning it can’t be used to continuously focus (though it can for movies). We weren’t given any reasons as to this limitation, and given that continuous focus is certainly possible – as it works during movie shooting – it seems an odd omission.

Canon embraces CFast (and Compact Flash)
Canon has decided to adopt the CFast standard while also providing a CompactFlash slot for backwards compatibility. The logic of this move is to ‘futureproof’ the camera. For now, Canon has provided the option for super high-speed data rates without alienating its existing audience, who most likely have a large collection of CF cards.
Should you own a CFast card, you’ll be able to capture 170 Raw files in a burst: just a fraction below the 180 JPEGs that its predecessor could manage (the Mark II will shoot JPEGs continuously until you run out of card space). CFast is also required for 4K video recording.
Video capabilities
On paper, the EOS-1D X Mark II has very impressive video specifications – moving far beyond what its predecessor was capable of and incorporating most of what the more niche EOS-1D C offered. The standout spec is the ability to shoot DCI 4K footage (4096 x 2160 pixels) at up to 60 frames per second. This capability is the same as the 1D C, though the X II doesn’t include that camera’s Log Gamma option.
To give faster access to video shooting there’s a Video/Live View switch around the live view button just to the right of the viewfinder. In addition, the camera gains a headphone socket for audio monitoring during recording.
Full HD options
In terms of 1080 video, the camera can record at up to 120 or 100 frames per second (without audio) or at 60, 50, 30, 25, and 24 frames per second, depending on whether you’ve got the camera set to PAL or NTSC mode. Interestingly there’s also the option to capture true 24p footage, as well as the 23.98p approximation offered in NTSC mode.
The camera can output a ‘clean’ signal across its HDMI port, for use with an external recorder or monitor (which could be used to provide focus peaking and zebra warnings, if needed), but this stream is 1080 only, not 4K.
Touch-to-focus video
The other video-friendly hardware change on the 1D X II is the addition of touch sensitivity to the rear LCD. This is only used for a very limited number of features but one of these is to position and re-position with autofocus point during video recording. Combined with the camera’s Dual Pixel AF sensor design, this should make it easy to adjust focus in video without the risk of the lens over-shooting or adding distracting focus wobble to video clips, as can happen with contrast detection autofocus.
Touch to focus can also be used for One-Shot AF in stills Live View shooting.
