Auto Focus - EOS-1D X Mark II

Lock, track and shoot

Photography so sharp it’s dangerous.


360k RGB+IR Metering Sensor

The camera has an RGB+IR metering sensor with 360,000 effective pixels (736 x 496 near WVGA resolution). Evaluative metering and evaluative flash metering are based on the information detected by the sensor. The sensor includes IR pixels that detect infrared (IR) light, which helps the EOS Scene Detection System analyse scenes and improve AF precision. The IR pixels, together with the RGB pixels are also used to detect brightness, colour and faces in a scene. In addition to taking distance information into account, the algorithm recognises a subject based on face detection and colour information.

The metering sensor is supported by a dedicated DIGIC 6 processor, which processes all the colour information and face detection data to recognise shooting subjects with outstanding accuracy.


EOS iTR System

The face detection and colour tracking abilities of the 360,000 pixel RGB+IR sensor are passed onto the EOS Intelligent Tracking and Recognition system. On the EOS-1D X MARK II, EOS iTR AF includes the improved algorithms found on the EOS 7D Mark II that greatly enhance the overall subject tracking performance.

In addition to face priority mode, a subject tracking mode has been added for moments when a face is not always visible, and when the main subject is not a person.


AI Servo AF III+

Canon’s AI servo AF III+ features an AF algorithm that, along with the EOS Intelligent Tracking and Recognition (EOS iTR) system, improves the tracking sensitivity in scenes where subject movements may occur suddenly, delivering precise and accurate focusing even in situations where focusing is difficult.

The EOS-1D X Mark II features six AF Case study settings to help you choose the most appropriate option for your subject. These case studies provide different setups for the three different AF preference settings of Tracking Sensitivity, Acceleration/Deceleration tracking and AF Point Auto Switching. These parameters can be further customised based on personal preferences.

61-point Expanded Autofocus Area


Increasing the area covered by the AF points is a much requested feature by photographers, be they professional or amateur. In the EOS-1D X Mark II, the AF points have been placed over a wider area – an 8 percent more vertical expansion in the central area, and 24 percent more vertical expansion in the peripheral area – giving greater freedom in where subjects can be placed when composing.

41 cross-type and 5 dual cross-type AF1 points further extend the reach of the EOS-1D X Mark II’s focus capabilities. Cross type AF points provide greater autofocus precision over a wider area of the frame ensuring correct focus, important for fast moving subjects. All 61 AF and 41 cross-type AF points are individually selectable.

AF Point Selection

Use all 61 AF points together, or group them into moveable zones that cover off-center subjects. Alternatively, select just a single AF point to focus precisely on a specific part of the scene.

The Large Zone that was popular on the EOS 7D Mark II has been added to EOS-1D X Mark II, enabling tracking of moving subjects and making it really effective for precise compositions when the subject is at speed.

61 AF Points, With 21 Cross-type AF Points at f/8


Wildlife and sports photographers often have to use super telephoto lenses with extenders to get closer to their subjects. This limits the AF usability because of the resulting f/8 aperture setting. The 1-point f/8 AF compatibility on the 1D X has been significantly increased to a maximum of 61 points2 on the EOS-1D X Mark II, with 21 cross-type points. The Zone AF - which makes subject tracking easy - and EOS iTR AF provides powerful subject tracking support even with super telephoto and extender shooting.

Auto Focus at EV-3

The AF system makes it easier to keep the subject in focus, even in challenging light. The AF low-intensity limit has been improved to EV-33, making it easy to shoot in scenes where autofocusing was previously impossible or too slow and inaccurate, such as dark locations.

Red Illuminated AF Point Display

A feature first found on the EOS-1D Mark IV, the AF frame displayed in red has been reintroduced based on feedback from EOS-1D X users. Along with the illuminated frame display, the EOS Intelligent Scene Analysis System and red super imposition display optical system have been brought to the EOS-1 series. Because it is easy to identify the AF point in dark places and easy to instantly select an AF point, framing is made easier in low-light conditions.


Flicker Detection

Under flickering light such as fluorescents, using a faster shutter speed may result in irregular exposures and colours due to the light’s flicker frequency. EOS-1D X Mark II – like the EOS 7D Mark II, EOS 5DS R and EOS 5DS – detects flicker frequency of light sources and adapts the shooting timings to capture the image near peak brightness to reduce flicker effects. This function works with a flicker frequency of 100Hz and 120Hz and has an improved algorithm to prevent the incorrect detection of flickering light.
