EOS CAMERAS
exposure even in the most challenging lighting 
situations. Photographers can choose from 
several additional metering options. Center-
Weighted metering is available for a more 
traditional pattern. Partial metering limits 
readings to sensor zones in the center of  
the image area, offering more area-specific 
control. Spot readings can be taken at the 
center of the frame area or linked to an AF point 
on specific models. With certain EOS cameras, 
up to eight separate spot meter readings can 
be recorded and averaged. On select EOS 
cameras, the iFCL (Intelligent Focus Color 
Luminance) 63-zone dual-layer metering 
system incorporates the color wavelength 
surrounding the chosen focus point to help 
ensure more natural color rendition. The 
outstanding exposure control technology that 
Canon has created is also fully integrated with 
the flash photography tools of the EOS System. 
E-TTL (Evaluative Through-The-Lens) and 
E-TTL II autoflash systems work in combination 
with the camera’s multi-zone metering sensor 
to help take the guesswork out of flash  
photography. (See the Speedlite section  
for more details.)
shooting options, both the EOS-1D X and  
EOS 5D Mark III have a dedicated AF menu tab, 
while the EOS 7D Mark II has a special AF area 
selection lever so AF settings are faster and 
easier to access. 
Superb Exposure Control
Canon EOS cameras incorporate advanced 
exposure control systems, offering amazingly 
precise auto exposure with a wide range of 
metering options. Full-frame evaluative 
metering incorporates the camera’s multi-zone 
sensor reading with specific focusing point 
data. The onboard microcomputer compares 
input from all zones and calculates optimum 
Autofocus Technology
The EOS System leads the way in  
AF technology with multi-point AF 
systems that deliver a combination 
of accuracy and speed in diverse 
situations. The EOS-1D X, EOS 5DS, EOS 5DS R, 
and EOS 5D Mark III cameras are benchmarks 
in AF technology with a 61-Point High Density 
Reticular AF. The EOS 7D Mark II camera has a 
65-point
§
 all cross-type AF. These AF technologies 
improve tracking and are remarkably sensitive 
in low-light situations (the EOS-1D X, 5DS, 5DS R, 
and 5D Mark III offer EV -2 for a central point with 
an f/2.8 lens, and the EOS 7D Mark II offers  
EV -3 with an f/2.8 lens). The cameras can 
remain stable in adverse conditions, with 
secondary imaging sensors that use temperature- 
and humidity-resistant glass molding. With the 
EOS-1D X and EOS 5D Mark III cameras’ firmware 
updates
, cross-type autofocusing is possible 
when the maximum aperture of a Canon EF lens 
becomes f/8 with an EF extender attached.
Face & Tracking Priority AF detects faces and  
enables the camera to focus and track the 
selected face by switching the AF points. After 
detection, face tracking will continue even if the 
face turns to the side view. Other parts of the 
body besides the face can also be selected on 
the monitor and can be tracked in the same way. 
High-Speed Shooting
The AF systems in the EOS-1D X and  
EOS 7D Mark II cameras combine fast data  
readout (16-channel and 8-channel,  
respectively), image processor speed (Dual 
5+ Image Processors and Dual 
6 
Image Processors, respectively), speedier 
shutters and mirror systems that help to raise 
the performance bar for digital cameras.  
A mirror mechanism provides improved AF 
precision, speed and stability. The main mirror 
is equipped with two balancers and one  
bounce-lock mechanism, and the sub-mirror 
has two balancers and two bounce-lock 
mechanisms, thus effectively controlling 
mirror bounce. This contributes not only to 
high-speed continuous shooting, but also to a 
stable viewfinder image plus greater AF and 
AE accuracy.
*   The maximum continuous shooting speed is restricted to up to 10 fps when the battery charge is less than 50% or when ISO speed is above 32000. If the camera’s internal temperature is low and 
ISO speed is above 20000, the maximum continuous shooting speed is restricted to up to 10 fps.

Enhanced Subject Tracking
Reliable subject identification and tracking 
features significantly improve a camera’s 
performance in any number of situations. On 
select EOS cameras, EOS iTR AF can use both 
face detection and color to track a subject. 
With acceleration and deceleration tracking, 
the EOS-1D X camera’s AI Servo AF system can 
adjust and react to sudden stops and starts. 
For the EOS 7D Mark II camera, iTR AF has been 
enhanced with tracking algorithms optimized 
for more precise performance. EOS iTR AF is 
especially perfect for sports and wildlife 
photography. Specific parameters can be 
adjusted and refined, then saved in the AF 
menu for later use.
EOS iSA System
The 100,000-pixel RGB Metering Sensor with 
a dedicated DIGIC 4 Image Processor in the 
EOS-1D X camera helps deliver substantial 
improvements in evaluative ambient and flash 
metering. The sensor has 252 distinct zones, 
reducing to 35 zones in low light. It detects face 
and color to perform more accurate subject 
recognition, which is used to enhance the 
performance of the AE, E-TTL and AF systems. 
The EOS 5DS, EOS 5DS R, and EOS 7D Mark II 
cameras have a Intelligent Subject Analysis 
(iSA) system that employs an independent RGB 
light sensor with approximately 150,000-pixel 
resolution. With this sensor, not only do the 
cameras have a finer level of accuracy, but 
when combined with the cameras’ iTR AF, they 
can track subjects with a significantly greater 
level of success. The EOS 5DS, 5DS R, and 
7D Mark II also have an Anti-Flicker Shooting 
function that compensates for flickering light 
sources, taking shots only at peak light 
volume. This feature is useful for helping 
minimize disparities in color and exposure, 
especially during continuous shooting in 
sub-optimal lighting situations.
Enhanced Live View Focusing
Innovative AF systems also enhance continuous 
subject autofocusing and tracking in Live View 
shooting on select EOS cameras.
Hybrid CMOS AF combines phase and contrast 
detection AF to increase autofocus speed 
during Live View and video shooting on select 
EOS Rebel cameras. Hybrid CMOS AF is aided  
by pixels on the camera’s CMOS sensor that 
assist in predicting subject location, making  
continuous focus tracking quick and accurate, 
while enhancing focusing speed. Performance 
capabilities are extended with a number  
of selectable zones. Hybrid CMOS AF II  
(EOS Rebel SL1 camera only) offers a widened 
focus area covering 80% of the image plane, 
vertically and horizontally, for increased focus 
accuracy and speed. The EOS Rebel T6s and  
EOS Rebel T6i cameras have Hybrid CMOS AF III 
for even faster and precise AF.
FlexiZone Multi mode divides the scene into 31 
AF zones and uses special algorithms that give 
priority to the center and closer subject for 
focusing. Taking advantage of the touch screen 
LCD monitor featured on select EOS cameras, 
users can simply touch one of nine zones 
(center left, center right, center, center top, 
center bottom, and the four corners) and select 
it for automatic focusing. For selecting a single 
AF point, cameras with a touch screen also 
feature Touch AF. 
Multi-zone Metering — Canon’s sophisticated Multi-zone 
Evaluative Metering System considers not only the active 
focusing point, but also a range of metered values 
throughout the frame to determine correct exposure even 
in difficult lighting.
AF Modes
Canon EOS cameras feature a number of 
dedicated autofocus modes designed to 
enhance reliability in specific shooting 
situations. One-Shot AF mode is ideal for 
static subjects — the camera rapidly selects 
the optimum focusing point and the subject  
is instantly brought into focus, even when 
off-center. AI Servo AF mode is excellent for 
moving subjects. Aided by a highly intelligent 
predictive focusing algorithm, it precisely 
tracks subject movement across the wide AF 
coverage area, automatically shifting the 
active focusing point vertically and horizontally 
as required. AI Focus AF mode, in which the 
camera automatically decides between 
One-Shot and AI Servo AF modes based on 
subject movement, is ideal for shooting 
unpredictable subjects. AI Servo AF III, found 
on select EOS DSLR cameras, uses more 
advanced algorithms for even better predictive 
focus tracking performance when shooting 
subjects with unpredictable movement. Even 
difficult, high-magnification subjects, such as 
a flower in a breeze, can be captured accurately 
with a Canon macro lens using these tracking 
algorithms. With the firmware update
, the 
viewfinder of the EOS-1D X can be illuminated 
in red (intermittently) when the shutter button 
is pressed halfway during AI Servo AF, for easy 
viewing and shooting in low light.
Diverse AF Shooting Options
On the EOS-1D X, EOS 5DS, EOS 5DS R, and 
EOS 5D Mark III cameras, there are 6 AF point 
selection methods: spot, single point, single 
point and adjacent 4 points, single point and 
adjacent 8 points, zone selection and full 
automatic, plus there’s a dedicated AF  
configuration tool for control of AI Servo AF 
tracking parameters.
The EOS 7D Mark II camera also has the same  
6 AF point selection modes, and includes a  
new Large Zone AF mode. To manage all of the
