Canon CMOS Sensor
Taking advantage of its own proprietary 
technologies, Canon develops and produces  
its own CMOS sensors. Unlike CCD sensors, 
CMOS sensors convert and amplify signals 
before they are transferred to the image 
processor, enabling them to produce superbly 
clean image data and help reduce power 
consumption by as much as 90%. Data transfer 
speeds are increased by using multi-channel 
signal paths that help dramatically improve 
the camera’s responsiveness. Canon’s  
CMOS sensors incorporate an on-chip noise 
reduction technology to deal with both fixed 
pattern and random noise. In addition, a 
multilayer low-pass filter is placed in front of 
the sensor to help isolate false colors that the 
sensor may detect. Then, Canon’s own 
Image Processor helps eliminate those colors  
while retaining full detail. CMOS sensors  
can also be fabricated to full-frame 35mm 
dimensions, an important consideration for 
photographers who wish to use their lenses 
without a conversion factor. Canon’s CMOS 
sensors deliver outstanding resolution and 
signal purity, making them ideal for critical 
photo or video applications.

One of the many 
benefits of the Canon 
full-frame CMOS 
sensor is the ability 
it gives me to shoot 
handheld in extreme 
low-light conditions. 
Even when shooting 
at a very high ISO,  
I can still capture  
stunning results with 
little to no noise.
The history of Canon EOS cameras is brimming with examples of technological
innovations that have set new industry standards for performance and usability.
And yet, at Canon, technology is never an end in itself. Every technological
advancement must yield tangible benefits to the user. Does a new feature enable 
the camera to more quickly and faithfully respond to the photographer’s will? 
Does a new material or process improve the camera’s long-term reliability?
Canon EOS camera advancements endure because they are designed to enhance 
the photographic experience, whether you are a seasoned professional or a 
beginner. Put simply, the technologies of Canon EOS cameras are impressive 
because of the quality of the images they enable you to create.

Full-frame Canon CMOS Sensor 
The Canon-manufactured 
full-frame CMOS sensor 
delivers professional 
performance with digital 
convenience. EOS DSLR cameras with  
full-frame sensors do not require a focal 
length conversion factor common to other 
DSLR cameras on the market. Instead, these 
cameras deliver the same angle-of-view as 
35mm film cameras, so the working distance 
to the subject, with a given lens, is the same 
as it would be on film. Full-frame sensors 
provide greater control over depth-of-field, 
which helps to create beautiful background 
blur, perfect for portraits. The large sensor 
area also helps to enable a marked reduction 
in noise levels at all ISO values. When 
combined with high resolution and smooth 
gradation from highlights to shadows, Canon 
DSLR cameras with full-frame sensors 
produce images that rival those taken with 
professional medium-format and large-format 
film cameras.
Extensive ISO Range*
EOS cameras feature an extensive ISO range 
for greater flexibility in diverse photographic 
situations. The EOS-1D X camera features  
the extended ISO range of 100–51200 (L: 50,  
H1: 102400, H2: 204800). The EOS 5D Mark III  
and EOS 6D cameras have an ISO range of 
100–25600 (L: 50, H1: 51200, H2: 102400). 
Even at higher ISO settings where a higher 
degree of noise is expected, the renowned 
Canon CMOS sensor and noise reduction 
system work to help ensure superb image 
quality. Accordingly, even demanding 
photographers can use EOS cameras with 
confidence, no matter the light.
Effective Light-gathering
The EOS-1D X camera’s sensor has 18.1 
effective megapixels with individual 6.95µm 
pixels, the EOS 5DS and EOS 5DS R cameras 
have a 50.6 megapixel sensor with individual 
4.14µm pixels, the EOS 5D Mark III camera 
has a 22.3 megapixel sensor with individual 
6.25µm pixels, and the EOS 6D camera has a 
20.2 megapixel sensor with individual 
* Standard output sensitivity. Recommended exposure index.
When using the same lens with different cameras, the 
angle-of-view varies depending on the sensor size.

EOS 5D Mark III Full-frame CMOS Sensor (actual size)
6.55µm pixels. An advanced S/N ratio plus a 
photodiode structure with an increased 
photoelectric conversion rate of sensor on 
these EOS cameras help increase sensitivity by 
approximately 2 stops over previous models, 
meaning higher ISOs with even lower noise.
Advanced 14-bit A/D Conversion 
EOS cameras employ 14-bit converters to 
process the output of the imaging sensor. 
Compared to the 12-bit converters used in 
most digital cameras, the Canon design helps 
ensure smoother tonal transitions, more 
natural gradations, and superb color fidelity. 
RAW images are recorded at 14 bits so that 
processed 16-bit TIFF images contain the full 
range of tonal values captured by the sensor.
 6/5+/5/4 Image Processor 
Designed to help 
maximize performance 
between the capture and 
recording stages of 
digital photography, the  
Image Processor 
uses advanced signal 
processing technologies to help enhance 
image quality and deliver a more intuitive, 
responsive camera. The 
4 Image 
Processor enables Face Detection AF, Live 
View composing, and Full HD video recording. 
The speedier 
5 Image Processor makes 
advanced functions possible like HDR 
Backlight Control and Creative Filters, and  
can support compensation for chromatic 
aberration in both still and moving images. 
5+ Image Processer extends 
performance to greater levels of noise 
reduction at higher ISOs, while Dual 
Image Processers add lightning-fast speed. 
6 Image Processors provide 
turbocharged features like noise-reduction 
processing at ISO 16000, more precise EOS 
iTR AF and tracking of faces during Live View 
and movie shooting, and enabling the camera 
to record Full HD video at 60 fps.
Dual DIGIC 6 Image Processors (EOS 7D Mark II)
High ISO – Whether shooting stills or video, Canon EOS cameras capture silky-smooth low-noise images that are sharp 
with a wide dynamic range of color and tone, even at high ISO speeds.
