EOS CAMERAS
Lens Peripheral Illumination  
Correction
Another feature available in Canon’s newest  
EOS cameras is Canon’s Lens Peripheral 
Illumination Correction feature. Taking into 
account the lens in use, this feature automatically 
brightens the light level at the four corners of 
the composition where light falloff may have 
occurred. Peripheral illumination characteristics 
and correction data are detected automatically 
on a number of Canon lenses and can be 
entered manually through Canon’s EOS utility 
software. This function can be applied when 
shooting to JPEG images, and in post-processing 
with RAW images.
Highlight Tone Priority
Loss of highlight detail is one of the greatest 
concerns for photographers shooting digitally 
in brightly lit and high-contrast situations. 
Canon’s Highlight Tone Priority function 
calculates the exposure to expand the image’s 
dynamic range so that more detail is preserved 
in highlights. This 
renders a more 
continuous tone 
image without 
blown highlights, 
and helps to save 
time in  
post-processing 
for highlight 
retrieval.
removing an even greater amount of dust, 
especially smaller particles. The IR/UV 
absorbing glass in front of the camera’s 
sensor is treated with an anti-dust fluorine 
coating, making it easier to remove damp  
or sticky dust particles.
fine-tuned in other modes. The Canon Auto 
Lighting Optimizer helps produce beautifully  
exposed images that require little to no 
post-production work. 
Lens Chromatic Aberration Correction
With the advanced processing power of 
 
Image Processors on select EOS DSLR cameras, 
chromatic aberration in Canon lenses can be 
corrected at the time of shooting. Select models 
can read the correction data from a lens and 
that lens can be 
registered to the 
camera. These 
cameras can  
also distinguish 
between different 
lenses of the  
same model by 
supporting 
registration of 
serial numbers 
(with compatible 
EF lenses). 
Custom Function
Camera operations are enhanced by Custom 
Functions, conceptualized and developed by 
Canon. Custom Functions enable photographers 
to tailor features and operating functions to suit 
their own shooting style, or to optimize camera 
performance for specific subjects, shooting 
conditions or a signature style.
Advanced RAW+JPEG Recording  
(in-camera processing)
Best described as “digital 
negatives,” RAW images contain 
pre-processed image data as 
captured by the sensor and, 
with post-processing, they yield 
the highest image quality possible from an 
EOS camera. While professionals and advanced 
amateurs often prefer to shoot in RAW mode, 
JPEG images take up significantly less storage 
space and are often more immediately pleasing 
to the eye. With Canon’s EOS cameras, images 
can be captured in a number of RAW and JPEG 
modes, depending on the camera’s sensor, as 
well as record numerous combinations of RAW, 
sRAW and JPEG images simultaneously. Select 
EOS cameras feature in-camera post processing 
with image correction options like white 
balance, brightness, picture style and more, 
plus image resizing with JPEG images.  
Additional features include Expanded Quick 
Control functions during playback like image 
protect, image rotate, rating, RAW image 
processing, resize, highlight alert, AF point 
and image jump, meaning a streamlined 
workflow can begin in the field. 
Auto Lighting Optimizer
The Auto Lighting Optimizer automatically  
corrects image exposure to help ensure  
accurate brightness and contrast. It can  
actually brighten areas of the composition 
while maintaining highlight details and  
accurate exposure in others, or darken areas 
of the composition while maintaining  
brightness and shadow details in others.  
This remarkable feature is available as both  
an automatic feature in Full Auto and Creative 
Auto shooting modes, and can be used and 
Maximum Durability  
and Performance
EOS cameras are designed 
to perform admirably and 
consistently no matter the 
situation. Many EOS camera 
bodies are constructed of rigid, 
high-strength magnesium alloy 
for rugged performance. The 
EOS-1D X and EOS 5D Mark III 
cameras feature weather-sealing 
surfaces and connection points 
for reliable performance in wet 
and dusty situations. The EOS-1D X even has 
a lightweight shutter with carbon-fiber blades 
that can maintain up to 14.0 fps* performance 
for up to 400,000 cycles and has a minimum 
shutter release lag of 36ms (when shooting at 
maximum aperture).
EOS Integrated Cleaning System
Canon has designed an 
Integrated Cleaning 
System with a Self 
Cleaning sensor unit customized to the 
specifications and performance characteristics 
of each EOS camera that helps combat stray 
dust that can enter the camera when changing 
a lens or when out in the field. The front 
surface of the sensor’s IR-cut/low-pass filter 
cleans itself automatically with ultrasonic 
vibrations every time the camera is turned on 
or off. Removed dust adheres to material 
around the filter to help it stay off. With DPP, 
dust missed by the cleaning unit can be 
captured by Canon’s Dust Delete Data Detection 
and can be erased from the image file.
Ultrasonic Wave Motion Cleaning
Select EOS cameras feature 
Canon’s integrated dust removal 
cleaning, which uses a carrier 
wave type self-cleaning sensor 
unit. Previous dust removal systems removed 
dust adhered to the surface of the infrared-
absorbing, ultraviolet-blocking glass in a  
frontward direction by vibrating the glass with 
ultrasound. The wave-type system effectively 
rolls rather than shakes the dust particles off, 
Built to Perform – Canon EOS cameras are built to go wherever your photography takes 
you. Select cameras are sealed for dustproof and drip-proof measures (EOS-1D X shown).
