T
he EOS-1D
Mark IV is one of
the most dynamic cap-
ture devices yet.
Working with children
requires a
lot of
patience
and speed.
The Canon
EOS-1D Mark IV is
perfect. It gives me the
ability to shoot a more
journalistic style and
capture the true
essence of my subjects.
The high ISO allows
me time to think about
the final image, rather
than worry about
where I am going to
find the light. I have
the freedom to work
fast and it provides the
superior image quality
my clients demand.”

Wide ISO Range
The EOS-1D Mark IV has the
largest ISO range in the history
of EOS cameras, with an
improved normal range of ISO
100 – 12800 and an expanded
range of 50 to 102400! The combination
of Dual DIGIC 4 Image Processors and the Canon CMOS
s ensor ensures that even at a setting of 102400, noise is
kept to a minimum.
Noise Reduction Technology
The EOS-1D Mark IV’s CMOS sensor incorporates a unique
on-chip noise reduction technology to deal with both fixed
pattern and random noise. It features a photodiode con-
struction that
results in an
improved pho-
toelectric con-
version rate.
This speedier
conversion
means faster
and increased sensitivity at the pixel level. This speed and
sensitivity, in combination with new gapless microlenses
plus less space between microlenses and photodiodes,
means a better signal-to-noise ratio, which translates to
better real world performance and image files.
16.1 Megapixel CMOS Sensor
The EOS-1D Mark IV’s amazing CMOS sensor captures
a tremendous level of resolution with striking detail
down to each individual pixel. With size to spare, it’s
easy to crop images or to make massive enlargements
without concern of losing detail. A marvel of technical
innovation, the EOS-1D Mark IV’s CMOS sensor incor-
porates a number of significant refinements that
enhance the performance and speed in the capture of
each image. Thanks to advanced, in-house design and
manufacturing, the EOS-1D Mark IV’s sensor has more
pixels than its predecessor with less digital noise,
higher ISO sensitivity and greater dynamic range.
Dual DIGIC 4 Image Processors
The EOS-1D Mark IV’s Dual DIGIC 4 Image
Processors work in concert with the Canon
CMOS sensor chips to improve image quality and make
every camera action faster and more intuitive. Features
like Face Detection Live mode AF, Full HD Video, the
amazing Canon Auto Lighting Optimizer, Lens Peripheral
Illumination Correction and more are all possible thanks to
the speed and processing power of the EOS-1D Mark IV’s
Dual DIGIC 4 Image Processors.
