Specifications

The EOS-1D Mark IV camera has a new APS-H-size (imaging area 27.9 x 18.6mm,
approximately 1.3x lens crop) CMOS sensor developed and manufactured by Canon, using
semiconductor manufacturing equipment also designed and manufactured by Canon.
This sensor enables professional-level performance in every respect. Its resolution is
approximately 16.1 Megapixels (4896 x 3264 pixels). Its normal ISO range is 100 to
12,800. The range can be extended via ISO Expansion down to L: 50 and up, via H1, H2
and H3 to 25,600, 51,200 and, incredibly, to 102,400 Its low noise, high-speed signal
reading produces 10 fps in continuous
shooting, even with noise reduction
on. In addition, the sensor handles
Live View full HD video shooting.
In all, it is a remarkable example of
cutting-edge sensor technology.
Despite a smaller pixel size than that of the EOS-1D Mark III (5.7 versus 7.2 microns),
design objectives—now achieved— for the new sensor included: a superb S/N ratio,
high-speed and low-noise image development, high ISO speeds and wide dynamic range.
Canon’s improved semiconductor fabrication technology has enabled a
new method of photodiode construction. Photodiode area is optimized
and photoelectric conversion efficiency is improved. This allows more
light energy to be accumulated and transferred even though pixel size has
been reduced.
To improve light-gathering efficiency further, another new and critical
process has been incorporated in the fabrication of the microlens over
the sensor so that there is no gap at all between the microlenses.
Additionally, the distance from the microlenses to the photodiodes
has been reduced compared to earlier designs, improving efficiency
even further.
