New 10.1 Megapixel
Sensor
The CMOS sensor in the EOS 40D has been
designed and developed by Canon, and is made by
Canon using semiconductor manufacturing equip-
ment that was also designed and manufactured by
Canon. The performance and value benefits that
result from this integration are enormous. The EOS
40D boasts the highest performance in its class:
approximately 10.1 megapixels, ISOs from
100–1600* in 1/3 steps plus 3200, high-speed
signal reading with 6.5 fps shooting, Live View Function silent shooting mode with
electronic 1st-curtain shutter, and much more.
* Standard output sensitivity. Recommended exposure index.
Although the EOS 40D’s single-piece CMOS sensor is based on the Canon EOS Digital
Rebel XTi’s sensor design and manufacturing technology, new processes were incorporated
in the CMOS semiconductor fabrication and microlens-forming process. By improving
light-collecting efficiency, the same ISO range and low noise (S/N ratio) as that of the
EOS 30D were attained even though the pixels on the 30D are larger.
The combination of 4-channel reading per line and high-speed signal reading (about
twice as fast as the EOS 30D, which also has 4-channel reading), together with a
redesigned 2 motor system for charging the reflex mirror and shutter independently (see
page 13), enables approximately 6.5 fps continuous shooting.
