18 MP APS–C CMOS Sensor
Designed and manufactured by Canon, the sensor produces an outstanding image and offers fantastic performance at high and low conditions, thanks to a new photodiode and microlens construction.

ISO Range
The EOS 7D enables photographers to capture subjects in their natural light.  The ISO range (100 – 6,400) is expandable to 12,800.

Dual “DIGIC 4” processors
By utilizing Dual “DIGIC 4” processors, users of the EOS 7D never have to compromise between shooting speed, image quality and ISO performance.

Canon CMOS sensor
The EOS 7D includes a new 18 megapixel CMOS sensor with a wide ISO range that delivers excellent results in both the low and high-speed ranges as well as improved image quality. The sensor is a standard APS-C size (22.4x14.9mm) and produces an effective field of view of 1.6x the lens focal length.

The EOS 7D sensor features condensed circuitry with improved sensitivity and increased capacity of the photodiodes, which enables shooting at high ISO and prevents overloading when shooting in bright conditions. The ISO range (100 - 6400) is expandable to 12800 enabling photographers to capture subjects in their natural light without the use of a flash.  

The EOS 7D sensor includes gapless microlenses that have been moved closer to the photodiodes.  These technological advances, which were developed and manufactured by Canon, improve the signal to noise ratio creating very clean high ISO images.

Dual “DIGIC 4”

DIGIC 4 removes the highly noticeable color noise as well as reducing luminance noise without loss in detail, allowing for very clean high ISO images. Even at ISO 6400 noise levels are similar to those of ISO 1600 from DIGIC III.  Auto Lighting Optimizer is now also available during manual exposure, without any drop in performance.
