CMOS Image Sensor

Sensor Technology that Canon Constantly Improves on

An image sensor receives light entering through the lens, and converts it into electric charge for generating an image. CMOS sensors are characterised by their relative ease in achieving a high pixel count and high sensitivity. The first EOS camera with a built in CMOS sensor was the EOS D30 that was released in 2000, an era when the use of a CCD sensor was still the norm among digital cameras. Anticipating its potential, Canon adopted the CMOS sensor ahead of its competitors, and has been leading the industry through its emphasis on in-house development and manufacturing, as well as its pursuit to achieve low noise and high image quality. Today, almost all DSLR cameras in the world use the CMOS sensor.

2 Types of Sensor Sizes

In the line up are models with pixel counts of about 18 to 50.6 megapixels. All of the EOS DSLR cameras employ a high-resolution and high-performance CMOS sensor to enable high-definition expression.

Full-Frame CMOS Sensor

Approx. (Horizontal) 36mm × (Vertical) 24mm

A larger sensor size and bigger pixels also means that each pixel can easily take in more light, making it easier to curb noise occurrence. This enables the smoother reproduction of colour gradations. As the depth of field becomes shallower the larger the sensor size, it leads to a better bokeh effect.

Full-Frame: 1D C, 1D X II, 5D IV, 5DS, 5DS R, 6D II, 6D

APS-C Size CMOS Sensor

Approx. (Horizontal) 22.3mm × (Vertical) 14.9mm

Offers a good balance between cost and image quality. When the same lens is used, APS-C size sensors have a telephoto effect that is about 1.6 times the focal length of a full-frame sensor. It also allows for a faster continuous shooting speed.
* The sensor size varies slightly depending on the model.

APS-C: 7D II, 80D, 77D, 800D, 750D, 700D, 200D, 3000D, 1500D, 1300D, 1200D, M6, M5, M3, M100, M50, M10
