new sensor 20 Mpx
fast AF dual system
The EOS 70D features Canon’s all-new Dual Pixel CMOS AF, a revolutionary leap forward in speed and accuracy that unlocks the potential of Live View shooting.
"Dual Pixel CMOS AF is a cutting-edge Canon technology, made possible by a sophisticated redesigning of the CMOS sensor. Traditionally, image sensors have one photodiode per pixel, but the CMOS sensor on the EOS 70D has two photodiodes per pixel, enabling each pixel on the sensor to both perform phase-difference detection autofocus and capture light – a first for EOS cameras. With phase-difference detection AF, autofocus is achieved quickly and easily on the camera. This unique AF system enables autofocus on 80% of the image plane, vertically and horizontally, and helps ensure virtually no loss in image quality."
