Canon 80D

La nuova Canon 80D dovrebbe avere un sensore CMOS da 28Mpx di tipo APS-C
quasi sicuramente utilizzera  un sensore con la nuova tecnologia Dual Pixel la stessa utilizzanta nella versione 7D MkII. accoppiato a un processore ultrarapido   DIGIC 6+


7D Mark II

il sistema di Auto Focus identico a quello della 7D Mkii

Dual Pixel CMOS AF involves a sophisticated rethinking of the CMOS sensor. Traditionally, image sensors have one photodiode per pixel for recording, but the CMOS sensor on the EOS 7D Mark II has two photodiodes per pixel, 40 million in total, enabling each pixel on the sensor to both perform phase-difference detection autofocus and capture light. With phase-difference detection AF, autofocus is achieved quickly and easily on the camera. This unique AF system enables autofocus on approximately 80% of the image plane, vertically and horizontally, and helps ensure virtually no loss in image quality.

The benefits of Dual Pixel CMOS AF are clearly evident in Live View and video shooting, where the EOS 7D Mark II achieves natural, precise focus very quickly, even when switching between subjects. And, combined with the predictive power of Movie Servo AF, subjects in motion are smoothly and consistently tracked – once focus is locked, the EOS 7D Mark II holds on! Plus, with the shallow depth-of-field afforded by EOS optics, video gains a brilliant, cinematic ambience lacking when shooting video with many other Digital SLRs.
