Full pixel dual core focusing Canon EOS 70D secret weapon

All along, SLR camera It has natural advantages in focusing, picture quality and manipulation, which has established its king position in the field of photography. and Canon EOS   70D On top of these traditional advantages, it also has its own secret weapon, namely the innovative full pixel dual core CMOS AF technology. The emergence of this technology has greatly improved the efficiency of taking photos and videos with the SLR camera, and even ordinary consumers can skillfully operate it. Is this technology really as amazing as it is said? You will know after reading this article.

EOS 70D Yes Canon A mid-range SLR camera released in July last year can be called the most pioneering product among Canon SLR cameras within 10000 yuan in the past five years! The APS-C sensor with 20.2 million effective pixels, DIGIC 5+image processor, and full 19 point cross focus system are bound to bring a good shooting experience. The biggest feature of the camera is full pixel dual core CMOS AF technology. The addition of this technology has improved the focusing performance of the camera in real-time viewing.

The traditional SLR camera can achieve a very fast focusing speed in the optical viewfinder mode. This is because the SLR camera adopts "phase detection focusing". The phase detection focusing can instantly calculate the correct focus position, so that the focus can be quickly focused. However, when the camera is switched to the real-time viewfinder mode, due to the rise of the reflector, phase detection focusing cannot be used, so "contrast focusing" is replaced. In contrast focusing mode, the camera needs to judge the contrast difference of the picture by repeatedly moving the lens, and then lock the focus position, so the focusing speed is not as fast as before.

Before the advent of EOS 70D, SLR cameras had no good solution to this problem, and the focusing speed under real-time shooting was always unsatisfactory. However, after the emergence of EOS 70D, it solved this problem at one fell swoop with full pixel dual core CMOS AF technology.
