Canon EOS 70D is a fully upgraded product. Canon has upgraded the three core components of CMOS, focusing system and processor from beginning to end. First of all, in terms of sensors, Canon EOS 70D uses an APS-C sensor with 40.3 million effective pixels, and the effective imaging point is 20.2 million pixels. This is the first time that Canon APS-C frame camera has broken through the 20 million pixel threshold. Higher pixels can bring better detail performance and post-processing space. In addition, the new sensor can achieve high-speed continuous shooting of up to 7 shots/s through high-speed reading of 8 channels.
