The Canon EOS 70D DSLR Camera features a 20.2 megapixel APS-C CMOS sensor and DIGIC 5+ image processor to ensure high-resolution images and excellent low-light sensitivity. Both the sensor and processor work together to produce well-detailed, clear imagery that exhibits natural tonality and color gradations with minimal noise when working in difficult lighting conditions. The processor also provides notable speed throughout the camera system, including the ability to record up to 7 fps in full-resolution, quickened AF speeds, and full HD 1080p video recording in multiple frame rates with manual exposure and audio level control.

Serving to benefit working with live view in both still and movie shooting modes, Dual Pixel CMOS AF is a powerful technology that revolves around the incorporation of two photodiodes within each pixel to provide an expansive phase-detection focusing system. This system affords focusing advantages that are similar to how a camcorder works and as such can focus on subjects in an incredibly fast and precise manner. The benefits of this system are three-fold: the ability to focus quickly and smoothly; the ability to truly utilize the vari-angle touchscreen LCD monitor to its full potential; and the ability to utilize a wide range of over 100 EF and EF-S lenses. Also benefiting from Dual Pixel CMOS AF is the Movie Servo AF mode, which enables continuous auto focusing when recording movies. This focusing mode is especially useful for maintaining critical focus on moving subjects and for realizing the near-silent performance of compatible STM lenses.

The 3.0" 1,040k-dot vari-angle Clear View II touchscreen LCD monitor profits greatly from the advent of the Dual Pixel CMOS AF system and its ability to utilize Touch AF focusing for finely controlled selection of the point of focus.
