As previously reported, Canon’s new autofocus system, dubbed the Dual Pixel CMOS AF (DPA) is an innovation in autofocus technology. According to CNET, a single photodiode, or the element on a sensor that collects light and converts it to an electrical signal, only passes on image data.
In the EOS 70D, the DPA splits each photodiode into two, comparing the signals from each half by using an algorithm for autofocus that phase-detects. The new feature makes the camera faster by driving the lens into autofocus.

The 70D also has manual-focus updates. Like the high-end 7D, the camera includes a touch-screen interface for Live View and video recording. It also gains Wi-Fi for wireless control and file transfer.
There are no radical changes to the outside design, but the camera’s operation is heightened due to these simple changes that Canon is implementing. Other updates include the Live View/Movie switch and record button, and a lock switch for the multi-controller.
The Canon EOS 60D remains the second best-selling dSLR on Amazon. The price also dropped form $1,099 to as low as $599, skyrocketing sales.
“The Canon 70D is a more all-round multi-media device. For many people the improved video focusing and built-in wireless capabilities for sharing images will instantly make a compelling argument in favor of the 70D,” writes Gizmag columnist, Simon Crisp.
Recent reviews by Imaging Resource states that this device brings in “a new technology so unexpected that there’s no way we could be disappointed – even if it may not have delivered the significant upgrade in still image quality that everyone wanted or expected.”
The full-time continuous autofocus system lives up to its promise as well, where it quickly and accurately uses the Dual Pixel CMOS AF operation. It also improves a bit in resolution with 20.2 megapixel APS-C CMOS sensor from an 18 megapixel one.
The camera just became available for $1,199 and a video of the product review from Andromeda can be viewed below:
