Canon’s new EOS 70D model features a new CMOS sensor that uses twin photodiodes at each pixel location that allows AF during video capture, but how does that affect stills output? Read on to find out how well the new sensor performs in our labs.
Besides being this year’s update to the firm’s range of mid range APS-C EOS DSLR model, Canon’s EOS 70D brings unexpected yet welcome technological advances in the form of a proprietary 20.2 M-Pix Dual Pixel CMOS AF sensor. Each pixel has twin photo diodes that can be read together for image capture or separately for fast focusing during movie capture. Sensor sensitivity doesn’t appear to be adversely affected with the EOS 70D offering ISO settings up to 12,800, expandable to 25,600. In stills mode and continuous shooting up to 7fps.
The EOS 70D adopts a viewfinder based AF system with 19- cross-type subject detection points. Other notable features include a 7.7cm (3-inch) articulated touch screen with a very high (1.04-Million dot) resolution and remote shooting and image transfer with built-in WiFi.
Apart from the new autofocus system employed during movie capture, the EOS 70D can record full HD movies in 30, 25 and 24fps and 720p in 60 and 50fps using inter or intra frame H.264 (MOV) format. The camera is available now at $1,199 body only, or for $1,349, complete with the 18-55mm STM f/3.5-5.6 video oriented starter lens.
