BBC’s Johnnie Behiri (source: lensvid) had a chance to play around with a pre-production model of the Canon EOS 70D. While he was pretty impressed with the innovative Dual Pixel CMOS Auto-Focus of the 70D, he was less impressed with its image quality. According to Behiri the image seems to be on the soft side, noisy with moire and aliasing artifacts. However, he also stresses that used a pre-production model of the 70d, things can (and hopefully) will change when the 70D goes into production and will (presumably) have another firmware on board. The video below is the image quality test.
Next, we have two videos (source: imaging-resource) that definitely show how well Canon’s new Dual Pixel CMOS AF performs in real life (spoiler: very impressing). The videos come from the Japanese site Nikkei Trendy, and show the performance of the EOS 70D’s AF combined with face recognition: the child in the video is tracked while he is running.
More AF test, this time for stills, come from Japanese site Kakaku Magazine.
