Canon EOS 70D "dramatically improved video friendly focusing" - Sept 2013 release.

As compared with older DSLRs now a days there have been a tremendous change emerged in DSLRs. DSLRs can shoot amazing quality videos up to 1080p. But their autofocus feature is primarily designed for shooting stills and can result in stuttering/blurred movie footage, which is why most of the filmmakers do not use it.

However, Canon came up with an innovative thinking that this could change with the launch of magnificent EOS 70D. Canon embedded new AF (auto focus) system in the Wi-Fi-toting 20.2-megapixel DSLR, which is said to offer much faster focusing during Live View. 

In simple words they made Auto Focusing more dynamic in nature that we can use this as a camcorder.

EOS 70D is a new mid-range DSLR which follows on the aging 60D. While the CMOS sensor has received a modest upgrade of 20.2MP, and the camera has gained the wireless connectivity capability from 60D. Apart from these normal changes AF system is the biggest change in 70D. This newly improved Dual Pixel CMOS AF is said to vastly improve Live View focus speed and subject tracking. 70D features a 3-inch vari-angle touchscreen LCD with 1040K dots, like the same on 700D. Canon 70D is subject to release in coming September and for a body only price claimed by Canon, USA is $1200. I will be bundled with EF-S 18-55mm f/3.5-5.6 IS lens for $1350. Canon, India yet to reveal the price.
