The EOS-70D camera was announced by Canon in August, 2013 with great fanfare and to rave reviews. One of the most exciting new technology is the Dual Pixel CMOS AF. You can see more exciting short films taken with the new DSLR body on Canon's website. Take a look at this side by side comparison between the Nikon D7100 and the Canon EOS-70D cameras.
Canon has an unusual method of introducing their newest technology. They put them on their consumer line of cameras first, before releasing the features on their professional models. Cases in point are their latest DIGIC processors and the Dual Pixel CMOS AF, all debuted on PowerShot and EOS-XX models first. Now, this advanced technology is also available on the Cinema EOS C300 and EOS C100 cameras with a paid upgrade.
More advanced version of the Dual Pixel CMOS technology will make their way into higher end models, like the EOS-7D Mk II, EOS-5D Mk IV and EOS-1D X Mk II in the not too distant future. I believe Canon has come across a winning technology and photographers and videographers are benefiting from it.
