The real technological highlight and the biggest innovation of the Canon EOS 70D is the Dual Pixel CMOS auto-focus. That’s not to say the EOS 70D falls short as a stills DSLR, but the new AF is a real game changer. We have seen many test videos, but the performance is so amazing that I think a few more won’t bother you, especially if you are into videography and want to learn more about the 70D’s AF.
The video above (by YouTube user canonplex, thanks to the reader who sent the link) shows a different view on the 70D’s AF. The two videos below [via dicahub] were taken while driving at 100 km/h (approx 60 mph) and pointing the AF to the road sign. Note that the AF area is larger as the sign (while far away from the sign) and until the road sign comes close it was not sure if the AF was focusing on the right spot – indeed, it did, and it did whit great precision. The video were taken using a production model of the EOS 70D and a Tamron 90mm f/2.8 Macro 1:1 VC lens, M mode video and f/2.8 were set. The tracking of the Dual Pixel CMOS AF is amazing!
