Here's the video with the test. It's about halfway through. They compare standard zooms (Pana around 6x faster), Macros (Pana with 45mm around twice as fast) and one other test, the results of which I've forgotten, but the Pana won it as well.
 
The 70D should focus faster than another DSLR in live view mode. Somehow Canon have managed to give the impression that the 70D is generally faster.
 
They use different kinds of focus systems (PDAF Vs. CDAF). The two have different positive and negatives (namely in low light PDAF is more reliable and it likely works better for shots involving motion particularly high speed motion).

In the video someone linked they're comparing cameras based on single shot scenes in good light without any movement whatsoever. That's fine, if that's all the information you need, but there is more to a focus system than just a single scenario.

I think this whole thread seems really immature, like we have a whole bunch of people who either know nothing about focus systems or want to pretend they know nothing just so one camera "wins" over another. The fact is that both PDAF and CDAF have advantages in different scenarios and even m43 cameras will gain PDAF in the future (E-M1).
 
I you watch the video further, you realize that the Canon 70D behaves much better in video autofocus, with much less "pump" effect.

Different lenses is different light, more light is less "pump"

no, look better it is a macro lens Leica 3.5
 
very unexpected to be honest and this doesn't bode well for future technologies.

I has hoping it would actually be a breakthrough technology. This is a let down. Even if I am a m43 user with zero intention of going Canon.

LOL. Watched the video. IMO they have made the comparison to simply mock the Canon's "gamechanger" marketing label. That was the beef of the video.

Though the GH3 lost in one test: refocusing while in video. GH3 hunted, while 70D was not. I'm not sure what lens was used with GH3. They said it was macro video test, I presume they used the 2.8/45mm as in the other tests.

P.S. Anybody who want to watch only the mirrorless tests: skip to around after 18:00 for the stills test (3 min), around 24:25 for the video test (5 min). The GH3 fail in video test is closer to the end of the video test.

That wasn't the impression I got when I tried the 70D with the 18-55 STM against my GH3 with the 12-35.

What makes the 70D nicer is that, being PDAF, it doesn't have to rack the focus back and forth to lock AF. This makes AF transitions nicer 100% of the time. With the GH3 it sometimes still hunts a little in less well-lit situations.
 
I wonder how well would E-M1 with PDAF do for Video AF? Would it be like 70D or still like same old Oly?

Nope. See this thread: http://www.dpreview.com/forums/post/51955665

The G6 has faster C-AF than all but pro-level DSLRs tested.

G6 faster again.

I doubt the G6 is any faster than the GH3 (specs are basically the same). The idea that m43 can't do fast C-AF was true once upon a time, but not any more.

As for dim light, my GH3 locks on every bit as fast as my Canon DSLR gear, and is always accurate, which I can't say about PDAF.

Inmature? Explaining technic is that mature? Take a shot with a Gh3 and any other Canon camera and you will conclude that the GH3 shot is the one you will keep and there is no need to look at home and check all the burst shot from Canon!

Results counts not words!

That is what it is now, and what it is in the future we shall see!!???

Often the first shot in a timed action shot is the best. But sometimes (or often, depending on what you shoot) it is good to have several frames to choose from in a sequence.

using an STM lens in this clip. It definitely seems to transition smoothly and quickly.
