All Canon DSLR's with video can do AF in video mode. You just have to press the AF button or half press the shutter depending on the model.

The newest Canon DSLR's like the T4i, T5i, and SL1, all have Continuous AF in video mode. Any AF lens will still do continuous AF with these cameras, but STM lenses are quieter and smoother.

The 70D will also have Continuous AF in video mode and it will work with both older lenses and STM lenses.

You are right!


6D | 24-70L f/2.8 I | 40mm f/2.8 | 50mm f/1.4 | 85mm f/1.8 | 430EX II

Are you sure about that? I mean, On my 7D I can focus prior to starting the recording of the video automatically, but during filming I have to focus manually. Or maybe I am unaware of a feature? (i do very little video - just the kids)

Yes, you can AF during video but the results are not very good. With the 7D you can just press the AF ON button on the back while in video mode.

Wow and I thought Canon doesn't have any more tricks up its sleeves...

DPR said it best and I can't wait to see Dual Pixel CMOS AF appear in a full frame camera and their mirrorless system. Of all of the major players in the mirrorless market, I think Canon have the weakest system. Assuming Dual Pixel CMOS AF works as intended, then Canon will have what it takes to take on the OM-D and the GH3.

I'm still a little skeptical with what DPR said about Dual Pixel CMOS AF's very low if not impossible to have front or back focusing issues. Isn't this possible with phase change technology? If front and back focusing problems is all but eliminated, then what advantage will contrast detection AF will have then? If not, then Canon should go all out and implement Dual Pixel CMOS AF throughout its lineup of cameras.

My one concern is that Dual Pixel CMOS AF is limited to f/11 and faster. For APS-C, it's not a concern for me. However, if they implement this in their FF lineup, I hope it can go as low as f/16!

2 processors from 2009 are not very likely to be superior to a single one from 2013. It's been a while.

exactly what ive been saying,
heck, my phone has a quad core processor and my desktop from 2010 only has a dual core.
technology is better now than 4 years ago. This digic 5+ COULD be better than dual digic 4.
Canon says digic 5+ is 17x faster than digic 4.

The way I read it, Dual Pixel CMOS AF is limited to f/11 where most cameras are currently limited to f/5.6 or f/8.

I guess that means it will still AF at f/11 with a 2x teleconverter on a f/5.6 lens.

Do you really want it to go to f/16 ?

Engadget has hands-on videos posted with a list of the lenses used at the end-credits of the videos

http://www.engadget.co​m …07/02/canon-70d-hands-on/ (external link)

I was dead-set on upgrading from my 50D to a 6D for it's low-light capability. The 70D is supposed to be good down to -.5 EV on all cross-type AF points. The 6D is at -3 EV on center and +.5 EV on the outer AF points. This makes me wonder if I should rethink the 6D and possibly go with the 70D and better glass. Gah!

7D has Dual Digic4 PLUS a dedicated processor for AF alone. People think that one of the 'Dual' Digic4 processors is for AF.

But still I do believe Digic5+ (which is a 2012 processor, not 2013) will do the trick. 7DII will most probably have Digic6, since it was introduced just a few months ago.

Yup, it's that 4 or 5 year-old dedicated processor that's responsible for the AF that still beats any Canon camera without such a processor.

It's the same as PCs. No matter how fast CPUs get you'll still want a dedicated graphics processor (or two) if you want top performance.

5D3 is single processor, no? It seems to do just fine ;)

Nope, 5D3 also has a dedicated AF coprocessor...

-edit- one concern this raises of course is compatibility with Sigma lenses and such... If you're planning on getting a 70D might be best to wait till after someone tries to ensure Sigma's stuff works correctly...

It will be interesting to see how the new 20mp crop sensor performs in this camera. If it's a big improvement on the 18mp sensor and it performs well at high ISO then this will be an absolutely fantastic little camera. Can't wait to see the 7D II though...

I really have high hopes that this sensor is on par with Nikon/Sony/Pentax Dynamic Range...
