“D— —– —- AF”

I don't think that's the name of the new technology, I think it refers to what we've had in the past.   Before I got my 5D3 I was always saying:  Damn autofocus!

The surprise is that the 70D will focus better than the 1DX and that only Rebels and xxD will get top AF from now as the new Canon responds to constant cries from customers that the lower tier bodies always have worse AF.  ;D ;)

Somehow I don't think that it will have more capabilities and 'focus better' than the 5d3/1DX. From what I've seen Canon has a history of introducing some new bits of technology in various forms in the lower end models, and once they see if it's useful or the kinks get worked out, they put it as a flagship feature in the top end cameras, but doing it better.

Not having used the 7D, I've heard it's AF control interface is similar to the 1DX and 5d3. I'd guess Canon was testing out that way of AF control, and found that it worked well and just improved/tweaked it a bit and used it for the 5d3/1DX AF control.

"Damn autofocus..." was my 1st thought also. 

Someone else said it's 6 times faster than the EOS M.  Nothing personal about that input but hummm, isn't 6 times zero (or almost zero) still zero?

But on a serious note, I've been thinking they would make at least 1 major/substantial change in the 70D & maybe this would fit the bill.  If they can give a much faster/more sensitive autofocus to the 70D & EOS M, they'll still have plenty of room for an upgraded crop sensor like 7D2 (ie: 10-12 fps, mag body, full weather sealing, dual digic 6, the new af system, etc.).

It will only be for video, let the flame fest begin when it's released  :-\

I remembered I read this new AF somewhere and yes, here: http://www.canonrumors.com/2013/04/the-future-of-eos-m-cr1/.

A new autofocus system will come with the new cameras and promises to be “class leading”.

And this was for the next EOS-M, so I'm sure it'll be a new type of Hybrid AF.

We'll see.

Yeah, if they said 7DII, I'd have hope for it being some major . . . but 70D, it'll have to be video.

D-U-A-L AF... some sort of stereo solution for depth detection?

D-U-A-L AF, phase and contrast at the same time?

I haven't an informed guess, frankly.

On some unrelated level, I was reading about the camera-designs of the Kinect II and the original the other day, and was surprised that the dual cameras of the first-gen are to be replaced by a single camera in the new version.  By comparison, SONY's next EyeToy is rumored to move to a twin camera design. Outside of the videogame industry, TrackingPoint uses a proprietary stereoscopic approach for their new optics system.

I think this is a rambling way of saying that I'm seeing a wider application of dual-optic design in different consumer products, and cameras are overdue for similar methods.

I don't know how a stereo design can be applied to a single lens DSLR--IF that is the Big Reveal--but the general concept of "twin-something" is intriguing to me.

Phase detect already does that through a single lens - aligning the image projected through the left and the right half of the lens.

I'm guessing this is simply Canon making an incremental change to the live view/video sensor based contrast/phase hybrid AF system already found in the EOS M/Rebel lineup, aiming to finally get it working fast. Hopefully it is more than that though - some sort of new AF chip which includes contrast detect for stills, to allow for better subject tracking, including out to the edge of the frame?

This is what Canon does with the new sensors with phase af pixels, but maybe in the future they'll add the ability to do phase and contrast at the same time while currently the phase af is just a helper to tell the general direction for contrast af.

This might be interesting if they'd not use live view but a semi-transparent mirror, maybe they've got a semi-transparent non-fixed mirror unlike the old system on my eos RT that took a lot of light away, but it had a lighting fast shutter release.

But I don't trust this to be good news until I've seen it really working, for my money I'd just like a 5d3- or d600-style old school af system at a reasonable price thank you very much.

Can't get the sensor better so they just improved the AF.  Sounds good... I want the digital eye control however implemented on a 19 points AF. Now that's fun.

Dark AF?? Dunno so I'll just throw in my guess! Maybe improvements in the ability to attain AF in really dark conditions. Like the 6D but better?

No, it is 1/6 as slow as the M

So does this mean that we are not going to see a 70D till July or later ?

Eye-control. That would be sick.


It also wouldn't be 'new technology'. Witness the EOS 3.

EOS 5 et al.  I would be great to have eye-control back in action.  I  miss that from my EOS 5.
