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

5DIII also has a dedicated processor just for the AF, along with its Digic5+ processor.

hollis_f covered all that in another 70D thread.

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.

But will it do continuous auto focus @ F1.4 or is it the same as the sony thing that does it @F2.8 or higher.

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 ?

Am I misunderstanding something here? For landscape photography, there are plenty of people who want to use f/16 with FF. I said it's not a big deal for f/11 with APS-C. Please enlighten me if I'm off.

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 suspect the 70D will perform as well if not better than the 7D at the equivalent ISO. New algorithms can help address noise problems as resolution increases.

I reckon the 70D will trump the 7D on ISO performance, however, in terms of pure speed, Canon will not allow a xxD body to be better than a xD body. that would be foolish business. Like all things, they have the technology to make one single amazing camera, but trickle out the features and span them across different bodies, so you justify buying everything.

With that said, I'm still happy to have a 7D after this announcement. Canon cannot afford for a 7D mkii to fail, hence why everyones waiting on it.

Cameras focus with the lens fully open. They close down to selected f number when the shutter is pressed. Most cameras can onky focus with lenses that have an aperture of f5.6 or larger

I wonder what makes those lenses incompatible? At first I thought it might be lack of focus distance reporting. I looked it up and most of those old lenses do have it so it must be some other factor.

I don't think it's that. I have a 28-80L and I'm sure that reports distance....could be wrong.

I would typically agree, but the 7D is ancient in terms of Canon consumer-level bodies, at 4 years. It is quite conceivable that Canon would make the 70D better in every way, but time will tell. The 7D2, should it ever see the light of day, would then leapfrog the xD ahead again. Won't matter anyways, because Canon will stop making the 7D, and the only comparable APS-C choice at that time would be the 70D, regardless of where it would be deficient as compared to the 7D.

surprising the list includes some L lenses and the 100 macro. Not that the 100 macro needs AF for macro distances, but still - for me - surprising. I do use it for non-macro uses as well.
the 24-70 L version 1 is also on it. That might make some people a bit peeved. none of the 70-200 versions are on the list.
oooh boy. with jump of technology comes the side casualties as well....
because i would guess that if the sensor and the new AF is a success we shall see it in successive cameras (until the next upgrade)

by the way - according to the picture on the second link you have here - does it seem that there is only one custom mode on the dial..or 0?

I believe they're probably referring to the original non USM 100mm macro...I hope so anyway!

you might be seeing and confusing the 28-70 with the 24-70, at least i didn't see the 24-70.

also of note is that the list is lenses of "limited" capability, whatever that means.
