70D:
148X111X74 (vol. 1.216)

139.0 x 104.3 x 78.5mm

You're right, Carlos. I made a mistake and took the 7D dimensions. So, it's vol. 1.142 and slightly smaller.

The main reason I chose my lesser-spec'd 50D over the 60D was because of 'feel'. I wanted my camera to be an extension of me rather than an ill-fitting attachment. I have medium-sized hands so we're not talking big-fumbling fingers all over the camera. But that's how my hands feel on a 60D and Rebels.

The 70D is a damn fine camera. I think the tech in this camera holds some exciting possibilities for the future!

Confirmed from the Canon Europe 70D site: it may have the 7D's 19-pt sensor array & dedicated AF processor, but it doesn't have the same degree of flexibility & customizability. The 70D appears to only offer Single Point, Zone, and Auto 19-point; AF point Expansion and Spot AF are MIA. The dedicated AF area expansion button near the shutter button should have been made a programmable M.Fn button instead, just saying.

Yes, the above DPR preview doesn't contradict the info from CPN Europe. Notice there is no mention of AF point expansion & Spot AF in the list you quoted.

apologies I thought it made have just been different wording in the list for the items you mentioned  :-\

Does anyone know if their smartphone app can act as an intervalometer?

Not sure if this was answered but YES - Triggertrap is awesome https://www.youtube.com/watch?v=ae6wibhMmI8

I would like to know why Canon doesn't put 60fps in 1080p when some cheaper cameras and Sony Alpha have it. Technical difficulty or Marketing ?  ::)

Does live view phase detect AF require things like lens microadjustment like viewfinder phase detect?  Live view contrast AF being the gold standard for AF accuracy, not needing microadjustments.

Which makes me wonder...while not performing AF function, what are those extra 20M pixels doing ??? seems like an awful lot of sensor real state to waste isn't it? What if those pixels are actually put to contribute to IQ when the picture is grabbed? how about some interpolation / oversampling to tremendously improve high ISO performance....

Just wondering and dreaming...  ::)
Its a APS-C sensor, no real estate is wasted, all the sensors are used in a image.  The split halves are for autofocus, but they are combined into one sensor when shooting.  There is a lot of information describing how it works, including the patent underlying it was posted on CR a while back.

When you are doing focusing using the image sensor, there is no need for AFMA. When you use a separate focusing sensor (regular through-the-viewfinder mode) the image will focus accurately of the focus sensor. When the mirror flips up the light falls on the image sensor and the picture is taken. If everything was manufactured perfectly, it would also be in focus. Due to manufacturing tolerances, heat expansion, wear and tear, and sometimes things slightly shifted from a drop or just not quite calibrated properly from the factory, this image might be slightly off on the image sensor. AFMA gives you a "fudge factor" to adjust the lens focus to compensate for this.

Focusing with the image sensor eliminates all of this..... way simpler... and that is why mirrorless cameras don't need AFMA.

Gold, but not platinum - there was a recent article on lensrentals dr. neuro keeps posting here that says lv also isn't 100% accurate; also if you want best reliability you might want to try focus peaking (magic lantern) to focus where you want and not where the lv focus box says the contrast is.

Confirmed from the Canon Europe 70D site: it may have the 7D's 19-pt sensor array & dedicated AF processor, but it doesn't have the same degree of flexibility & customizability. The 70D appears to only offer Single Point, Zone, and Auto 19-point; AF point Expansion and Spot AF are MIA.

Knowing Canon, this doesn't come as a surprise, they want to sell the still produced 7d1 & the 7d2 later on :-\ ... though magic lantern might be able to backport some of these features as they also offer af patterns on the 9pt af systems that'd be only single/all otherwise.

Man, it's about time they came up with a good new (actually NEW) sensor.

Sure. Because dividing every pixel in half for PDAF sensors covering the majority of the CMOS image sensor area has been done to death...   ::)

That's what I'm saying. Dick. Canon was leading the pack for years at the consumer onset of digital, but after the T2i, they completely stagnated. What I was saying was that it's about time we see Canon come back out on top with something nobody's thought of before. Every sensor was "new" when all they did was add four pixels' worth of faulty phase-detect autofocus to the T2i sensor or change up the filters a little. Same garbage. It's been at least three or four years since they were best, and all I'm saying is that it's nice to see them putting in the effort again.
While appreciate your appreciation of sarcasm, I feel you should be able to read the posts better than that, let alone what's between the lines.

disclamer: not a native english speaker here...

Isn't this just a case of mixing past and present tense in a sentence wich is leading to misunderstandings?

shoudn't you have used "It was about time they came....."  in stead of "It is about time they came..."??

then again not a native english speaker here..  ;)

Still looking to the EOS 70D as my next purchase but following release of the Nikon D5300 announced this week with 24MP sensor, no optical low pass filter & built in WiFi & GPS at £729*,  the Canon EOS 70D at £1079* is looking  rather over-priced; I'd hope to see some heavy reductions after Christmas...
