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.fegari said: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... :

Mark D5 TEAM II said: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.

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.
If Canon could AT LEAST match the D7000's sensor rating I'd be happy. Until then, I won't buy anything from Canon and I even might get something from Sony or Nikon. The 70D's AF would be nice enough on a mirrorless body but doesn't justify getting one since I don't do movies.LesC said: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...

Marsu42 said:Again, as for the sensor 24 vs. 20mp: your lenses have to be able to resolve this and these differences are minor in comparison to a real step up like the 36mp of the d800, so that won't matter much.
Marsu42 said:Also the 70d's price is already surprisingly low for Canon's standards...
