My initial reaction was the same, soLong. Why waste so many pixels?


Well, I just read on the Canon site that each pixel consists of two diodes, which are read out seperately for AF, but combined for the image. So, there you have it, all "40 mps" fully available


Smart approach, IMO. Will be interesting to see how it performs in real life. That's certainly a nice attempt to increase tracking performance in Live View mode. An at the same time cover a lot more of the image with AF sensors.


If this works reliably, the logical next step would be SLT...

What is logical about SLT? It loses you the optical viewfinder, brings heat problems to the camera, and loses 1/2 stop of light. The last point may not be a big issue, but the other two are rather nasty. 

ALso, SLT was needed to bring PD-AF to live view/video (according to Sony).

Now live view has its own PD-AF, so exactly why is SLT a next logical step?
