    How can you have simultaneous phase detect and contrast detect autofocus without a translucent mirrror?

    Beside the traditional AF sensor, extra phase detect module is built right on the CMOS sensor itself.

    QFT.

    40mm, an interesting compromise. Long enough to be normal on FF, short enough to almost be normal on crop. I think I will probably end up with one... the price is certainly right. But f/2.8 is making me have to think about it. If it were even f/2.2, it would be a no-brainer.

    Canon doing pancake is great news for all, I do hope they introduce more.

    Does it use the CMOS sensor's pixels or are there additional phase detecting pixels in there somewhere?

    Interesting... so some pixels are sacrificed (at least half of the pixel) to act as phase detectors
