  1. The phase-detect side of this 70D sensor should provide a very high resolution set of data about depth in the image, right?
    Would it be possible to construct a depth image using this? What resolution would it have? And how accurate would that depth info be? (I know it's pretty accurate around the focusing distance, but is it still so for stuff that's out of focus? And if not, do you get any kind of useful info if you try to compensate that by going deep DoF?)

  2. for depth sensing - see the panasonic paper on ISSCC 2013 session on image sensors. They placed 2 pixels under one microlens for purpose of depth sensing.
