As you know Sony will get rid of the SLT tech on all future A-mount cameras. And that will be possible thanks to a new generation of Sony sensors with much improved Phase Detection system. But it looks like the whole world is now moving towards on Sensor Phase Detection autofocus. Today Canon announced their new 70D camera (specs and price at Amazon) having a Dual Pixel AF sensor. On paper this sounds like an incredible piece of tech. Basically every pixel on sensor can fulfill two tasks: Capture the light information for the actual image and be used at the same time to elaborate the phase detection signal. The main advantage of the tech is that you don’t have pixels that get waste for doing one job only. I am curious to see if Sony will have a similar solution or go a completely different route. One thing is sure, on sensor PDAF is what we will see on most future DSLR or Mirrorless cameras.
