It is very exciting. I have to wonder what other surprises Canon has for us with DPAF. What are the implications of this? Does this mean that one can effectively calculate the distance of every pixel from the sensor and apply sharpening based on depth? I assume this would be very natural, or at least lens-like.
Some questions that occur to me:
Will this require a different type of demosaicing and raw processing?
Will libre tools be able to adjust focus, or will that be a DPP exclusive?
Why wasn’t this announced for the 1 DX II and 80D? Both use DPAF and are quite recent. And will they get this with a firmware upgrade or will Canon prevent that just to create demand for the 5D 4.
Questions, questions, questions. But purely out of curiosity, cannot afford these cameras.
