    Is that how small the expansion of AF area is?

      It appears that the design of mirrored AF is nudging at its limits. It may be physically impossible to expand it further without making the camera bigger.

        Canon loves to recycle old tech. Its more likely they just didn’t want to make a newer larger secondary mirror and af block. I don’t see why you can’t have points almost to the edges.

          I don’t know if you’re aware of this, but…

          See the first answer. You not only need a larger mirror, but also larger diameter lenses. With current mount specifications it’s almost impossible to put a wider AF block on FF cameras. Basically, the edge of APS-C is the limit.
          Now, Pentax could put a larger AF block on the 645 cameras, but it probably isn’t a sound investment for them (they still reign supreme in that market this far, with only the K-3’s SAFOX module, hah!).
