Check out Jeff Wignall's ProPhotoDaily interview with Tony Gale about using the Sony α6300 for its speed capabilities.
"[F]or some time DSLR cameras were faster to focus, but when the α6000 came out it was quite fast and now with the α6300 it is crazy fast and has the fastest autofocus of any camera I have ever used. Also being able to shoot low or high with the tilting LCD screen without the limitations of having to look through a viewfinder can be a huge asset. The α6300 is the first camera I have ever used that tracks runners going as fast as they can." -Tony Gale in ProPhotoDaily
