Autofocus systems are complex technology and it's an area that has seen continuous development for decades. Phase Detection AF has traditionally been the preferred system, since this provides the greater speed and accuracy demanded by the top pro photographers. It was the inclusion of PDAF that maintained the dominance of DSLRs as the pro choice throughout the 2000's, while mirrorless compact and bridge cameras were forced to use the slower Contrast Detection system.

Things are changing rapidly however and today's crop of interchangeable lens mirrorless cameras are sporting AF systems which not only rival, but actually out-perform their DSLR equivalents.
