One biggie is the ability to use the on-sensor PDAF focusing system with Sony A-mount lenses, and another is the ability of the on-sensor PDAF focusing system to have full functionality AND speed with Canon lenses via a simple adapter. 42MP, back-illuminated, 4K internal video, 5fps, 399 PDAF points, and a bunch more...all wedged into a compact body.
