To clarify, yes, I was trying to say if DSLR contrast AF could be speeded up if they sample faster in a similar way to how Panasonic describe. I'm assuming the DSLR sampling rate will be at most that provided by the video modes, or up to 60fps typically.

It is not the sample rate that makes contrast detect AF with PD -AF systems slower, but rather the motor electronics/management of the lens which is designed for PD-AF.



Put a 4/3rds lens on a micro 4/3rds camera, and you will see the same thing... Panasonic can be that fast because the lenses are designed with the contrast detect AF system from panasonic in mind. Only with micro 4/3rds lenses.
