I have tested both the EM5 and GH3 but would not care to say one is better than the other at follow focus. They are using the same sensor (probably)  the same readout rate of 240 fps and both use CDAF without PDAF,  so there appears to be no pressing reason why one might expect one to be better than the other.

Just a note that the GH3 240fps AF readout only works with the Lumix X 12-35mm and 35-100mm lenses so far, and probably it only works in farily well lit situations, e.g., daylight.

That it would work at 240 Hz with these two lenses only is news to me. What's your source for that claim? I see no reason at all why theĀ AF frame-rate would be lens-dependent.

I'm not sure if the E-M5 can utilize 240fps with any lens, or just for some of the more recent ones. Given that the GH3 can only use this feature with the two newest premium zoom lenses, I have some doubts.

The original E-M5 announcement says it can do 240 Hz in AF-C and doesn't say anything about this rate being lens-dependent.
