Thanks for the video and clear-up.  PDAF looks to be useful now.  However what is your source of information that the 50mm 1.8 OSS is not supported?  I think that is a big omission to not have that PDAF supported as its the only native lens that shoots portraits with thin DOF?

Got answers from Sony representative:

E50 will eventually got the update, so just stay tuned. the lens update is totally separated from camera update, so they won't wait for camera firmware sync. When it's ready, Sony will release them.

From the experience I play with 18-55 with update to PDAF

I won't put too much hope that a lens firmware update can drastically improve the E50 AF performance.

Yes, the PDAF do make the lens merely hunts in AF-C, but in AF-S it's still hunts like CDAF, I don't know why, it's not work like real PDAF DSLR.  maybe a slightly better than CDAF. I don't know if it's the old generation lens problem or the PDAF not work as it should be. To me the biggest problem is the lens motor Sony used in those lens seems not capable to provide lighting fast lens AF movement. And I believe E50 suffers this the most.
