Sony to launch A33 & A55 PELLIX cameras this year
Well looks like a potential good news for people who want DSLRs to take videos.
The PELLIX cameras have a fixed mirror which is semi transparent just like old film based canon EOSRT launched in the late 1989.unlike normal SLR and DSLR where the mirror moves in order for the light to hit the film or sensor.The PELLIX sensor is fixed .read more in wiki Pellicle mirror - Wikipedia, the free encyclopedia
KenRockwell in the canon 5D review said"If Hollywood uses the 5D Mark II to shoot major motion pictures, then why isn't it good enough for me, especially if I'm already carrying it?
Simple: DSLRs have no real autofocus! They all claim some sort, but it doesn't really work, at least not if the subject is moving, which is the whole point of movies.
Worse, manual DSLR focus won't work in real-time because the finder goes black while shooting video. You can't see much looking at a 3" LCD as things move around.
Now the advantage in using a PELLIX mirror is that you can now use Phase detection autofocus vs other dslr like nikon,canon which use Contrast autofocus.

some of the possible advantages of using this design
The mirror is fixed so there will be no moving parts. That should help you to get sharper images (like on rangefinders)
3) The camera will be more silent!
4) The camera can take pictures (stills!) at over 10fps
5) can possibly use optical viewfinder ,(current DSLR that shoot videos have one drawback which is they can't use the Optical Viewfinder)
