Just buy FULL FRAME lenses and forget about S35 ones. Once Canon will have decent Cinema Set for $5k each i can't see Sony selling well. Just look at Zeiss CP.2 range 15mm - 135mm in Full Frame. And look at their new Full Frame CP Zooms 28-70 and 70-200. Full frame is the way to go. New Dragon Sensor and Canon 1dc are the Tip of an Icberg and expect more Full Frame Cameras next 5 years.
