Sony SLT A77II XAVC-S 2.0 Update
 

I just bought one of these as a backup/really-foul-weater camera to my A7S since I had heard XAVC-S was coming in a flash update (because it already has the new BionzX processor.) Lo and behold, Sony has delivered. Makes this camera a good choice for low-cost, weather-resistant run-and-gun now.

This new firmware update (2.0) brings faster focusing and adds XAVC-S 50/mbps HD video to the A77II DSLT camera. (NOT THE A7II, which already has XAVC-S and ships later this week.)

China Download (universal binary, works perfectly on US Cameras... I updated mine no problem.)
