This update is for the MARK IV ONLY.

Firmware update for the Metabones EF adapter. Haven't done the update yet since it's Windows only. Grrr! I'll try it later at work. No really solid info on what exactly get fixed but hopefully the communication issue is resolved. Faster auto focus would be nice but doubtful.

Did the update. Pretty simple. Hard part was finding a Micro USB cable. I dont see any different in the overall performance so it's probably a bug fix.
 
I'm using a 70-200 2.8 IS mark I lens, and it still needs to have the camera powered up and down sometimes to get it to work, even after the update :~(
