MAKE SURE YOUR USB IS FORMATTED TO ARRI: MENU_MEDIA_PREPARE USB MEDIUM Make sure the USB is in the camera. Also create a "LDA"file and add the lens" .tab" file into it.
you pay 7000 dollars for a WIRELESS remote that talks to the camera, you can set everything on the camera with this amazing remote, but it cant send over the lens file? that is just crazy stupd!
