Sony 128 GB FMU
The Sony 128 GB FMU is a solid state memory unit for the Sony FS-100 camera. It allows you to dual record footage to both SDHC cards and the FMU at the same time*. The FMU fits into the side of the camera and outputs to your computer via a USB mini cable.
*NOTE: When shooting slow motion, you are not able to dual record. Footage will be recorded to the memory unit that you select in the "REC SET" menu.
