Canon released a firmware update for the 5DM3 that included the ability to output uncompressed video on the HDMI port. Does anyone know if the 5DS outputs uncompressed video? I've wanted an external monitor for occasional use with DSLRs and ran across the Black Magic Design Video Assistant. It is 5" touchscreen monitor and includes video recording in multiple formats to high-speed SDXC cards. Not bad for a $500 product. I'm primarily shooting with a 5DM3 and 5DS right now and was wondering about the 5DS' output. Canon says nothing about it on their US site or in the manual that I can find.
