What type of cards do your camera's use? Are there any limitations?
Our camera's and digital backs use compact flash cards. Industry standards such as Sandisk and Lexar work fine.
There is now firmware available that allows some of our older models to accommodate UDMA 7 cards. The firmware is for the H3DII 50, H3DII 50ms, H4D 40, H4D 50, H4D 60, H4D 50ms, H4D 200ms, and CFV 50 and can be downloaded Here

All other H4D,H3DII and earlier models are not compatible with UDMA 7 cards. You should use cards that are labeled "UDMA" or "UDMA 6".
