Whether or not a camera/digital-back is compatible with a CF card depends both on the firmware version of your camera/digital-back. Firmware allows the camera to speak the “language” of the new card. If your firmware doesn’t support a particular CF card one of two things will happen

  1. you’ll get an error message stating that the card is not readable/valid
  2. you’ll be able to shoot to the card but receive error messages when the camera goes to save a capture or receive sporadic error messages – the resulting files may or may not be readable on the computer

Obviously #2 is worse than #1 because you’ll think that things are ok when they are not. To help avoid this we’ve listed below the CF cards that Phase One has specifically tested with various Phase One digital backs. These are NOT a comprehensive list of all cards that will work – many many other kinds of cards are fully compatible. This list however represents complete assurance by direct testing.
