Digital back can only shoot tethered with a powered hub.  The battery compartment will not hold a charge so this back is being sold “as is” with a known battery issue.

Tethering via Firewire is no longer supported on the latest version of Capture One 21 (version 14.2).  This is due to a new SDK driving the tethering, which applies to Windows operating systems as well.

Below are the highest OS and software version that will allow that:

  • Mac OS 10.15 Catalina
  • Windows 10 Build 1809 or earlier
  • Capture One 21 version 14.1 or earlier
