The ACDB-989 is an interchangeable insert that fits on to Actus-G version. It can replace the bayonet holders AC-792, AC-793 and AC-78E and offers the possibility to use a digital back on the Actus-G series. You only have to add a fitting bellows and a SLW-adapter for your digital back.

This way you can easily switch from shooting with your DSLR or Mirrorless camera body to shooting with your digital back.
