In this manual you learn how to change the mount of a ZEISS Cinema Zoom CZ.2 (abbreviation: ZEISS CZ.2) and how to match it to a digital camera. In order to explain the procedure, this manual uses a ZEISS CZ.2 28 – 80 which is scaled in feet with PL mount. Proceed in the same sequences to switch from or to any other mount that is available for the ZEISS CZ.2 (Canon1 EF, Nikon2 F, Sony3 E and MFT).
