Building on the success of the well-regarded CP.2 lenses, ZEISS's CP.3 Compact Prime Lenses offer the same full-frame sensor coverage and classic ZEISS look in an updated form-factor and with improved mechanics and lens coatings. This lens also includes the new eXtended Data connections which transmit essential lens metadata through both a Cooke /i interface on the mount itself and a 4-pin LEMO connection on the lens body.
