The Zeiss Compact Prime CP.2 35mm/T2.1 Cine Lens (EF Mount) is part of the second generation of CP cinema lenses that were the first to offer full-frame 35mm coverage of large sensor DSLRs. The Compact Prime mount lens is the latest members of the ZEISS family of lenses for digital and film cameras. The Zeiss CP.2 lenses share a common heritage with the Zeiss ZF.2 lenses. Designed to function on a motion picture set featuring larger more robust housings with consistent focus and iris gear positions. The Zeiss CP.2 lenses are the perfect bridge between HDSLR lenses and full-blown cinema lenses.
