The Zeiss Compact Prime CP.2 50mm/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 (such as the Canon 5D Mark II). What distinguishes the CP.2 from its PL-mount-only predecessor is its interchangeable lens mount, which allows the included Canon EF mount to be easily swapped out for an optional Nikon F or cinema-standard PL mount. For the first time, a single, affordable, professional quality lens can be used on both cinema and still cameras, opening up creative possibilities that keep your rig lightweight, versatile, and on budget.
