The zeiss CP.2 21mm T/2.9 PL Cine Lens is part of the second generation of CP
cinema lenses that were the first to offer full-frame 35mm coverage of large
sensor DSLRs. What distinguishes the CP.2 from its PL-mount-only predecessor is
its interchangeable lens mount, which allows the included standard-cinema PL
mount to be easily swapped out for an optional canon EF or nikon F 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.
