All our Zeiss CP.3 lenses are characterized by an excellent optical performance and a design adapted to the professional film workflow. All except the 100 and 135 mm lenses have the same outer dimensions and position of the gear rims (0.8) as well as a forn lens diameter of 95mm. The Zeiss CP.3 28mm/T2.1 EF is a wide angle lens of the Cp.3 series. Beside this version on PL we also offer the complete CP.3 ready adapted on PL-mount. If you want to use the lenses on Sony E-mount systems we recommend our Vocas PL to E adapter. If you want to use the Cp.3 lenses on Canon R systems like our Canon C70 or the Canon R5, we offer an adapter from PL to Canon R-mount.
