Angenieux's EZ-1 30-90mm S35 Cinema Lens with PL Mount is a fast zoom for 3-perf Super 35mm sized sensors that has been designed from the ground up to utilize interchangeable rear optical assemblies. This allows you to use the same lens to cover Super 35 or Full-Frame/VistaVision-sized sensors by swapping out the rear optical assembly. In addition, the rear assemblies allow you to swap the lens mount from PL to Sony E or Canon EF.
