Spot the difference! Those crafty Chinese are at it again!
Cinematics have started offering ‘film lenses’ which are Zeiss Compact Prime copies – cinema modified Zeiss ZE (Canon mount) full frame lenses at up to one quarter of the price of a real Compact Prime. Optically they remain the same as standard ZE but as you can see from the image above a CP.2 style housing is added (left) to create a “CT.2”.
This includes gearing for a follow focus, T-stop marks instead of F-stop, cinema standard front thread size as well as a stepless aperture ring.
