Rokinon's carbon fiber cinema prime — 24mm T1.5 XEEN CF for Canon EF with improved build.
The Rokinon XEEN CF 24mm T1.5 is a cinema prime from the XEEN CF (Carbon Fiber) series, released approximately 2017. The CF designation indicates carbon-fibre barrel construction for reduced weight versus the original aluminium XEEN series, using the same optical formulas. Canon EF mount. Part of a matched set covering 24mm through 135mm focal lengths.
T1.5 maximum aperture. 24mm focal length. Canon EF mount. Carbon-fibre housing. 114mm front outer diameter — cinema-standard. 0.8-module-pitch gear rings. At approximately 1,150g. Close focus approximately 0.3m.
The XEEN CF retains the same matched optical design as the standard XEEN aluminium set — consistent 114mm front diameter, matched colour rendering, T-stop calibration — while reducing weight through carbon-fibre barrel use. The Canon EF mount version is compatible with Canon EF-mount cinema cameras, EF DSLRs, and Canon RF mirrorless via EF-RF adapter.
On the used market the Rokinon XEEN CF 24mm T1.5 Canon EF is an affordable carbon-fibre cinema prime. Condition checks: Canon EF mount contacts and electronic coupling, iris ring smoothness, carbon-fibre barrel for cracks (particularly around the mount interface), front element and coatings.
