The CN8 x 15 IAS S/E1 and CN8 x 15 IAS S/P1 can be mounted on cameras equipped with large-format (Super 35mm equivalent) sensors, providing a focal length range of 15-120mm through high optical zoom. What's more, the lenses realize improved performance compared with their predecessor models1 in a more compact and lightweight design that enhances mobility and enables easier shoulder-mounted operation.

By using the built-in 1.5x extender, the CN8 x 15 IAS S/E1 and CN8 x 15 IAS S/P1 can toggle to a focal length range of 22.5-180mm. Thanks to an expanded image circle, the lenses can be used with 35mm full-frame sensor cameras, such as Canon's EOS C500 Mark II (released in December 2019) and EOS R5 C2 (released in March 2022) digital cinema cameras. With such broad support for large-format sensor cameras, the lenses support video production for users who demand cinematic visuals with shallow depth-of-field.

In addition to supporting 12pin serial communication protocol standard used by broadcast camera systems, the lenses also support communication functions via the lens mount. The CN8 x 15 IAS S/E1 supports EF mount communication3, while the CN8 x 15 IAS S/P1 supports the /i Technology protocol designed by Cooke Optics, as well as eXtended Data technology from ZEISS. With the capability to externally output a wealth of lens information to the camera via the lens mount during filming, the new lenses contribute to greater efficiency not only during recording, but also in VFX4 and post-production workflows.
