The Canon EF mount Rokinon 35mm T1.5 Cine AS UMC Lens was
developed primarily for film and video applications. The cine version of
Rokinon's 35mm lens features industry-standard gearing for the focus
and aperture ring, and the aperture ring has been de-clicked for smooth
iris pulls. The aperture and focus scales have also been relocated to
the side of the lens, where it is easier for focus pullers to read them.
This lens is compatible with full-frame sensors and can also be used on
APS-C-sized sensors, where the 35mm-equivalent focal length will be
56mm. The optical construction incorporates two high refractive index
elements and one aspherical element to reduce chromatic aberrations and
distortion to produce sharper imagery. Additionally, a UMC coating has
been applied to lens elements to minimize lens flare and ghosting for
more contrast-rich images.
